Find the variation constant and an equation of variation for the given situation. y varies directly as x, and y = 0.1 when x = 0.2 y varies inversely as x, and y = 12 when x = 5 y varies inversely as x, and y = 0.1 when x = 0.5 y varies directly as x, and y = 3 when x = 33 . . 1 y varies Inversely as x, and y = 3 when x = 35 f. y varies directly as x, and y = 0.9 when x = 0.4 The amount of sales tax paid on a product is directly proportional to the purchase price. In Iowa, the sales tax on a Nook Glowlight that sells for $119 is $7.14. What is the sales tax on an e-book that sells for $21? The weight W that a horizontal beam can support varies inversely as the length L of the beam. Suppose that an 8m beam can support 1200 kg. How many kilograms can a 14-m beam support? The number of representatives N that each state has varies directly as the number of people P living in the state. If California, with 38,333,000 residents, has 53 representatives, how many representatives does Texas, with a population of 26,448,000, have? The time t required to empty a tank varies inversely as the rate r of pumping. If a pump can empty a tank in 45 min at the rate of 600 kL/min, how long will it take the pump to empty the same tank at the rate of 1000 kL/min? The relative aperture, or f-stop, of a 23.5-mm diameter lens is directly proportional to the focal length F of the lens. If a 150-mm focal length has an f-stop of 6.3, find the f-stop of a 23.5-mm diameter lens with a focal length of 80 mm. '5 70"F Mostly cloudy + Ann-- 7:48 PM 'lO/4/2021 El
