B. you have to be ready to multiply all the numbers to get your answer.
First graph it
#1
Maximum height is the y coordinate of vertex
Max height
#2
Time is the x coordinate of vertex
#3

x intercepts are the solutions
Take it positive
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
You want to isolate the variable 'y'.

Subtract 10 to both sides:

Divide -3 to both sides:
Answer:
60,60,60
Step-by-step explanation:
Step-by-step explanation:
Would equal 12 if the parenthesis indeed equal the absolute value of -6 which is simply 6. 6 x 2 = 12. When you multiply by a negative number, it negates the answer, so -6 x 2 would be -12.
so
12 to the power of 2
