Acomplex number z = a + bi has an absolute value of 3.28. what could the values of a and b be?

a could be equal to 1

b could be equal to 3.1238

Explanation:

The absolute value of a complex number is calculated as follows:

a + bi =

Now, we are given that:

complex number is ............> z = a + bi

absolute vale ..........> 3.28

This means that:

= 3.28

Square both sides:

a² + b² = (3.28)²

a² + b² = 10.7584

Since we have one equation in two unknowns, therefore, we need to assume one of the variables and solve for the other.

Assume a = 1:

1 + b² = 10.7584

b² = 9.7584

either b = 3.1238

or b = -3.1238

Based on the above, one of the possible solutions is:

a = 1

b = 3.1238

You can assume any other value for the a and solve for b.

Hope this helps :)

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
