The distance from around the earth along a given latitude can be found using the formula c=2∏r cos l , where r is the radius of the earth and l is the latitude. the radius of earth is approximately 3960 miles. describe the distances along the latitudes as you go from 0° at the equator to 90° at the poles.

The distance reduces to 0 as you go from 0° to 90°

Step-by-step explanation:

The question requires you to find the distance using different values of L and check the trend of the values.

Given C=2×pi×r×cos L where L is the latitude  in ° and r is the radius in miles then;

Taking r=3960 and L=0° ,

C=2××3960×cos 0°

C=2××3960×1

C=7380

Taking L=45° and r=3960 then;

C= 2××3960×cos 45°

C=5600.28

Taking L=60° and r=3960 then;

C=2××3960×cos 60°

C=3960

Taking L=90° and r=3960 then;

C=2××3960×cos 90°

C=2××3960×0

C=0

Conclusion

The values of the distance from around the Earth along a given latitude decreases with increase in the value of L when r is constant

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
