Answer
Sarah’s graph is a vertical translation of f(x) = x².
Tammy's graph moved 9 units from f(x) = x² in a positive direction.
Sarah's graph has a y-intercept of 9.
Answer:
156 inches.
Step-by-step explanation:
All you have to do is add up all the side lengths. If one side is 28, the opposite side across from it will also be 28.
So, we just have to add 28 + 28 + 50 + 50 = 156
1) x² - 13x + 30 = 0
x² ⇒ x * x
-13x ⇒ -10x - 3x
30 ⇒ -10 * -3
(x-10) (x-3) = 0
x - 10 = 0 ⇒ x = 10
x - 3 = 0 ⇒ x = 3
Answer is Choice D:) x = 3 or x = 10
2. P(x) = 480x - 2x²
a) P(100) = 480(100) - 2(100²) = 48,000 - 20,000 = 28,000
b) P(120) = 480(120) - 2(120²) = 57,600 - 28,800 = 28,800
c) P(240) = 480(240) - 2(240²) = 115,200 - 115,200 = 0 THIS IS THE ANSWER.
