The rate of change in revenue for under armour from 2004 through 2009 can be modeled by dr dt = 13.897t + 284.653 t where r is the revenue (in millions of dollars) and t is the time (in years), with t = 4 corresponding to 2004. in 2008, the revenue for under armour was $725.2 million.† (a) find a model for the revenue of under armour. (round your constant term to two decimal places.) r(t) = 6.9485t2+284.653ln(t)−311.42 (b) find under armour's revenue in 2006. (round your answer to two decimal places.)

Steele bicycle manufacturing company currently produces the handlebars used in manufacturing its bicycles, which are high-quality racing bikes with limited sales. steele produces and sells only 10,000 bikes each year. due to the low volume of activity, steele is unable to obtain the economies of scale that larger producers achieve. for example, steele could buy the handlebars for $31 each: they cost $34 each to make. the following is a detailed breakdown of current production costs: after seeing these figures, steele's president remarked that it would be foolish for the company to continue to produce the handlebars at $34 each when it can buy them for $31 each. calculate the total relevant cost. do you agree with the president's conclusion?

Acompany is developing a new high­performance wax for cross country ski racing. in order to justify the price marketingwants, the wax needs to be very fast. specifically, the mean time to finish their standard test course should be less thanseconds for a former olympic champion. to test it, the champion will ski the course 8 times. the champion's times(selected at random) are 59.9 61.9 48.8 52.2 46.6 45.3 50.6 and 41.1 seconds to complete the test course. complete parts a and b below. a) should they market the wax? assume the assumptions and conditions for appropriate hypothesis testing are metfor the sample. assume=0.05. what are the null and alternative hypotheses? choose the correct answer below. b) suppose they decide not to market the wax after the test, but it turns out that the wax really does lower the champion'saverage time to less thanseconds. what kind of error have they made? explain the impact to the company of such anerror.
