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: meh
Step-by-step explanation:
The answer is <span>B.The statement is true, but the inverse is false.
An acute angle is less than 90 degrees when talking about the terminal side. It inverse would be 360 - 43 = 317 degrees </span>
Answer:
A=0.83 cube root
Step-by-step explanation:
V^3=90=(6*A)^3
so A^3=90/6^3=90/108
so A = 0.83 cube root
The shaded area ( the top)= the area of the base
It would be 4x < h < 10x
the difference between 3x - 7x =4
and the sum would be 3x + 7x =10
