If ΔP′QR′ is a dilated image of ΔPQR, find the scale factor (k) and then find the value of x. answers: A) 7 B) 10.7 C) 6 D) 73.5

Black_prince [1.1K]

Answer:

see explanation

Step-by-step explanation:

To find k, calculate the ratio of corresponding sides, image to original, that is

k = $\frac{P'R'}{PR}$ = $\frac{8}{28}$ = $\frac{2}{7}$

Thus

QR' = $\frac{2}{7}$ × QR = $\frac{2}{7}$ × 21 = 2 × 3 = 6 , that is

x = 6 → C

What is the value of f(15) for the given function? What does this value mean in the context of the situation you described in pa

bija089 [108]

Answer:

$f(15)=525\ ft^{2}$

f(15) is the area of the rectangular garden for a width of 15 ft

Step-by-step explanation:

we know that

$f(x)=x(2x+5)$

where

x----> is the width of the rectangular garden

(2x+5) ----> is the length of the rectangular garden

f(15) -----> is the value of f(x) for x=15 ft

That means

f(15) is the area of the rectangular garden for a width of 15 ft

substitute the value of x and solve

$f(15)=15(2(15)+5)$

$f(15)=525\ ft^{2}$
