For any number n>1, is (0.7 + 0.7i)n

a. Greater than 1?

b. Less than 1?

C. Equal to 1?

Using complex numbers, it is found that the correct option regarding the expression is:

a. Greater than 1.

Complex numbers are numbers that have a real and an imaginary part, and are modeled by:

In which:

The magnitude of the number is:

In this problem, the number is:

The smallest possible value is n = 4, hence:

And the magnitude is:

Which is greater than 1, hence option a is correct.

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,
