OMG LOL i cant believe ur doin the ear defenders homework too!!!! i am completly stuck too but i do no that the best material for the outside is a nard shiny plastic!! hope that helps lol!!!

sorry about that: when t=0, r't=5.7; t=2, r't=4; t=5, r't=2; t=7, r't=1.2; t=11, r't=.6; t=12, r't=.5

1. .015*65*12+65=76.7 million 2. 4*65=260 million

Thank you for the response. That was the answer that I initially calculated using percentage change; however, the answer is that it was lowered by 16 2/3%. The explanation is that it now takes $6 to buy what used to cost $5. Each dollar is worth 1/6 less.

I can't calculate the correct answer.

I figured it out. 120-100=20, which is the net difference. Divide net difference by the new cost of 120, which equals 16.67 less.

I figured it out. 40 acres = 1320' x 1320'; P=2L + 2W; P=2(1320)+ 2(1320); P=5,280', which is a mile. Run the wire 3x, and it equals 3 miles.

c)3! x 6! The three must remain together but can be in any permutation with the rest. It would be 5! ways if the three books had to be in a certain position.

FORMAT WRONG ABOVE.... Correct one is.. Find dy/dt when y = 2x^2 + 2x + 4 and dx/dt = 14 when x = 7.
