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>
She will be 56 after 14 years from now

there is no s in the question please explain
Step-by-step explanation:
Answer:
The value of x could be 3
Step-by-step explanation:
2 x 3 = 6 + 1 - 4 = 3 which is less than 5
Answer:
Let's find out!
Step-by-step explanation:
So we have to set up an equation
Let x= # of ribbons that can be cut
Thus:

So, we cannot have 36/7 ribbons! It's not possible!
So we just simplify!

There we go! She can cut 5 ribbons off!
I'll let you figure out the last one!
Hope this helps!
P.S. Stay Safe!
