The slope would be 0
This is basically how you do it if you need more help let me know
Answer:
66
Step-by-step explanation:
57 x 2= 114
180-114= 66
X = 9
Move the 1 over to make it 3x = 28. The. 28/3 equals 9
If the ball hit the ground it means that its height is equal to 0. In order to find the time after the ball <span>will hit the ground, we need to find the solution of the equation h(x)=0 which is different to 0.
-4.9x^2+21.3x=0
x(-4.9x+21.3)=0
-4.9x+21.3=0
x=21.3/4.9 = 4.3469 seconds</span>
