Answer:

4 1/3

Step-by-step explanation:

First, add all three numbers together. Then, divide that number by three, because there were three numbers to begin with. If you put this into a calculator, you will get 4.33333333... because 1/3 is equal to 0.333333333. This is useful to know because then when you get 0.6666666 you know that it is 2/3. Anyway, your answer is 4 1/3.

An object is thrown from a platform. Its height (in meters), x seconds after launch, is modeled by h (x) = -5 (x + 1) (x -9)

Answer:

Step-by-step explanation:

This is already factored for us, which is really nice, so now all we need to do is apply the Zero Product Property to the sets of parenthesis and solve for x, which will give us the 2 times that the object is on the ground.

x + 1 = 0 so

x = -1

x - 9 = 0 so

x = 9

We all know that time cannot ever be negative, so the time that the object is on the ground is 9 seconds after it's launched (which was from an initial height of 45 meters).
