Answer:
40
Step-by-step explanation:
dilated by a factor 8 => the area of a rectangle would be (8x8) times of the origin,
5/8 × (8x8) = 5/8 × 64 = 40 ft²

Step-by-step explanation:
Step-by-step explanation:
x² + 4x - 9
= (x + 2)² - 13
a = 2, b = -13.

Obtuse
Answer:
100feet
Step-by-step explanation:
Given the height reached by a dolphin expressed by the equation is h = -16t^2 + 80t. At maximum height, the velocity is zero, hence;
v(t) = dh/dt = -32t + 80
0 = -32t + 80
32t = 80
t = 80/32
t = 2.5secs
Substitute t = 2.5 into the height formula h = -16t^2 + 80t
h = -16(2.5)^2 + 80(2.5)
h = -100+200
h = 100feet
Hence the maximum height the dolphin jumps is 100feet
