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.
An obtuse angle is 130 degrees. Any angle more than 90 degrees is obtuse, any angle under 90 degrees is acute, and 90 degrees is a right angle<span>.</span>
