Rectangle N has an area of 5 square units. James drew a scaled version of Rectangle N and labeled it Rectangle P. What scale factor did James use to go from Rectangle N to Rectangle P? (rectangle p's area is 45)

The scale factor James used to go from Rectangle N to Rectangle P is 3 or 3:1

Step-by-step explanation:

Given that Rectangle N has an area of 5 square units. That is An = 5

Rectangle P has an area of 45 square units. That is Ap = 45

 The scale factor James used to go from Rectangle N to Rectangle P will be in the form

An/Ap = N^2/P^2

Where N and P are the factors

(N/P)^2 = 5/45

N/P = sqrt root (1/9)

N/P = 1/3

Cross multiply

P = 3N

The scale factor James used to go from Rectangle N to Rectangle P is therefore equal to 3 or 3:1

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
