P=44.6
P=a+b+√a^2+b^2=11+15+√11^2+15^2≈44.6
Answer:
a. y^ -1 = e^x +2
Step-by-step explanation:
y = ln (x-2)
Exchange x and y
x = ln (y-2)
Solve for y
Raise each side with a base of e
e^ x = e^(ln(y-2)
e^x = y-2
Add 2 to each side
e^x +2 =y
10x + 25 = $145
10x = $120
x =10
The number of poses is 10
