It would be log3 14/log3 4
Hope this helps. (:
Answer:
slope: 2/3
y intercept: -1
Step-by-step explanation:
slope: rise/run
-m-4=-13
-m=-13+4=-9
m=9

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:
(C)
Step-by-step explanation:
Given the distance, d(t) of a particle moving in a straight line at any time t is:

To find an expression for the instantaneous velocity v(t) of the particle at any given point in time, we take the derivative of d(t).

The correct option is C.
