To solve this problem you must apply the proccedure shown below:
1. You have that:
- <span>It completes one orbit every 5 hours.
- The radius of earth is about 6,400 km.
- The satellite is positioned 4,700 km above the earth.
2. Then, you must use the following formula:
S=r</span><span>θ
r=6,400 km+4,700 km
r=11,100 km</span><span>
3. When you substitute the values, you obtain:
S=(11,100 km x 2</span>π)/5
S=13,949 km
The answer is:13,949 km
Answer:
r=9
Step-by-step explanation:
We can use the Pythagorean to solve, since this is a right triangle
The leg lengths are r and 12
The hypotenuse is (r+6)
a^2 + b^2 = c^2
r^2 + 12^2 = (r+6)^2
Foiling out the right hand side
(r+6)(r+6_ = r^2+6r+6r+36
r^2 +144 = r^2 +12r+36
Subtracting r^2 from each side
r^2-r^2 +144 = r^2-r^2 +12r+36
144 = 12r+36
Subtract 36 from each side
144-36 = 12r+36-36
108 = 12r
Divide each side by 12
108/12 = 12r/12
9=r
-2(3(3)-4)+6(2(3)-7) = -16.
