A transmission line has an input voltage of 0.4 volts and a decibel voltage gain of 18.6 decibels. Find the output voltage.

  3.4 volts

Step-by-step explanation:

For voltage gain, the number of decibels is 20 times the base-10 logarithm of the actual gain. Then the ratio of output to input is ...

  20·log(Vout/Vin) = 18.6

  Vout/Vin = 10^(18.6/20) ≈ 8.5114

So, the output voltage is ...

  Vout = 8.5114·Vin = 8.5114·0.4 volts ≈ 3.4046 volts

The output voltage is about 3.4 volts.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
