4/16. 1/4

5/16. 5/16

6/16. 3/8

7/16. 7/16

8/16. 1/2

Answer:

The sequence has a common difference of 1/16, which means to get the next term, we need to add 1/16 to the previous term.

The next four terms would be:

9/32 (1/4 - 1/16)

5/16 (1/4 + 1/16)

11/32 (5/16 + 1/16)

3/8 (11/32 + 1/16)

So the full sequence is: 1/16, 1/8, 3/16, 1/4, 9/32, 5/16, 11/32, 3/8, ...

Answer:

μ (∠1) = 82°

μ (∠2) = 98°

μ (∠3) = 82°

μ (∠4) = 98°

Step-by-step explanation:

As the vertically opposite angles are equal to each other,

μ (∠2) = μ (∠4)

   98° = 98°

As the angles in a straight line are added up to 180°,

μ (∠2) + μ (∠3) = 180

98 + μ (∠3) = 180

μ (∠3) = 180 - 98

μ (∠3) = 82°

As the vertically opposite angles are equal to each other,

μ (∠3) = μ (∠1)

   82° = 82°

The value of x that makes A parallel to B is 15.

Alternate exterior angles are a pair of angles that lie outside of two parallel lines and are on opposite sides of the transversal. In other words, they are a pair of non-adjacent angles that are formed when a transversal intersects two parallel lines. The angles are congruent, meaning that they have the same measure.

The term "alternate" refers to the fact that they are on opposite sides of the transversal and "exterior" indicates that they are outside of the parallel lines. Alternate exterior angles are important in geometry because they can be used to prove that two lines are parallel. If the alternate exterior angles are congruent, then the lines are parallel.

Since the alternate exterior angles are equal, we can set them equal to each other:

8x + 30 = 10x

Subtracting 8x from both sides, we get:

30 = 2x

Dividing both sides by 2, we get:

15 = x

So the value of x that makes A||B is 15.

For the first equation, we can complete the square to find its vertex form. Here's how we do it:

0 = x^2 - 18x + 1

0 = (x - 9)^2 - 80

So we have (x - 9)^2 = 80. This is in the form (x - p)^2 = q, where p = 9 and q = 80.

For the second equation, we can complete the square in a similar way:

x^2 + 26x + 167.5 = 0

x^2 + 26x = -167.5

x^2 + 26x + (26/2)^2 = -167.5 + (26/2)^2

(x + 13)^2 = 9.25

So we have (x + 13)^2 = 9.25. This is in the form (x - p)^2 = q, where p = -13 and q = 9.25.

Answer:

Put the point a tiny bit more than half way between 14 and 15.

Step-by-step explanation:

If you are allowed to use a calculator, put in sqrt215 and you get out 14.66, that goes a little bit more than halfway between 14 and 15.

If you are not allowed to use a calculator, think of the numbers on the numberline in terms of answers to *perfect square* questions.

So 12 is sqrt 144.

13 is sqrt 169.

14 is sqrt 196.

15 is sqrt 225.

So the 215 in your question is in between 196 and 225.

215 is closer to 225 (than to 196) so put the point closer to sqrt 225. That is, in between 14 and 15 and just a tad bit closer to 15.

Derrick invested $23,306.28 at 2.25% and $462.79 at 1.5%.

What is percentage?

Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%". For example, 50% means 50 out of 100 or 0.5 as a decimal.

Let's start by assigning variables to the unknown quantities in the problem. Let x be the amount Derrick invested at 2.25% and y be the amount he invested at 1.5%.

According to the problem, Derrick invested "1000 less than twice" the amount he invested at 2.25% at 1.5%. This means:

y = 2(0.0225x - 1000) = 0.045x - 2000

Now we can set up an equation based on the total income from the interest:

0.0225x + 0.015y = 510

Substituting the expression for y from the first equation, we get:

0.0225x + 0.015(0.045x - 2000) = 510

Simplifying and solving for x, we get:

0.0225x + 0.000675x - 30 = 510

0.023175x = 540

x = 23306.28

So Derrick invested approximately $23,306.28 at 2.25%. To find the amount he invested at 1.5%, we can substitute this value for x in the equation for y:

y = 0.045x - 2000 = 0.045(23306.28) - 2000 = 462.7856

So Derrick invested approximately $462.79 at 1.5%.

Therefore, Derrick invested $23,306.28 at 2.25% and $462.79 at 1.5%.

The credit card holder paid $720.27 in interest over the 12 months. Answer choice A, $720.27, is the correct answer.

What is simple interest?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

First, let's calculate the monthly interest rate by dividing the APR by 12:

11.99% / 12 = 0.99917%

Next, let's calculate the interest paid on the monthly balance for each of the 11 months before the final payment:

Month 1:

Interest = $7,568.19 x 0.99917% = $75.59

Month 2:

Balance = $7,568.19 - $350 - $75.59 = $7,142.60

Interest = $7,142.60 x 0.99917% = $71.38

Month 3:

Balance = $7,142.60 - $350 - $71.38 = $6,721.82

Interest = $6,721.82 x 0.99917% = $67.11

Month 4-11: (follow the same process as above)

Interest for Month 4: $63.82

Interest for Month 5: $60.51

Interest for Month 6: $57.17

Interest for Month 7: $53.80

Interest for Month 8: $50.41

Interest for Month 9: $47.00

Interest for Month 10: $43.56

Interest for Month 11: $40.11

Now, at the end of month 11, the cardholder has a balance of:

$7,568.19 - ($350 x 11) - $75.59 - $71.38 - $67.11 - $63.82 - $60.51 - $57.17 - $53.80 - $50.41 - $47.00 - $43.56 - $40.11 = $1,225.74

Finally, the cardholder pays off the remaining balance of $1,225.74 at the end of month 12. The interest charged for this month would be:

Interest = $1,225.74 x 0.99917% = $12.25

So the total interest paid by the cardholder over the 12 months is:

$75.59 + $71.38 + $67.11 + $63.82 + $60.51 + $57.17 + $53.80 + $50.41 + $47.00 + $43.56 + $40.11 + $12.25 = $720.27

Therefore, the credit card holder paid $720.27 in interest over the 12 months. Answer choice A, $720.27, is the correct answer.

The values of x that could make the triangle into different types of triangles are:

For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.

Right Triangle:

A triangle is a right triangle if it satisfies the Pythagorean theorem: a² + b² = c², where c is the longest side (hypotenuse).

6² + 8² = x²

36 + 64 = x²

100 = x²

x = 10

Acute Triangle:

A triangle is acute if the sum of the squares of the two shorter sides is greater than the square of the longest side. Since we already know that the right triangle has x = 10, we can choose a value for x that is less than 10 to form an acute triangle.

Let's take x = 9:

6² + 8² > 9²

36 + 64 > 81

100 > 81

Obtuse Triangle:

A triangle is obtuse if the sum of the squares of the two shorter sides is less than the square of the longest side. We can choose a value for x that is greater than 10 to form an obtuse triangle.

Let's take x = 11:

6² + 8² < 11²

Matt's typing speed increased by 18.75%.

Step-by-step explanation:

To find the percent increase, we can use the following formula:

percent increase = (new value - old value) / old value x 100%

Using this formula, we can calculate the percent increase in Matt's typing speed as follows:

percent increase = (38 - 32) / 32 x 100%

percent increase = 6 / 32 x 100%

percent increase = 0.1875 x 100%

percent increase = 18.75%

In the equation y = 10 - 0.1x, the coefficient 0.1 represents the slope of the line.

it represents the rate of change of y with respect to x, which is the amount by which y changes for every unit increase in x.

In this case, the slope is negative (-0.1), which means that as the number of minutes on hold (x) increases by 1 unit, the level of satisfaction (y) decreases by 0.1 units.

In other words, the longer a customer spends on hold, the lower their level of satisfaction is likely to be. The slope is a key parameter in the equation and provides valuable information about the relationship between the two variables.

To determine how long your retirement savings will last when withdrawing R2 500 at the beginning of every month, we need to use a financial formula called the future value of an annuity formula, which calculates the future value of a series of equal withdrawals made at regular intervals over a fixed period of time.

In this case, we want to calculate how many months it will take for your retirement savings to be depleted, given that you will be withdrawing R2 500 at the beginning of every month. The formula is:

n = [log(PMT/(PMT - r*PV))]/[log(1+r)]

where:

PMT = R2 500 (the regular payment you will make every month)

r = 7,10%/12 (the monthly interest rate, which is the annual rate of 7,10% divided by 12)

PV = R411 016 (the present value of your retirement savings)

Using the above values in the formula, we get:

n = [log(2500/(2500-((7.10%/12)*411016))))]/[log(1+(7.10%/12))]

n = 182.1

Therefore, it will take approximately 182.1 months, or 15.2 years, until you run out of money, assuming all other factors remain constant, and you withdraw R2 500 at the beginning of each month.

2 real zeros at x = - 2 , x = 1

Step-by-step explanation:

f(x) = x² + x - 2

to find the zeros let f(x) = 0 , that is

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x + 1 = 0 ⇒ x = - 1

there are 2 real zeros , x = - 2 and x = 1

Because the x2 term's coefficient is positive, the function will rise without  equation bound as x approaches infinity or negative infinity. As a result, no horizontal asymptote exists.

An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9".

The y-intercept of the equation y = (0,0) is the point on the line where it meets the y-axis and corresponds to the value of y when x equals 0. As a result, the equation y = 0's y-intercept is (0,0).

An equation's domain is the set of all possible values of x for which the equation is defined.

a) Because there are no constraints on the potential values of x, the domain of the equation y = x2 - 4x is all real integers.

b) The domain of the equation y = 1/(x-4) includes all real numbers except x = 4, which is undefined since division by zero is undefined.

c) Because the term within the square root must be non-negative, the domain of the equation y = sqrt(x-3)(x-4) is x >= 3.

As x approaches a specific value, the graph of the function approaches but never reaches vertical asymptotes. As the denominator of a rational function hits 0, they arise.

Because y = (x-3)(x-4) is not a rational function, it lacks vertical asymptotes.

A function's horizontal asymptote is a horizontal line that it approaches when x approaches infinity or negative infinity.

The dominant term in the formula as x gets extremely large or very tiny is x2, thus we can rewrite the equation as [tex]y = x2 - 7x + 12[/tex]  .
