A towns population went from 40,000 to 50,000. What was the percent of change in the population?

The percent of change in the population was of 25%.

Step-by-step explanation:

Percent change:

The percent change is given by the change multiplied by 100, and divided by the initial value.

A towns population went from 40,000 to 50,000.

Change: 50000 - 40000 = 10000

Initial value: 40000

10000*100/40000 = 25%

The percent of change in the population was of 25%.

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,

y=sec x is the correct answer
