The functions below represent the cost some homeowners pay for water and sewer usage. This is based on the number of 100-gallon units of water used, defined by x. Water usage:
W(x)= 0.129x

Sewer usage:
S(x) =0.158x + 16.22

Based on this information, what is the total amount a homeowner will pay if the water and sewer usage for one month is 3800 gallons?

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
