Answer:
The formula is: y = y•e^(-k•x)
In this specific case the function is: 512•e^(-x/1.44)

Answer:
Step-by-step explanation:
Inverse variation satisfies the form yx=k, if y=2 while x=-6 then
2(-6)=k, k=-12, then
yx=-12, when y=-3
-3x=-12
x=4
He will use 7 pegs in total to hang 6 t shirts in line
38+0.11m=51+0.09m
0.02m=13
m=650 miles
If Austin will drive more than 650 miles he can choose the second plan of car renting.
If he plan todrive less than 650 miles then it's more preferable to choose the first plan of car renting
