Solve the problem. Use the mathematical model for power gain, G = log
(Ро/Pi)10
, where Po is the output power in watts and P; is
the input power in watts. Determine the power gain G,
in decibels, for an amplifier with an output Po of 29
watts and an input P; of 1.4 watts. Round to five
decimal places if necessary.

Select one:
O a. 16.08526 dB
O b. 13.1627 dB
O c.
14.1627 dB
O d. 14.40909 dB

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
