How can you make your answer (41-13i)/(25) into a+bi form?
KengaRu [80]

Hello, do you know that for any a, b and c real numbers with c different from 0 the following is correct?

\dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}

Then,

\dfrac{41-13i}{25}=\dfrac{41}{25}-\dfrac{13}{25}i

So,

a=\dfrac{41}{25}\\\\b=\dfrac{-13}{25}

Thank you.

A county has a population density of 257 people per square mile. The county population is 4288. What is the area of this county?
ladessa [460]

Answer:

The area of the country is 17 square miles

Step-by-step explanation:

To calculate the population density of the country. We employ the use of a mathematical formula. This can easily be obtained from the units of the density

The population density = Population of the country/area of the country

Since we are to calculate the area of the country, the equation becomes

Area of country = Population of country/population density of country

Area of country = 4288/257

Area of country = 16.68 square mile

To the nearest square mile, the Area of the country = 17 square mile
