Which of the following is the scaling factor a of the function f(x)=3|x|?A. -1
B. -3
C. 1
D. 3

Answers

Answer 1

Answer: The scaling factor of the given function, f(x) = 3|x| is equal to 3. This is evident because the equation suggests that whatever is the absolute value of x from the equation is, multiply it only by 3 and then we determine the value of y. The answer to this question is letter D. 3.

Y = 22.56 cm

Step-by-step explanation:

To find the diameter Y of the circle we must first find the radius of the circle

Area of a circle = πr²

where

r is the radius

From the question

Area = 400cm²

Substitute the value into the above formula and solve for the radius

That's

400 = πr²

Divide both sides by π

We have

${r}^(2) = (400)/(\pi)$

Find the square root of both sides

$r = \sqrt{ (400)/(\pi) }$

radius = 11.28 cm

Since we have the radius we can use it to find the diameter Y using the formula

diameter = radius × 2

radius = 11.28

Y = 11. 28 × 2

We have the final answer as

Y = 22.56 cm

Answer: X = 1/2(y)

Z= 3/4(x)

But x= 1/2(y)

So z = 3/4 * 1/2(y)

Z = 3/8(y)

Total= 1/2(y) +3/8(y) + 1/8(y)
