ASK YOUR TEACHER Unemployment and inflation are inversely related, with one rising as the other falls, and an equation giving the relation is called a Phillips curve after the economist A. W. Phillips (191471975). Phillips used data from 1861 to 1957 to establish that in the United Kingdom the unemployment rate x and the wage inflation rate y were related by y : 9 538261-394 , 0.900 where x and y are both percents t Use this relation to estimate the inflation rate when the unemployment rate was 2 percent and 4 percent (Round your answers to two decimal places.)

Police or insurance investigators often want to estimate the speed of a car from the skidmarks it left while stopping. A study found that for standard tires on dry asphalt, the speed (in mph) is given approximately by y = 9.4x0.37, where x is the length of the skidmarks in feet. (This formula takes into account the deceleration that occurs even before the car begins to skid.) Estimate the speed of a car if it left skidmarks of the following length. (Round your answer to the nearest mile per hour.) + 230 feet mph Show My Work (Optional) ? 13. [0/3.15 Points] DETAILS PREVIOUS ANSWERS BERRAPCALCBR7 1.3.009.
