What is Pythagoras Rule?

You should be aware that the Pythagoras' Theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The given sides are

AC = 8.5 inches

BC = 11 inches

AB = x

Using the Pythagoras rule we have

x² = 11² + 8.5²

x² = 121 + 72.25

x² = 193.25

x = √193.25

x = 13.9 inches

Therefore AB = 13.9 inches

3  The sine and cosine ratios for angles A and B are

Sine A = opposite/Hypotenuse

Sin A = 11/13.9

Sine A = 0..7914

A = Sin⁻¹0.7914

The ratio cos B = Adjacent /Hypo

Cos B = 8.5/13.9

Cos B = 0.6115

B = Cos⁻¹0.6115

Submit Answer

Answers

To find the daily production number that yields a minimum cost, we need to find the value of x that minimizes the cost function C(x) = 800 - 50x + 0.25x^2.

We can find the minimum point of the quadratic function by using the formula:

x = -b/(2a)

where a = 0.25, b = -50.

Substituting these values into the formula, we get:

x = -(-50)/(2*0.25)
x = 100

Therefore, the daily production number that yields a minimum cost is 100 fixtures.

Answers

Answer:

Step-by-step explanation:

3.1:

Using the compound angle expansion, we have:

sin 2x = sin(x + x) = sin x cos x + cos x sin x

sin 2x = 2 sin x cos x

Therefore, sin 2x = 2 sin x cos x.

3.2:

Using the result from 3.1:

3.2.1: sin 100° = 2 sin 50° cos 50° = sin 100° = 0.766

3.2.2: sin 46° = 2 sin 23° cos 23° = sin 46° = 0.719

3.2.3: sin 40° = 2 sin 20° cos 20° = sin 40° = 0.642

3.3:

Using the identity sin(a ± b) = sin a cos b ± cos a sin b:

3.3.1: 2 sin 19° cos 19° = sin 38° = sin (45° - 7°) = sin 45° cos 7° - cos 45° sin 7° = (1/√2)cos 7° - (1/√2)sin 7° = -sin (7° - 45°) = -sin 38°

Therefore, 2 sin 19° cos 19° = -sin 38°.

3.3.2: 2 cos 40° sin 40° = sin 80° = sin (45° + 35°) = sin 45° cos 35° + cos 45° sin 35° = (1/√2)cos 35° + (1/√2)sin 35° = sin (35° + 45°) = sin 80°

Therefore, 2 cos 40° sin 40° = sin 80°.

3.3.3: sin 25° cos 155° = (1/2)(sin 180°) = 0

Therefore, sin 25° cos 155° = 0.

Given matrix, where we have to find out, is the game strictly determined for the following matrix or not?

[tex]\left[\begin{array}{ccc}-7&7&-3\\3&8&6\\1&3&-3\end{array}\right][/tex]

Using the minimax theorem, we know that if the game is strictly determined, the value of the game is equal to the value of the saddle point. If the game is not strictly determined, the value of the game may not exist or may be a range of values.

We can check each row and column for minimum and maximum values:

The minimum value in the first row is -7.

The maximum value in the second column is 7.

The minimum value in the third row is -3.

We can see that the element in the first row and second column is both the minimum in its row (-7) and the maximum in its column (7), so it is a saddle point. Therefore, the game is strictly determined and the value of the game is -7.

Find the savings plan balance after 6 months with an APR of 2% and monthly payments of $150.

The balance is $.
(Do not round until the final answer. Then round to the nearest cent as needed.)

Answers

The savings plan balance after 6 months with an APR of 2% and monthly payments of $150 is approximately $913.35.

What distinguishes nominal interest rates from effective interest rates?

The stated interest rate on a loan or investment is known as the nominal interest rate; it does not account for compounding or any other elements that may have an impact on the real return or expense. Often, it is stated as an annual percentage rate (APR).

The effective interest rate, in contrast, takes into account compounding and other elements that may have an impact on the true cost or return of a loan or investment. It is often represented as an annual percentage yield and represents the actual rate of return or cost that is earned or paid on the principal amount over a certain time (APY).

Given that,

APR = 2% and monthly payments = $150.

For future value of annuity we use the following formula:

FV = Pmt × [(1 + r)⁽ⁿ⁻¹⁾] /r

Substituting the values:

r = 0.02/12 = 0.0016667, n = 6, and Pmt = $150:

FV = $150 × [(1 + 0.0016667)⁽⁶⁻¹⁾]/0.0016667

FV ≈ $913.35

Hence, the savings plan balance after 6 months with an APR of 2% and monthly payments of $150 is approximately $913.35.

the time taken to fill a tank was 2 hours and 43 minutes. write this time to the nearest 5 minutes

Answers

Answer:

To write the time taken to fill a tank to the nearest 5 minutes, we first need to convert 2 hours and 43 minutes to minutes. 2 hours = 2 x 60 = 120 minutes So, the total time taken in minutes is: 120 + 43 = 163 minutes To round this to the nearest 5 minutes, we need to consider the last digit of the number of minutes, which is 3. Since 3 is less than 5, we round down to the nearest multiple of 5, which is 160. Therefore, the time taken to fill the tank to the nearest 5 minutes is: 2 hours and 43 minutes = 160 minutes = 2 hours and 40 minutes

Final answer:

To write the given time to the nearest 5 minutes, round down the minutes value if the last digit is less than 5, and keep the hours value as it is.

Explanation:

To write the given time to the nearest 5 minutes, we need to round it to the closest multiple of 5. The given time is 2 hours and 43 minutes. To round to the nearest 5 minutes, we look at the last digit of the number of minutes, which is 3. Since 3 is less than 5, we round down the minutes to 0 and keep the hours as it is.

Write down an expression in terms of y, for john’s age.

Answers

Answer:

therefore, the expression for John's age in terms of y is 4y - 16.

Step-by-step explanation:

Answer:

John's age = 4y - 16

Step-by-step explanation:

We can start by using the information given to write expressions for the ages of Libby and John in terms of Alfred's age y.

We know that Libby is 4 years younger than Alfred, so her age can be written as:

Libby's age = Alfred's age - 4

We also know that John is 4 times as old as Libby, so his age can be written as:

John's age = 4 × Libby's age

Substituting the expression for Libby's age from the first equation into the second equation, we get:

John's age = 4 × (Alfred's age - 4)

Simplifying this expression, we get:

John's age = 4 × Alfred's age - 16

Therefore, an expression in terms of y for John's age is:

John's age = 4y - 16

Kremena took out a $500 discounted loan for a period of 3 months. The amount she actually received into her bank account was $460. Assuming simple interest rates, what is effective interest rate re?

Answers

The effective interest rate on the loan is also 32%.

What is effective interest rate ?

Effective interest rate is the actual interest rate that is paid or earned on an investment, loan, or other financial product. It takes into account not only the nominal interest rate, which is the stated rate of interest, but also the frequency of compounding or other factors that affect the overall return.

According to the question:
To find the effective interest rate, we first need to calculate the amount of interest Kremena paid on the loan. We can do this by subtracting the amount she received from the amount of the loan:

Interest = Loan amount - Amount received

Interest = $500 - $460

Interest = $40

Next, we can use the formula for simple interest to calculate the interest rate:

I = P * r * t

where I is the interest, P is the principal (loan amount), r is the interest rate, and t is the time in years.

Since Kremena took out the loan for 3 months, which is a quarter of a year, we have:

I = P * r * t

$40 = $500 * r * (3/12)

$40 = $500 * r * 0.25

r = $40 / ($500 * 0.25)

r = 0.32 or 32%

So the interest rate on the loan is 32%. However, this is the nominal interest rate, which does not take into account the effects of compounding. To find the effective interest rate, we need to take into account the fact that Kremena only received $460, which means that she effectively paid more interest than she would have if she had received the full $500.

To calculate the effective interest rate, we can use the formula:

[tex]re = (1 + r/n)^n - 1[/tex]

where re is the effective interest rate, r is the nominal interest rate, and n is the number of compounding periods per year. Since the problem specifies simple interest, there is no compounding, so we can take n = 1. Plugging in the values, we get:

[tex]re = (1 + 0.32/1)^1 - 1[/tex]

re = 0.32 or 32%

So the effective interest rate on the loan is also 32%.

Check the picture below.

The length of the hypotenuse (x) in the given right triangle is approximately 10 units.

Hence the correct option is B.

Given is right triangle with perpendicular side having measurement of 5 units,

The acute angle between the base and the hypotenuse = 30°

The acute angle between the perpendicular and the hypotenuse = 60°

We need to find the length of the hypotenuse (x).

We can use the trigonometric ratio for sine (sin) to relate the lengths of the sides.

In this case, we'll use the sine of the 30° angle:

sin(30°) = opposite/hypotenuse

sin(30°) = 5/x

To solve for x, we can rearrange the equation:

xsin(30°) = 5

x = 5 / sin(30°)

Now, we can calculate the value of x using this equation:

x = 5 / sin(30°)

x ≈ 10 units

Therefore, the length of the hypotenuse (x) in the given right triangle is approximately 10 units.

A retailer sold bat at 25% profit. Cost price of 5 bats is equal to cost price of 4 balls. On ball retailer earns 40% profit. If on selling one bat and one ball he earns Rs. 45 profit then find cost price of ball

Answers

The cost price of one ball is equal to Rs. 75

How to evaluate for the cost price of ball

We shall represent the cost price of one bat with the letter 'x', so that the selling price of one bat is 125% of 'x', which is 1.25x.

The cost price of 5 bats is equal to the cost price of 4 balls. So,

5x = 4y, where 'y' is the cost price of one ball.

y = (5/4)x

Also, we know that the profit percentage on one ball is 40%. So, the selling price of one ball is 140% of its cost price, which is 1.4y.

Profit earned on selling one bat and one ball is calculated as:

Profit = Selling price - Cost price

Profit = (1.25x + 1.4y) - (x + y)

Profit = 0.25x + 0.4y

Profit = 0.25x + 0.4(5/4)x {Substituting the value of 'y'}

Profit = 0.75x

given that the above profit is equal to Rs. 45. them,

0.75x = 45

x = 60

The cost price of one bat is Rs. 60 and the cost price of one ball:

y = (5/4)x

y = (5/4) × 60

y = 75

Therefore, the cost price of one ball is Rs. 75.

i need help with question 9

Answers

Answer:

Option D

Step-by-step explanation:

Total number of posters Rhett puts up = 9

                Printing cost of each poster = $2

                                    ∴Total cost on posters = ([tex]\frac{2 dollars}{1 poster}[/tex]) × (9 posters)

                                                                           = $18

Note: The unit multiplier used above is arranged in a way that the current unit of “posters” is cancelled out and the answer is assigned with the new unit of “dollars".

Number of fliers Rhett gives out = x

Printing cost of each flier = $0.20

                                    ∴Total cost on fliers = [tex]\frac{0.20 dollars}{1flier}[/tex] × (x fliers)

                                                                      = $0.20x

Note: The unit multiplier used above is arranged in a way that the current unit of “fliers” is cancelled out and the answer is assigned with the new unit of “dollars


∴How much it cost Rhett to search for his lost puppy:

y = Total cost on fliers + Total cost on posters

∴[tex]y = 0.20x + 18[/tex]

∴Option D

b. The formula that can be used to solve triangle CDE is the Law of Sines

c.

∠ e = 11

c = 75.47

d = 8.77

How to vertical height of the ladder

b. To find the vertical height of the ladder that is touching the wall, we use the trigonometric function

sin 65 = vertical height / height of ladder

sin 65 = vertical height / 20

vertical height = sin 65 * 20

vertical height = 18.13 feet

c. The given angle 65° is the angle of elevation.

d. To find how far the foot of the ladder is from the wall, we can use the trigonometric function cosine.

cos 65° = x / 20

x = 20 cos 65°

x ≈ 8.45 feet

7. The statement is true. The angle of elevation is the angle between the horizontal line and the line of sight from the observer to the object above the horizontal line.

The angle of depression is the angle between the horizontal line and the line of sight from the observer to the object below the horizontal line.

If the two objects are on parallel lines (e.g., the ground and a bridge above it), then the angle of elevation from one object is congruent to the angle of depression from the other object.

8. a. Diagram of triangle CDE is attached

b. The formula that can be used to solve triangle CDE is the Law of Sines

∠ e = 180 - 52 - 17 = 111

sin E / 28 = sin C / c = sin D / d

c = 28 sin 52 / sin 111 = 23.63

d = 28 sin 17 / sin 111 = 8.77

Jose measures the diameter of a ball as 15 inches. How many cubic inches of air can the ball hold, to the nearest tenth?

Answers

Answer:

Assuming the ball is a perfect sphere, we can use the formula for the volume of a sphere to calculate the amount of air it can hold.

The formula for the volume of a sphere is:

V = (4/3)πr^3

where V is the volume, π is a mathematical constant approximately equal to 3.14, and r is the radius of the sphere.

To calculate the radius of the ball from its diameter of 15 inches, we divide by 2:

r = d/2 = 15/2 = 7.5 inches

Substituting this value into the formula, we get:

V = (4/3)π(7.5)^3 ≈ 1767.15 cubic inches

Therefore, the ball can hold approximately 1767.15 cubic inches of air to the nearest tenth.
