Solve.In physics, if an object is in motion it has kinetic energy. The formula 
is used to calculate the kinetic energy, E, of an object with a mass m and velocity v. If the mass is measured in kilograms and the velocity is in meters per second, then the kinetic energy will be in units called joules (J). Suppose an object with a mass of 40 kilograms has 2,000 joules of kinetic energy. Find its velocity. Round to the nearest tenth if necessary.
A. 25 m/sec B. 10 m/sec C. 5 m/sec D. 100 m/sec

Solve the problem.Daniel decides to feed his cat a combination of two foods: Max Cat and Mighty Cat. He wants his cat to receive four nutritional factors each month. The amounts of these factors (a, b, c, and d) contained in one bag of each food are shown in the chart, together with the total amounts needed. 
The costs per bag are $43 for Max Cat and $37 for Mighty Cat. How many bags of each food should be blended to meet the nutritional requirements at the lowest cost? Set this up as a linear programming problem in the following form:Minimize cTx subject to Ax ? b and x ? 0. Do not find the solution.
