At a fourth of july celebration, a rocket is launched straight up with an initial velocity of 128 ft. The height of the rocket in feet above sea level is modeled by the expression 128t - 16t^2, where T is the time in seconds after the rocket is launched. (a) what is the gcf of each term of the expression? (b) write the factored form of the expression for the height of the rocket after T seconds. (c) well the height of the rocket be greater after four seconds or after six seconds?

Step-by-step explanation:

Given

Height of the rocket is given by

(a)Greatest common factor in each term is

(b)

(c)

After

after

Thus after height of rocket is greater .

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
