Let J be the region in the first quadrant bounded by the x-axis, the curve y = √x, and the line x = 9. 1. Set up an integral expression that finds the volume of the solid formed by revolving region J bounded about x-axis.
2. Set up an integral expression that finds the volume of the solid formed by revolving region J bounded about the line x = 9.

Elena and her husband marc both drive to work. elena's car has a current mileage (total distance driven) of 15,000 and she drives 23,000 miles more each year. marc's car has a current mileage of 46,000 and he drives 9,000 miles more each year. will the mileages for the two cars ever be equal? explain.

Problem situation: caren is making rice and beans. she can spend no more than $10 on ingredients. she buys one bag of rice for $4.99. beans cost $0.74 per pound. how many pounds of beans, x, can she buy? inequality that represents this situation: 10≥4.99+0.74x drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution.

Yvaries directly as x. y =90 when x=6. find y when x=13
