Answer:
The approximate distance is 15416 miles....
Step-by-step explanation:
We have given:
A satellite is 19,000 miles from the horizon of earth.
The radius is 4,000 miles.
Lets say that BC =x
AO = OB = 4,000 miles
AC = 19,000 miles
The tangent from the external point forms right angle with the radius of the circle.
So in ΔABC
(OC)² = (AC)²+(OA)²
where OC = x+4000
AC = 19,000
OA = 4000
Therefore,
(x+4000)² = (19,000)² +(4,000)²
Take square root at both sides:
√(x+4000)² = √(19,000)² +(4,000)²
x+4000 =√361000000+16000000
x+4000 = √377000000
x+4000 = 19416.48
x= 19416.48 - 4000
x = 15416.48
Therefore the approximate distance is 15416 miles....
Answer:
The answer to your question is: x = - 102
Step-by-step explanation:



-x = 17 x 6
-x = 102
x = -102
The line which represents the equation x = 5 is a vertical line that passes through any point hax x-coordinate of 5
Then the perpendicular line to this line must be a horizontal line
The equation of any horizontal line is y = b, where
b is the y-coordinate of any point that lies on the line
Since the line passes through the point (-2, 2), then
b = 2
Then the equation of the line is
y = 2
