Use inductive reasoning to determine the units digit of the number 3 to the 58 power

We must find a pattern in the powers of 3:

So, as you can see, both and end with 1. So, we can generalize as follows:

Since , we can deduce that ends with 9.

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,
