The 40th parallel of north latitude runs across the United States through Philadelphia, Indianapolis, and Denver. at this latitu

de earths radius is about 3030 miles. The earth rotates with an angular velocity of pi/12 radians per hour toward the east.
If a jet flies due west with the same angular velocity relative to the ground at the equinox the sun as viewed from the jet will stop in the sky. how fast in miles per hour with the jet have to travel west at the 40th parallel for this to happen?

Answer: 793 mi/h

Step-by-step explanation:

We have the following data:

R_{E}=3030 mi is Earth radius at the 40th parallel of north latitude

\omega_{E}=\frac{\pi}{12} rad/h is the Earth's angular velocity (toward the east)

\omega_{J}=\frac{\pi}{12} rad/h is the Jet's angular velocity (toward due west)

And we need to find the Jet's speed V_{J}, which is calculated by:

V_{J}=\omega_{J}R_{E}

V_{J}=(\frac{\pi}{12} rad/h)(3030 mi)

V_{J}=793.25 mi/h

Solutions 

 V=3.14r^2 * 20 

Radius = 75 

3.14 * 75^2 * 20 

3.14 * 5625 * 20 
 
17662.5 * 20

FIND THE SLOPE OF THE LINE...<br><br> A) 1/2<br><br> B) 2<br><br> C) - 1/2<br><br> D) -2
Ainat [17]

Answer:

The slope would be C) -1/2

Step-by-step explanation:

To find it, we need to use the slope formula and two points on the line. The points we'll use are (0, -3) and (2, -4)

m(slope) = (y2 - y1)/(x2 - x1)

m = (-3 - -4)/(0 - 2)

m = 1/-2

m = -1/2

In Diagram 1, the value of x is what?
Bezzdna [24]

Answer:

x = 18.75

Step-by-step explanation:

The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel

3x-10 = 65-x

Add x to each side

3x-10+x = 65-x+x

4x-10 = 65

Add 10 to each side

4x-10+10 = 65+10

4x = 75

Divide each side by 4

4x/4 = 75/4

x = 18.75
