54. log(20x) - log4 = 2​

Mathematics
1 answer:
Luba_88 [7]3 years ago
4 0

Answer:

x=e^2/5

Step-by-step explanation:

log(20 x) - log(4) = 2

Add log(4) to both sides:

log(20 x) = 2 + log(4)

Cancel logarithms by taking exp of both sides:

20 x = 4 e^2

Divide both sides by 20:

And we get Answer:

x = e^2/5

PLEASE SOVEL THIS I WILL GIVE OUT 20 POINT
Anettt [7]

9514 1404 393

Answer:

  21.25 seconds

Step-by-step explanation:

In miles per second, the speed of the jet is ...

  (720 mi/h)/(3600 s/h) = 1/5 mi/s

The speed of the sound is the same:

  (1 mi)/(5 s) = 1/5 mi/s

Then the rate of closure between the airplane and the sound is ...

  (1/5 mi/s) +(1/5 mi/s) = 2/5 mi/s

To find the time required to close a gap of 8 1/2 miles, we can use the relation ...

  time = distance/speed

  time = (8.5 mi)/(0.4 mi/s) = 21.25 s

The pilot will hear the thunder 21.25 seconds after the flash.
