The length of the arc between L A and Miami = 2700 miles
length of arc = r*c where c is in radians
2700 = 3960 * c
c = 2700/3960 = 0.68182 radians+
The tangents from the satellite to the 2 points on the earth make a 90 degree angle with the radii of the earth, so we have 2 right angled triangles with one angle = 1/2 * 0.68182 = 0.34091 radians and the hypotenuse is the distance from center of the earth to the satellite.
if x is the distance of the satellite from the surface of the earth we have the equation
cos 0.34091 = 3960 /( x + 3960)
cos 0.34091(x + 3960) = 3960
x = (3960 - cos0.3409* 3960) / cos0.34091
= 241.8 miles Answer
Answer:
1. -4
2. 8/ 5 - 1. 6
Step-by-step explanation:
1 . 3 × -4
= (-12)
2. 2/5 × 4
= 8 / 5
= 1.6
Hope this answer helps you :)

Answer:
40.2
Step-by-step explanation:
Diameter = 16, Radius = 16/2 = 8
Central angle = 2π/5 radians = 72°
Sector area,
8²π×(72/360)
= 64π/5
= 40.2 (rounded to the nearest tenth)
