For the first problem, we use the trigonometric function cosine. The equation would be:
cos (1/2)θ = 3960 / (3960 + 90)
Solving for θ
θ = 24.20°
Solving for the distance the satellite can see:
s = rθ
s = 3960 (24.20) π/180
s = 1672.79 mi
The satellite can see1672.79 mi of distance.
For the second problem, we approach the reverse manner as the first problem.
Solving for the angle,
θ = s/r
θ = 3000 / 3960
θ = 0.7576 (180/π) = 43.41°
Solving for h:
cos 1/2 (43.41) = 3960 / (3960 + h)
h = 302.19 mi
The satellite must be 302.19 mi above the Earth.
Answer:
(14 + 4)c, or 18c
Step-by-step explanation:
The answer is B. an = 13 + 14(n-1)
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
Subtract 8 from both sides
x + 8 (-8) = -2 (-8)
x = -2 - 8
Combine
x = -10
-10 is your answer for x
hope this helps
