Question

When p = 12, t = 2, and s = 1/6, r = 18. If r varies directly with p and inversely with the product of s and t, what is the constant of variation?

Answer 1

What is the maximum value of P = 24x + 30y, given the constraints on x and y listed below?

Answer 2

The mass of an object varies directly with the potential energy of the object and inversely with the height of the object off the ground. A 25-kg object has 980 joules of potential energy when it is 4 meters off the ground. Another object has 150 joules of potential energy at 3 meters off the ground. What is the mass of the second object?
