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.

Answer:

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×\pi×3960×cos 0°

C=2×\pi×3960×1

C=7380\pi

Taking L=45° and r=3960 then;

C= 2×\pi×3960×cos 45°

C=5600.28\pi

Taking L=60° and r=3960 then;

C=2×\pi×3960×cos 60°

C=3960\pi

Taking L=90° and r=3960 then;

C=2×\pi×3960×cos 90°

C=2×\pi×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

justin has 7.50 more than eva and emma has 12 less than justin. together, they have a total of 63.00. how much does each person
lina2011 [118]
1st statement
Justin has 7.5 more than Eva        7.5+E
Eva = E
2nd statement
Emma has 12 less than Justin         J - 12
when J= Justin = 7.5 + E
last statement
Eva+Justin+Emma = 63
E + (7.5+E) + (7.5+E-12) =63
ADD UP
3E + 15 - 12 = 63
3E + 3 = 63
3E=63 - 3
3E=60
E=20 EMMA receives 20
J=7.5+20
J=27.5  JUSTIN receives 27.5
M=J-12
M=27.5-12
M=15.5  EMMA receives 15.5
