Answer:
B: y = 2x² - 16x + 40
Step-by-step explanation:
You can find this simply by expanding the given function:
y = 2(x - 4)² + 8
y = 2(x² - 8x + 16) + 8
y = 2x² - 16x + 32 + 8
y = 2x² - 16x + 40
9x=180
X= 20
Largest 4x 4(20) = 80 degrees
Answer:
3 : 5
Step-by-step explanation:
Given 2 similar figures with linear scale factor = a : b , then
ratio of areas = a² : b²
Here ratio of areas = 9 : 25 , thus
linear ratio =
:
= 3 : 5
