A ball is thrown vertically upward from the top of a building 144 feet tall with an initial velocity of 128 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s = 144 + 128 - 16t^2. (A) After how many seconds does the ball strike the ground?
(B) After how many seconds will the ball pass the top of the building on its way down?

sorry i just need to anwers this to get points

step-by-step explanation:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
