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
$3.15
11 quarters = $2.75
4 dimes = $0.40
$0.40+$2.75=$3.15
Most likely rates, percents and ratios at a higher level. Also, multiplication and division of fractions at a higher level.
Answer:
50
Step-by-step explanation:
20/2 is 10 so 10x5 is 50
