State Troopers set up a speed trap on a highway. Because the worst speeders usually have radar detectors, they decide not to use radar. They identify two points that are a known distance apart and position an observer where she can see both points. The observer has a stop watch and a radio. She will identify cars that are speeding and radio the description and tag number of each speeding car to other State Troopers who are waiting just around a bend in the road. The Troopers know that different speedometers have different amounts of error. In order to avoid giving tickets to people who have small speedometer errors and focus on the worst speeders, they decide to allow cars to be a small amount over the speed limit without getting a ticket. A car travelling at the speed limit will take exactly 10 seconds to travel between the two points. The Troopers decide not to give a ticket to anyone who takes 9 seconds or longer to travel between the two points. What is the maximum percent error, to the nearest percent, in the time measurement that the Troopers are allowing in this situation

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?

The second largest public utility in the nation is the sole provider of electricity in 32 counties of southern florida. to meet the monthly demand for electricity in these counties, which is given by the inverse demand function p = 1,200 – 4q, the utility company has set up two electric generating facilities: q1 kilowatts are produced at facility 1, and q2 kilowatts are produced at facility 2 (so q = q1 + q2). the costs of producing electricity at each facility are given by c1(q1) = 8,000 + 6q12 and c2(q2) = 6,000 + 3q22, respectively. determine the profit-maximizing amounts of electricity to produce at the two facilities, the optimal price, and the utility company’s profit

Sasha has just gotten a new job in a nearby city. after comparison shopping, she found that renting a nice two-bedroom apartment would cost around $800 per month. her utilities would cost about $150 per month. sasha has enough money saved for a down payment, and she found that she can buy a three-bedroom house or condo with a mortgage payment of $1,000 per month, including taxes and homeowner's insurance. her utilities would cost about $200 per month. what is the advantage of buying the house over renting the apartment?
