Answer:
Explanation:
1) You can draw a right triangle where the distance of 17,000 miles from the horizon of Earth is leg, perpendicularto the radius of the Earth, and such radius is the other leg, 4,000 miles.
2) By the construction of the right triangle, the hypotenuse is the sum of the height of the satelite (unknown, x) plus the radius of the Earth (4,000) = x + 4,000.
3) Now, you can use Pythagora's theorem:
- (x+4,000)² = 4,000² + 17,000²
- (x + 4,000)² = 305,000,000
- (x + 4,000) = 17,464 (take only the positive root)
- x = 17,464 - 4000 = 13,464
Remember to include the units: miles.
Answer: 13,464 miles.

This an Arithmetic Progression question: (odd number: 1,3,5,7,...)
1st term a₁ = 1
the common difference is d=2
a term of rank n in a AP = a₁ + (n-1)d, where n = rank of the term.
Now let's apply the formula
a₈₇ = a₁ + (87-1).2
a₈₇ = 173
Answer:
Top box: Endpoint
Bottom box: Ray
Step-by-step explanation:
Assuming that the top box is supposed to be for the point shared by both rays, then it is a endpoint of the rays, as the lines do not continue past the point on the opposite side.
The bottom box will then be a ray, as no point is shown, and a arrow is used at the "end" of the line to signify that it will continue on <em>forever</em>.
