A water balloon is dropped from the top of a building 64 feet above the ground. The equation
h(t) = -16t2 + 64 can be used to model the descent of the water balloon.
a. What are the x-intercepts of the function?

b. Interpret the meaning of the x-intercepts in context of the situation

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

r and t.

both are 64 degrees.

a.)the line for function b is steeper
