Step-by-step explanation:
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>
Answer:
no, there is an infatuate amount of solutions
Step-by-step explanation:
1.2(2x-5)=2/5(2x-15)+1.6x
2.4x -6 = .8x -6 +1.6
2.4 -6 = 2.4-6
0=0 ( infatuate)
