A ball is thrown vertically upwards from the top of a 96-foot tower with an initial velocity of 48 feet per second. Use the function s(t) = -16t 2 +v 0 t + s 0 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?

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

hi there!

the answer will be d: 2

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
