Ernie and Mike painted a fence together in $a$ hours. It would have taken Ernie $b$ hours to paint the fence by himself. What fraction of the fence did Ernie paint? What fraction of the fence did Mike paint?

The base of a circular fence with radius 10 m is given by x = 10 cos t, y = 10 sin t. The height of the fence at position (x, y) is given by the function

$$h(x, y) = 4 + 0.01(x^2-y^2),$$

so the height varies from 3 m to 5 m. Suppose that 1 L of paint covers 100 m^2. Sketch the fence and determine how much paint you will need if you paint both sides of the fence.

What is $\mathrm { NAD } ^ { + } ?$ Why is it important?

The base of a circular fence with radius 10 m is given by $x = 10\cos t, y = 10\sin t$. The height of the fence at position $(x, y)$ is given by the function $h(x, y) = 4 + 0.01(x^2 - y^2),$ so the height varies from 3 m to 5 m. Suppose that 1 L of paint covers 100 m$^2$. Sketch the fence and determine how much paint you will need if you paint both sides of the fence.

What is $2^{2^{2006}}(\bmod 3) ?$

Paul wanted to fence in a square pasture for Babe, his blue ox. Each side needed to be 25 miles long. How many miles of fence did Paul need for the pasture?
