Jamal throws a golf ball straight up from a height of 5 feet and at a speed of 75 feet per second. the height of the ball in feet is given by the polynomial
−16t^2 + 75t + 5, where t is the time in seconds. how high is the ball after 4 seconds?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
