Answer:
Part a) to find the maximum height of the snowball, you have to differentiate the function. Therefore you get ----> dh/dt= -32x-8 . Now equate this to zero and solve for x. x= (-1)/4 now sub this value in to find h(x) [note: i'm talking about the original function] . I got h max = h((-1)/4) = 9 which is the max height.

Answer: Choice C</h3>
Explanation:
The x intercepts or roots are x = 3 and x = 5, which lead to the factors x-3 and x-5 respectively.
Multiplying out those factors gets us this:
(x-3)(x-5)
x(x-5)-3(x-5)
x^2-5x-3x+15
x^2-8x+15
Answer:
x = -6
Step-by-step explanation:
Solve:
4x = 1/3(6x - 30) - 2
4x = 2x - 10 - 2
2x = -10 - 2
2x = -12
x = -6
Check:
4(-6) = 1/3(6(-6) - 30) - 2
-24 = 1/3(-36 - 30) - 2
-24 = 1/3(-66) - 2
-24 = -22 - 2
-24 = -24
