About 1.75 million people live in a circular region with a 15-mile diameter. Find the population density in people per square mi

pav-90 [236]

About 1.75 million people live in a circular region with a 15-mile diameter. Find the population density in people per square mile.

Solution: We are given that the population of a circular region = 1.75 million = $1,075,000$

Also we are given the circular region has a diameter = 15 mile

Which means the radius of region $\frac{15}{2}=7.5$ mile

Therefore, the area of the circular region $=\pi r^{2}$

$=3.14 \times 7.5^{2}$

$=176.625$

Now the population density per square mile is:

$\frac{1075000}{176.625}$

$6086.34 \approx6086$

Therefore, the population density per square mile is 6086

Convert the equation, x - 2y = 6, into slope-intercept form.

MArishka [77]

Answer:

$\boxed {y = -\frac{1}{2}x + 3}$

Step-by-step explanation:

Convert the equation from <u>Standard Form</u> to <u>Slope-Intercept Form</u>:

$Ax + By = C$ ⇒ $y = mx + b$

-The following equation:

$x - 2y = 6$

-Solve:

$x - 2y = 6$

$x - x - 2y = 6 - x$

$2y = -x + 6$

$\frac{2y}{2} = \frac{-x}{2} + \frac{6}{2}$

$\boxed {y = -\frac{1}{2}x + 3}$

So, the equation in Slope-Intercept Form is $y = -\frac{1}{2}x + 3$ .
