2. Suppose there are 6 million people in New York City that walk an average of 2.5 miles per day. If we add up all the miles wal

ked by these 6 million how many times around the Earth would these walkers have gone? Assume the distance around the Earth is 2.5 * 10 ^ 4 miles. Write your result in scientific notation.

Answer:

  • 600 times

Step-by-step explanation:

<h3>Given</h3>

<u>Number of people:</u>

  • 6 million = 6*10^6

<u>Distance to walk:</u>

  • 2.5 miles per day per person

<u>Distance around the Earth</u>

  • 2.5*10^4
<h3>Solution</h3>

<u>Total distance walked:</u>

  • 6*10^6*2.5 = 15*10^6

<u>The ratio of total distance to the distance around the Earth:</u>

  • 15*10^6 / 2.5*10^4 = 6*10^2 = 600 times

Number of people:

6 million = 6 × 10^{6}

Distance to walk:

2.5 miles every day per person

Distance around the Earth

2.5 ×10^{4}

Total distance walked:

6 × 10^{6} × 2.5 = 15 × 10^{6}

The ratio of total distance to the distance around the Earth:

15 × 10^{6} / 2.5 × 10^{4} = 6 × 10^{2} = 600

Try to sketch by hand the curve of intersection of the parabolic cylinder y = x2 and the top half of the ellipsoid x2 + 7y2 + 7z
vovikov84 [41]

Plug y=x^2 into the equation of the ellipsoid:

x^2+7(x^2)^2+7z^2=49

Complete the square:

7x^4+x^2=7\left(x^4+\dfrac{x^2}7+\dfrac1{14^2}-\dfrac1{14^2}\right)=7\left(x^2+\dfrac1{14}\right)^2+\dfrac1{28}

Then the intersection is such that

7\left(x^2+\dfrac1{14}\right)^2+7z^2=\dfrac{1371}{28}

\left(x^2+\dfrac1{14}\right)^2+z^2=\dfrac{1371}{196}

which resembles the equation of a circle, and suggests a parameterization is polar-like coordinates. Let

x(t)^2+\dfrac1{14}=\sqrt{\dfrac{1371}{196}}\cos t\implies x(t)=\pm\sqrt{\sqrt{\dfrac{1371}{196}}\cos t-\dfrac1{14}}

y(t)=x(t)^2=\sqrt{\dfrac{1371}{196}}\cos t-\dfrac1{14}

z=\sqrt{\dfrac{1371}{196}}\sin t

(Attached is a plot of the two surfaces and the intersection; red for the positive root x(t), blue for the negative)
