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.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
