Because the variable x is missing, the surface is a with rulings parallel to the 'I . The generating curve is z = y2. The domain is the entire xy-plane and the range is z 2 l:. Sketch the surface given by the function. RAC In 2016, an investment of $2000 was made in a bond earning 8% compounded annually. Assume that the buyer pays tax at rate R and the annual rate of inflation is I. In the year 2026, the value V of the investment in constant 2016 dollars is V(I, R) = 2000 1 + 0.08(1 - R) 10 1 + 1 Use this function of two variables to complete the table.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTH According to the Ideal Gas Law, PV = KT, where P is pressure, V is volume, T is temperature (in kelvins), and k is a constant of proportionality. A tank contains 400 cubic inches of nitrogen at a pressure of 130 pounds per square inch and a temperature of 300 K. (a) Determine k. K = (b) Write P as a function of V and T and describe the level curves. P = Setting P = c, the level curves are of the form V =
