- In Exercises 15-17, find a mathematical model that represents the statement. (Determine the constant of proportionality.) A varies jointly as xandy.A=500whenx=15andy=8.arrow_forwardThe kinetic energy E of an object varies jointly with the object’s mass m and the square of the object’s velocity v . An object with a mass of 50 kilograms traveling at 16 meters per second has a kinetic energy of 6400 joules. What is the kinetic energy of an object with a mass of 70 kilograms traveling at 20 meters per second?arrow_forwardThe rate of change of an autocatalytic chemical reaction is kQxkx2 where Q is the amount of the original substance, x is the amount of substance formed, and k is a constant of proportionality. Factor the expression.arrow_forward
- The maximum weight M that can be supported by a beam is jointly proportional to its width w and the square of its height h and inversely proportional to its length L. a Write an equation that expresses this proportionality. b Determine the constant of proportionality if a beam 4 in. wide, 6 in. high, and 12 ft long can support a weight of 4800 lb. c If a 10-ft beam made of the same material is 3 in. wide and 10 in. high, what is the maximum weight it can support?arrow_forwardIn Exercises 15-17, find a mathematical model that represents the statement. (Determine the constant of proportionality.) vvaries directly as the square root of s.v=24whens=16.arrow_forwardThe terminal velocity of a skydiver is reached typically about 10-12 seconds into a dive. The square of the terminal velocity of a skydiver (v) is directly proportional to the skydiver's weight (w) and inversely proportional to the skydiver's ground-facing surface area (A). Write an equation that models this situation. Use k for the constant of proportionality. Suppose Christy weighs 60 kilograms and has an approximate downward-facing area of 0.18 square meters. Last week, Christy went skydiving and the terminal velocity was measured as 241 kilometers per hour. If another person goes skydiving under similar conditons and they weigh 82 kilograms with a ground-facing surface area of 0.33 square meters, what would be their terminal velocity? kilometers per hour {Give at least 3 decimal place accuracy}arrow_forward
- A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 15 people. The government responds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month? Express your answer as an integer.arrow_forwardThe total number t of items that a manufacturing company can produce is directly proportional to the number n of employees. (a) Write an equation that shows the proportionality relation. (Let k be the constant of proportionality.) What in practical terms does the constant of proportionality represent in this case?arrow_forwardYou would think that your blood alcohol content (BAC) would be directly proportional to how many beers you drink in an hour. Strangely enough, for both males and females of a specific weight, the BAC is directly proportional to the number (N − 1) of beers they drank during the last hour. (a) Write an equation of variation between BAC and the number of beers a man drank during the last hour. (Use k as the constant of variation.)BAC = k(N−1) (b) For a 150-lb average man, his BAC after 3 beers is 0.046. Find k. (Round your answer to three decimal places.)k = (c) What is his BAC after 5 beers? (Round your answer to three decimal places.)(d) How many beers can the man drink before going over the 0.08 BAC limit? (Round your answer to the nearest whole number.) __________ beersarrow_forward
- If a 1600 foot bridge weighing 2100 tons supports 1400 tons, find the constant of proportionality k. B=k√1/warrow_forwardIf you work 42 hours per week, then your weekly pay P, in dollars, is proportional to your hourly wage W, in dollars per hour. Express this proportionality relationship as a formula.arrow_forwardA 30-second commercial during Super Bowl XXXVII in 2003 cost advertisers 2.2 million. For the first Super Bowl in 1967, an advertiser could have purchased approximately 26.19 minutes of advertising time for the same amount of money. (a) Assuming that advertising cost is proportional to its length of time, find the cost of advertising, in dollars/second, during the 2003 Super Bowl. cost= dollars/second. (round to nearest cent and do not enter commas) (b) Assuming that advertising cost is proportional to its length of time, find the cost of advertising, in dollars/second, during the 1967 Super Bowl. cost = dollars/second. (round to nearest cent and do not enter commas) (c) How many times more expensive was Super Bowl advertising in 2003 than in 1967? times more expensive (round to nearest whole number)arrow_forward
