Consider the sequence 4,323,313,3

Answers

The explicit rule for the sequence 4, 3 2/3, 3 1/3, 3.... is f(n) = 4 - 1/3(n - 1)

Finding the explicit rule for the sequence

From the question, we have the following parameters that can be used in our computation:

4, 3 2/3, 3 1/3, 3....

In the above sequence, we can see that 1/2 is subtracted from the previous term to get the new term

Take for instance

2nd = 4 - 1/3 = 3 2/3

3rd = 3 2/3 - 1/3 = 3 1/3

4th = 3 1/3 - 1/3 = 3

And so on

This means that

First term, a = 4Common difference, d = -1/3

So, the explicit rule is

f(n) = a + (n - 1)d

This gives

f(n) = 4 - 1/3(n - 1)

Hence, the explicit formula is f(n) = 4 - 1/3(n - 1)

6-Tel, Inc. is a telecommunication services provider looking to expand to a new territory Z; it is analyzing whether it should install its own telecom towers or lease them out from a prominent tower-sharing company T-share, Inc.

Leasing out 100 towers would involve payment of $5,000,000 per year for 5 years. Erecting 100 news towers would cost $18,000,000 including the cost of equipment and installation, etc. The company has to obtain a long-term secured loan of $18 million at 5% per annum. Owning a tower has some associated maintenance costs such as security, power and fueling, which amounts to $10,000 per annum per tower.

The company's tax rat is 40% while its long-term weighted average cost of debt is 6%. The tax laws allow straight-line depreciation for 5 years. Determine whether the company should erect its own towers or lease them out.

Answers

Answer:

The present value of leasing the towers is $19,576,000 while the present value of erecting new towers is $20,273,000. Therefore, the company should lease the towers.

A motorboat travels 234 miles in 6 hours going upstream. It travels 342 miles going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current

Answers

The boat is moving at 48 mph while the current is moving at 9 mph in still water.

To solve this problem

Let's use the letters "B" for the boat's speed in still water and "C" for the current's speed.

The boat's effective speed upstream is B - C because it is moving against the current.

Since the boat is moving downstream against the tide, its effective speed is equal to B plus C.

Based on the supplied data, we can construct the following two equations:

234 = 6(B - C)

342 = 6(B + C)

Making these equations simpler:

39 = B - C

57 = B + C

Now that we have added the two equations, we may solve for B and C:

39 + 57 = 2B

96 = 2B

B = 48

Therefore, the boat's speed in calm water is 48 mph.

To find C, we can rewrite one of the initial equations with this value as a substitute:

39 = 48 - C C = 9

Thus, the current is moving at a 9 mph velocity.

Therefore, the boat is moving at 48 mph while the current is moving at 9 mph in still water.

How do you find Exponential Decay Rate?

1+b
1-b

Answers

Answer:

Exponential decay is represented by the equation:

y = a * e^(-bx)

where:

y is the final value

a is the initial value

b is the decay rate

x is the time variable

The exponential decay rate, b, can be found by taking the natural logarithm (ln) of both sides of the equation, then rearranging to isolate the decay rate:

ln(y/a) = -bx

b = -ln(y/a)/x

So, to find the exponential decay rate, you would need to know the initial value (a), the final value (y), and the time elapsed (x). Then, you can use the formula above to calculate the decay rate, b.

The expressions "1+b" and "1-b" are not sufficient to find the exponential decay rate, as they do not contain enough information about the specific scenario or data set.

You owe $2,264 on a credit card at a 14.7% APR. You pay $500.00 month. How many months does it take to pay off your balance?

Answers

Answer: 5.5 months

Explanation:

To calculate the number of months it will take to pay off your credit card balance, we can use the formula for the time it takes to pay off a balance with fixed monthly payments:

n = -log(1 - (r * b) / p) / log(1 + r)

where:n is the number of months it will take to pay off the balancer is the monthly interest rate (which is the annual percentage rate divided by 12)b is the balance owedp is the fixed monthly paymentFirst, let's calculate the monthly interest rate r:

r = 0.147 / 12 = 0.01225

Next, we can substitute the values into the formula:

n = -log(1 - (0.01225 * 2264) / 500) / log(1 + 0.01225)

Using a calculator, we can simplify this to:

n = 5.5 months

Histogram with title Food Festival Participants, horizontal axis labeled Age Group (year) with bins 0 to 19, 20 to 39, 40 to 59, and 60 to 79, and vertical axis labeled Number of People with values from 0 to 60 at intervals of 10. The first bin goes to 20, the second goes to 40, the third goes to 60, and the last goes to 50.

What percentage of the participants are ages 40 to 59? Round to the nearest whole percent.

Answers

Looking at the histogram, we can see that the age group 40 to 59 has a frequency of 30 people. The total number of participants can be found by adding up all the frequencies, which is 20 + 40 + 60 + 50 = 170 people.

To find the percentage of participants that are ages 40 to 59, we can use the following formula:

percentage = (frequency / total number of participants) x 100%

Substituting the values we found, we get:

percentage = (30 / 170) x 100% ≈ 17.6%

Rounding to the nearest whole percent, we get that approximately 18% of the participants are ages 40 to 59.

The segment lengths on the right triangle are given as follows:

JL = 13.[tex]KL = 13\sqrt{3}[/tex]

What are the trigonometric ratios?

The three trigonometric ratios are the sine, the cosine and the tangent, and they are defined as follows:

Sine of angle = length of opposite side to the angle divided by the length of the hypotenuse.Cosine of angle = length of adjacent side to the angle divided by the length of the hypotenuse.Tangent of angle = length of opposite side to the angle divided by the length of the adjacent side to the angle.

The sum of the internal angle measures of a triangle is of 180º, hence the missing angle is given as follows:

m < L = 180 - (30 + 60)

m < L = 90º.

Hence the segment JL represents the hypotenuse of the figure.

JL is opposite to the angle K, hence it's length is obtained as follows:

sin(30º) = JL/26

1/2 = JL/26

2JL = 26

JL = 13.

Segment KL is adjacent to the angle of 30º, hence it's length is obtained as follows:

cos(30º) = KL/26

[tex]\frac{\sqrt{3}}{2} = \frac{KL}{26}[/tex]

[tex]2KL = 26\sqrt{3}[/tex]

The return on equity (ROE) for a project financed with 100% equity or 50% equity and 50% debt, given different levels of earnings before interest and taxes (EBIT) are 20.3%, -5.4%, 36.2% and  -20.3% respectively. So, the correct answers are A), B), A) and A). if Galaxy Corp. proceeds with a recapitalization then  Basic earning power (BEP), Return on assets (ROA), Net income are likely to increase. The correct option is A), B) and E).

ROE = EBIT*(1 - T)/Total Equity

Where T is the tax rate and Total Equity is the amount of equity used to finance the project.

If the EBIT is $145,000, then

ROE = $145,000*(1 - 0.30)/$500,000 = 20.3%

Therefore, the answer is 20.3%. So, the correct answer is A).

If the EBIT is -$45,000, then

ROE = -$45,000*(1 - 0.30)/$500,000 = -5.4%

Therefore, the answer is -5.4%. So, the correct answer is B).

If the project is financed with 50% equity and 50% debt at an interest rate of 11%, then the cost of equity can be calculated as follows

Cost of Equity = EBIT*(1 - T)/Total Equity

Cost of Debt = Interest Rate*(1 - T)

Weighted Average Cost of Capital (WACC) = Cost of Equity*(Equity/Total Capital) + Cost of Debt*(Debt/Total Capital)

ROE = EBIT*(1 - T)/Total Equity

ROE = [$145,000*(1 - 0.30)/($500,0000.50)] + [$145,000(1 - 0.30)0.50/($500,0000.50)*(1 - 0.11)]

ROE = 36.2%

Therefore, the answer is 36.2%. So, the correct answer is A).

If the project is financed with 50% equity and 50% debt at an interest rate of 11%, and the EBIT is -$45,000, then

ROE = -$45,000*(1 - 0.30)/($500,0000.50) + [-$45,000(1 - 0.30)0.50/($500,0000.50)*(1 - 0.11)]

ROE = -20.3%

Therefore, the answer is -20.3%. So, the correct answer is A).

If Galaxy Corp. proceeds with the recapitalization, the cost of debt is likely to increase since the firm is issuing new long-term debt. Therefore, the cost of debt (rdrd) will increase.

However, the basic earning power (BEP) and return on assets (ROA) are likely to increase since the firm will have a higher proportion of debt in its capital structure, which will increase the financial leverage of the firm.

As a result, the net income of the firm may also increase. The cost of equity (rsrs) may or may not change depending on how the market perceives the increased financial risk associated with the higher debt level.

Therefore, the items that are likely to increase are Basic earning power (BEP), Return on assets (ROA), Net income. The correct answer is A), B) and E).

Solve the simultaneous equation graphically : x + y = 3 and 3x - y = 1.
( Taking the range of values of x from - 1 to +3​

Answers

Answer:

x + y = 3 and 3x - y = 1.

Step-by-step explanation:

For the equation x + y = 3, we can find the x-intercept by setting y = 0 and solving for x:

x + 0 = 3

x = 3

So the x-intercept is (3, 0). Similarly, we can find the y-intercept by setting x = 0 and solving for y:

0 + y = 3

y = 3

So the y-intercept is (0, 3). We can plot these two points and draw a straight line through them to represent the equation x + y = 3. The resulting line has a slope of -1 and a y-intercept of 3.

For the equation 3x - y = 1, we can find the x-intercept by setting y = 0 and solving for x:

3x - 0 = 1

x = 1/3

So the x-intercept is (1/3, 0). Similarly, we can find the y-intercept by setting x = 0 and solving for y:

3(0) - y = 1

y = -1

So the y-intercept is (0, -1). We can plot these two points and draw a straight line through them to represent the equation 3x - y = 1. The resulting line has a slope of 3 and a y-intercept of -1.

Now, we can visually determine the point where the two lines intersect, which represents the solution to the simultaneous equation. We can do this by looking at the graph and finding the point where the two lines intersect. Using the given range of values of x from -1 to +3, we can plot the two lines and find their intersection point:

[i dont know wheres the graph image but just show it so you can explain that]

The intersection point is approximately (1.1, 1.9), which is the solution to the simultaneous equation x + y = 3 and 3x - y = 1.

The critical value for a two-tailed test at the 0.05 significance level is 1.96.

The null hypothesis is that there is no difference in the proportion of men and women intending to vote for Donald Trump, and the alternative hypothesis is that there is a difference.

The test statistic is given by:

z = (p1 - p2) /√[(p×(1-p)×(1/n1 + 1/n2),

where p = (x1 + x2) / (n1 + n2) and x1 and x2 are the number of successes in samples 1 and 2 respectively, and n1 and n2 are the sample sizes of samples 1 and 2 respectively.

In this case, x1 = 120, x2 = 132, n1 = 250, and n2 = 240.

Plugging these values into the equation gives us z = 0.906.

Since the test statistic does not exceed the critical value, we fail to reject the null hypothesis. That is, there is not convincing evidence that there is a difference in the proportion of all men and the proportion of all women in this city who intended to vote for Trump at the 0.05 significance level.

Let the vector v have an initial point at (1,−1) and a terminal point at (7,2) what is the direction angle?

Answers

The direction angle of the vector with initial point (1, -1) and terminal point (7, 2) is approximately 26.57 degrees, found by calculating the arctangent of the ratio of the y and x components of the vector.

The direction angle of the vector v is the angle it makes with the positive x-axis, measured counterclockwise.

To find this angle, we need to calculate the difference between the y-coordinates and x-coordinates of the terminal and initial points of the vector, respectively. Then, we can use the arctangent function to find the angle.

Let's first find the components of the vector v

v = <7 - 1, 2 - (-1)> = <6, 3>

Now, we can find the direction angle as follows

θ = arctan(3/6)

θ = 0.4636 radians (in decimal form)

The new coordinates of dilated rectangle by scale factor of 1/4 are J(1, 2), K(3, 2), L(3, 1), and M(1, 1) we can draw figure.

We are given the coordinates of the vertices of a rectangle J(4,8), K(12,8), L(12,4), and M(4,4).

To dilate the rectangle by a scale factor of 1/4, we need to multiply each coordinate by 1/4.

Multiplying each x-coordinate by 1/4

x-coordinate of J: 4 * 1/4 = 1

x-coordinate of K: 12 * 1/4 = 3

x-coordinate of L: 12 * 1/4 = 3

x-coordinate of M: 4 * 1/4 = 1

Multiplying each y-coordinate by 1/4

y-coordinate of J: 8 * 1/4 = 2

y-coordinate of K: 8 * 1/4 = 2

y-coordinate of L: 4 * 1/4 = 1

y-coordinate of M: 4 * 1/4 = 1

Therefore, the coordinates of the dilated rectangle are: J(1,2), K(3,2), L(3,1), and M(1,1).

Using these new coordinates, we can draw the dilated rectangle by plotting the four vertices on a coordinate plane.

The dilated rectangle has the same shape and orientation as the original rectangle, but it has been reduced in size by a scale factor of 1/4.

find the inverse of the function f(x)=-1/25x^2, x<0

Answers

The function is :

[tex]f(x) =\frac{-1}{25x^{2} },x < 0[/tex] the inverse function is:

Inverse function: [tex]f^-^x(x)=-\frac{\sqrt{\frac{-1}{x} } }{5}[/tex]

Domain: (-[tex]\infty[/tex],9]

Range: [tex](-\infty,0][/tex]

What is an inverse function ?

If the inverse function of f is the function g, then x = f(x) gives x = g(y). We just need to reverse the function.

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1. One should not confuse (-1) with exponent or reciprocal here.

If f and g are inverse functions, then f(x) = y if and only if g(y) = x

The function is :

[tex]f(x) =\frac{-1}{25x^{2} },x < 0[/tex]

We have to find the inverse of the function.

The inverse, interchange the variables solve for y,

Now,

[tex]f(x) =\frac{-1}{25x^{2} },x < 0[/tex]

[tex]f^-^x(x)=\frac{\sqrt{\frac{-1}{x} } }{5}[/tex]

So, [tex]f^-^x(x)=-\frac{\sqrt{\frac{-1}{x} } }{5}[/tex]

Hence,

For the given rectangular equation give its equivalent polar equation

Answers

Answer:

The last option

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

Step-by-step explanation:

Given equation is 6x - y = 14

To convert an equation in rectangular(cartesian) form, f(x, y) to polar f(r, θ) we use the following information

x = rcosθ

y = rsinθ

Substituting for x and y in the original rectangular equation 6x - y = 14,

6(rcosθ) - rsinθ = 14

Factoring out r on the left side,
r(6cosθ - sinθ) = 14

which gives

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

The dot plots

From the dot plots, we can see that the data are normally distributed

This means that the mean, the median and the mode are equal

From the distribution of the random variable, we have the following readings

mean = 80

Hence, the estimate of the population mean is 80

The variability in the distribution

Here, we use the range

So, we have

Variability = Highest - Least

This gives

Variability = 140 - 20

Variability = 120

A man is flying in a hot air balloon in a straight line at a constant rate of 5' per second while keeping it at a constant altitude. As he approaches the parking lot of a market. , he notices that the angle of depression from his balloon to a friend's car in the parking lot is 34゚. A minute and a half later after flying directly over his friend's car, he looks back to see his friend getting into the car and observes the angle of depression to be 36゚ At that time what is the distance between him and his friend?​

Answers

The distance is given as 272.98 feet.

What is Angle of Depression?

The measurement of the angle of depression relates to the formation between a horizontal line and the observer's sightline to an object or point that exists beneath their level.

Therefore, it demonstrates the formed degree between the observer's line of vision towards a subject and the horizontal flatness visible when looking downwards at it from afar.

This notion is prevalent throughout trigonometry and play a vital role in areas including surveying, navigation and architecture. The degrees obtained from this practice are generally calculated via angles, with a complete 90-degree measure indicative of viewing straight downward over the designated target.

Factor cards is a one - player game using numbered cards. To begin with, all cards are in a central pile with their numbers visible. At each turn , exactly one card is moved from the central pile to the score pile and one or more cards are moved from central pile to the discard pile according to these rules.
Rule 1: A card may be moved to the score pile only if the number on the card has at least one of its factors, other than itself, still on the central pile.
Rule 2: When a card is moved to the score pile, all the cards that have factors of its number and are still in the central pile are moved to the discard pile.
Play stops when no card in the control pile has a factor other than itself in the central pile. The players score is the sum of all numbers on the cards in the score pile at the end of play.
In the following questions, the game starts with 20 cards numbered 1 to 20 and are therefore called 20-games.
A) Show steps that will produce a score of more than 100 points in a 20- game
B) What is the maximum score for a 20- game. Explain why it is the maximum
C) Explain why every 20- game ends with 8 or fewer cards in the score pile .

Answers

The match terminates as soon as the central heap runs out of cards whose factor are not present elsewhere, resulting in a score of 92 - falling short from 100.

How to explain the information

It should be noted that to acquire a higher point achievement, alternative approaches can be tested; however, reaching beyond the hundred mark is not guaranteed.

Conversely, with each 20-game, the final outcome should contain 8 or fewer pieces in the tally pile since there are strictly 17 cards eligible to be shifted into this collection. Subsequently, due to the 138 maximum points potential (stated in part B), and the entire set amounting for 210 points - the minimum count for items within the discard pool will be 3 (as calculated from 20 - 17).

If x and y vary directly and y is 2 when x is 3, what is why when x is 2

Answers

Step-by-step explanation:

Direct variation means    y = k x

when y = 2      x= 3

   2 =  k *3

   2/3 = k

so the variation becomes y = 2/3 x
