Step-by-step explanation:
From y(t) = −16t^2 − 3t + 300 find at what time the fertilizer hits the ground (has height 0)
0 = −16t^2 − 3t + 300
Using the quadratic formula (minus b plus or minus the square root of b squared minus 2 a c over 2 a) you get
t = 4.237 seconds
So the horizontal distance is 85t = 85 * 4.237 = 360.145 feet
