Step-by-step explanation: 4.5% of 63.20
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
Answer:
$45.8
Step-by-step explanation:
32.06 / 14= 2.29
2.29x20=45.8
Stamps = 100, Postcards = 40
100 x 0.41 cents + 40 x 0.26 cents = $41 + $10.4 = $51.4
------ Solution-----
$0.41 x STAMPS + $0.26 x POSTCARDS = $51.4
1 STAMP = 20 + 2 x POSTCARDS
$0.41 x (20 + 2 x POSTCARDS) + $0.26 POSTCARDS = $51.4
POSTCARDS = 40
STAMPS = 20 + 2 x 40 = 100
