Answer:
2s or 3s
Step-by-step explanation:
Given the function that models the height of the object as;
h(t) = - 16t^2 + 80t + 96
The ball reaches the ground when h = 0
Substitute
0 = - 16t^2 + 80t + 96
Divide through by -16
0 = t²-5t-6
t²-5t-6 = 0
t²-2t-3t+6 = 0
t(t-2)-3(t-2) = 0
(tt-2)(t-3) = 0
t - 2 = 0 and t-3 = 0
t = 2 and 3s
Hence it will take the ball 2s or 3s to reach the ground
Answer:
The volume of the dilated cube is 9375cm³. The volume of the original cube is 75 cm³. The scale factor for the dilation is 5. We multiply the volume of the original cube by 125 to obtain the volume of the dilated cube.

(f+g)(x) = f(x) + g(x)
x^2 + x + x + 2
= x^2 + 2x + 2
Final answer: x^2 + 2x + 2
Start by realizing that n*p = (-5)(-2) = 10.
The reason is because an even number of minus signs will give a plus. Since 2 minus signs are multiplied together, the answer is > 0. or plus.
10/np = 10/10 = 1 <<<< Answer
