Alocal window company charges 0.50 per window plus a base fee of $20 per appointment. they can wash a maximum of 200 windows per appointment. let c represent the total cost of an appointment and w represent the number of windows washed. using correct and formal function notation, write a function that represents total cost as a function of windows washed.
identify the practical domain of this function by filling in the blanks below. minimum windows washed ≤ w ≤ maximum windows washed
practical domain: ≤ w ≤
identify the practical range of this function by filling in the blanks below.
minimum cost ≤ c(w) ≤ maximum cost
practical range: ≤ c(w) ≤

What we know:
Circle A has a center at (2,0) and a radius of 8
Circle A' has a center at (-1,5) and a radius of 3

What we need to find: 
we need to find the transformation from the center point of A to A' and the scale factor 

Circle A can be mapped to Circle A'
center point translation (x,y)⇒[(x+a),(y+b)]⇒(x-3, y+5)

2+a=-1                                      0+b=5
-2+2+a=-1-2                                  b=5
a=-3

scale factor is 3/8
8x=3
8/8x=3/8
x=3/8

A)(x, y) → (x - 3, y + 5); scale factor 3/8
