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
[Note that you don't have to evaluate k to solve the problem]
That means that
So, you want 
such that
Answer:
Option A. k = 4.5, 54 cm
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
In this problem the constant of proportionality is equal to the scale factor
step 1
Find the scale factor
Let
k -----> the constant of proportionality
-----> ratio of the corresponding sides
step 2
Find the value of x
therefore
k = 4.5, 54 cm
The variable y in the 2nd equation has a coefficient of 1...so there will be fewer steps to the solution
