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).

4vir4ik [10]

Answer:

9

Step-by-step explanation:

Given that the sample size is 45 blocks

Let number of red blocks in the bag to be x

Then the probability of chosing a red block will be x/45

Given that the probability of choosing a red block is 1/5 then you can form the expression;

x/45 = 1/5 ---------------find the value of x  by performing cross multiplication

5x=45*1

5x/5=45/5

x=9

Answer

Julia put 9 red blocks in the bag.
