Answer: 42.25 feet
Step-by-step explanation:
We know that after "t" seconds, its height "h" in feet is given by this function:
The maximum height is the y-coordinate of the vertex of the parabola. Then, we can use the following formula to find the corresponding value of "t" (which is the x-coordinate of the vertex):
In this case:
Substituting values, we get :
Substituting this value into the function to find the maximum height the ball will reach, we get:
Answer:
The savings were changed by $88
Step-by-step explanation:
1 backpack costs 8 dollars and they bought 8 of them, you have to multiply 8 dollars by 8 cause there is 8 backpacks which is 64 , pen and pencils for 1 backpack costs 3 dollars , so you have to multiply 3 by 8 cause there are 8 backpacks which is 24. then you add 64 and 24 which is 88
The answer is -34 k^8 z^12.
