Atruck has a minimum speed of 14 mph in high gear. when traveling x mph, the truck burns diesel fuel at the rate of 0.0065413(1024x+x)gal/mile assuming that the truck can not be driven over 56 mph and that diesel fuel costs $1.69 a gallon, find the following. (a) the steady speed that will minimize the cost of the fuel for a 580 mile trip. x= 31366.4 (b) the steady speed that will minimize the total cost of a 580 mile trip if the driver is paid $18 an hour. x= (c) the steady speed that will minimize the total cost of a 360 mile trip if the driver is paid $28 an hour.

Two conductors, a and b, are each in the shape of a tetrahedron. but of different sizes. they are charged in the following manner: 1. tetrahedron a is charged from an electrostatic generator to charge q. 2. tetrahedron a is briefly touched to tetrahedron b. 3. steps 1 and 2 are repeated until the charge on tetrahedron b reaches a maximum value. if the charge on tetrahedron b was q/4 after the first time it touched tetrahedron a. what is the final charge qbmax on tetrahedron b?
