14. Let R^2 have inner product defined by ((x1,x2), (y,, y2)) 4x1y1 +9x2y2 A. Determine the norm of (-1,2) in this space B. Dete

Vitek1552 [10]

The norm of a vector $\vec x$ is equal to the square root of the inner product of $\vec x$ with itself.

a. $\|(-1,2)\|=\sqrt{\langle(-1,2),(-1,2)\rangle}=\sqrt{4(-1)^2+9(2)^2}=\sqrt{40}=2\sqrt{10}$

b. $\|(3,2)\|=\sqrt{\langle(3,2),(3,2)\rangle}=\sqrt{4(3)^2+9(2)^2}=\sqrt{72}=6\sqrt2$

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
