Answer: 
====================================================
Work Shown:
The trick here is to first simplify the expression so that the 
term in the very lower denominator cancels out. This is to avoid dividing by zero. Once this division by zero error is avoided, we can replace the delta x term with 0 and evaluate the limit as approaches 0 from the right or positive direction.
Answer: 20% is your answer
Step-by-step explanation:
180-150=30
30 divided by 150 = .2 which is 20%
-16t^2+16t+192= 0 (when the ball hits the ground, h will be zero)
Use the quadratic formula to solve the equation (If you don't know how to solve quadratic equations, just ping me dude and I'll try my best to help you)
We get x=-3 and 4
Now since time can't be negative, therefore the answer is after 4 seconds
Answer:
x > 2
(in the graph, the x value does not go below 2.)
