A ball is thrown vertically upwards from the top of a 96-foot tower with an initial velocity of 58 feet per second. Use the function s(t) = -16t² +V(0)t + so where V(0) is the initial velocity and s(0) the initial height.(a) After how many seconds does the ball attain its maximum height? (b) What is the maximum height the ball attains? (c) After how many seconds does the ball return to the ground?

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
