Jack is standing on the roof of his house in kicked a rubber ball in the air for it to land on the ground for his dog Henry to fetch. The ball is launched into the air from a height of 12 feet at time t=0. The function that models the situation is h(f) = -2t^2 + 10t +12, where T is measured in seconds and H is the height in feet

When will the ball hit the ground

1. List all needed information from the problem

2. Restate the question and you’re all words what is it asking you to find (not just x)

3. What formulas and/or operations do you need to solve this problem ?

4. Explain what your variables in values are (if necessary)

5. Work out the problems using numbers and operations and explaining
( in words) all steps (include the words why and because properties)

6. Write your final answer in a sentence restating the question.

7. Why does your answer make sense.

The ball would hit the ground in 50 seconds, if you were to look at a graph also that can help you because it would be 50 marked on the graph also. If he hits the ball from 12 feet that would mean going by the equation you would need to find the range which means you would have to find the domain. You will the calculate the domain by your range.

Hope this helps!

the answer is 50

Step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
