Answer:
c
Step-by-step explanation:
The time taken for radio signal to the earth's surface we shall proceed as follows;
time=(distance)/(speed)
Distance=7.5×10^6 meters
speed=3×10^8 meters/second
therefore:
Time=(7.5×10^6)/(3×10^8)=0.025 seconds
We conclude that it will take the signal 0.025 seconds to reach the surface of the earth.

Answer:
D. 5x - 1
Step-by-step explanation:
(f+g)(x) ➡ f(x) + g(x)

Answer:
20
Step-by-step explanation:
This triangle can be solved using the Pythagorean theorem. 16^2+12^2=x^2. 16^2+12^2=400. If we set 400 equal to x^2, x=20.
