You find this value by factoring. Factoring finds the zeros of the function. When the ball hits the ground, it has 0 height. Therefore, when the function goes through the x axis, it has a y value of 0. That means that when y = 0, the ball has hit the ground. Use the quadratic formula to factor
. Notice I rearranged the terms. When you factor that you get zeros of -3.19 and 2.19. The two things in math that will never EVER be negative are time and distance/length. Therefore, that tells us that the ball hits the ground 2.19 seconds after it was thrown.
Answer:
The answer is 9

729/27^4/3
Answer:
C
Step-by-step explanation:
N = 5 because there is already 4 terms and we are trying to find the 5th
39 + 7 = 46
So our expression has to equal 46.
C. 18 + 7(5- 1)
18 + 7 x 4
18+ 28
=46
