Answer:
t = -1, 2
Step-by-step explanation:
Step 1: Define
h(t) = -5t² + 5t + 10
Step 2: Factor
h(t) = -5(t² - t - 2)
h(t) = -5(t - 2)(t + 1)
Step 3: Find roots
0 = -5(t - 2)(t + 1)
0 = (t - 2)(t + 1)
t - 2 = 0
t = 2
t + 1 = 0
t = -1
Answer:
H^2 = P^2+ B^2
10^2 = 3x^2 +4x^2
100 = 9x^2 + 16x^2
100 = 25x^2
100 ÷ 25 = x^2
4 = x^2
x= 2
