Answer:
6.
Step-by-step explanation:
To solve this, you can set up an equation as such:
x²-18= 3x
Now, rearrange this to make it an equation in standard form:
x²-3x-18=0.
Simply turn this equation into factored form:
(x-6)(x+3)= 0.
The only positive solution here is x=6.

Answer:
5.12 seconds to the nearest hundredth.
Step-by-step explanation:
When the ball hits the ground h = 0 so
-16t^2 + 81t + 5 = 0
t = [ -81 +/- sqrt ((81^2 - 4 * -16 * 5)]/ (2*-16)
= (-81 +/- sqrt 6881) / -32
= 5.12 , -0.6
So the answer is 5.123 seconds.
