Step-by-step explanation:
Step-by-step explanation:
It's a growth exponential graph.
Domain = All real numbers
Range= y>-5
y-int= -5
x=0 , so 3^0-5=-5
Asymptote: -5
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.
