Solve.The inductance L in micro henrys of a coil constructed by a ham radio operator is equal to the product of the square of the coil's radius and the square of the number of turns of wire in the coil divided by the sum of 8 times the coil's radius and 10 times the coil's length. Set up this equation and solve for L if the radius is 2 inches, the number of turns of wire is 150 and the coil's length is 7 inches. Round to the nearest hundredth.

Solve the problem.Brand A soup contains 854 milligrams of sodium. It is recommended that a person requiring 2000 calories daily consume 2500 mg of sodium or less per day. Graph the function, f, that computes the number of mg of sodium in x cans of soup together with y1 = 2500, y2 = 5000, y3 = 7500 in [0, 10, 1] by [0, 8000, 1000]. Use the intersection-of-graphs method to find how many cans of soup contain 1, 2, and 3 daily allowances of sodium.
