Suppose a projectile is launched from a tower into the air with an initial velocity of 48 feet per second. Its height, h, in feet above ground is modeled by the function
h= -16t2 + 48t + 64 where t is the time, in seconds, since the projectile
is launched. How long was the projectile in the air?

Find the value of p for which the polynomial 3x^3 -x^2 + px +1 is exactly divisible by x-1, hence factorise the polynomial

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)
