Question 13 (2 points)Find the area of the Sector of a circle with the given angle. Round your answer to the nearest tenth.3158
olasank [31]

13

Answer: 175.8 cm^2

Explanation:

The formula for calculating the area of a sector is expressed as

Area = θ/360 x πr^2

where

r is the radius of the circle

θ is the angle subtended at the center

From the information given,

θ = 315

r = 8

π = 3.14

By substituting these values into the formula,

Area of sector = 315/360 x 3.14 x 8^2

Area of sector = 175.8 cm^2

Which of the following describes the graph of y=\sqrt[3]{8x-64}-5 compared to the parent cube root function?
andriy [413]
Answer: stretched by a factor of 2 and translated 8 units right and 5 units down

Explanation:

These is the set of choices that accompany with this question:


<span>a) stretched by a factor of 2 and translated 64 units right and 5 units down
b) stretched by a factor of 8 and translated 8 units right and 5 units down
c) stretched by a factor of 2 and translated 8 units right and 5 units down
d) stretched by a factor of 8 and translated 64 units right and 5 units down


Solution:

</span>Let's work a little the given function to compare it with the parent function.

1) The given function is y = ∛[8x - 64] - 5

2) Extract common factor 8 of the expression inside the square brackets:

y = ∛[ 8( x - 8) ] - 5

3) Extract 8 from the root:

y = 2∛(x - 8) - 5

4) The parent function is ∛x. Call the parent function g(x) => g(x) = ∛x

5) Compare: y is 2 * g(x - 8) - 5

6) Analyze the meaning of that:

g(x - 8) means that the graph of the function is translated 8 units to the right

scaling by 2 means that the graph is stretch vertically (by a scale factor of 2)

- 5 means that the entire graph is shifted 5 units downward.

So, the description of the graph y = ∛(8x - 64) - 5 compared to the parent cube root function is: stretched by a factor of 2 and translated 8 units right and 5 units down
