(The cattle don't swim, so there doesn't need to be any fence on the river side.) The rancher has 5000 yards of fencing. What dimensions will maximize the pasturage available for the animals? 2. On stage, a light is being lowered at a rate of half a foot per second, 5 feet away from a 6 foot tall actor. How fast is that actor's shadow growing when the light is 10 feet off the ground? (Hint: Use similar triangles to set this up. The Pythagorean Theorem isn't going to be very helpful. Also, it will be easiest to work with if you separate the variablesput the separate variables on different sides of the equation.(Otherwise, you'll have to use implicit differentiation to take the derivative of the equation with both variables in it. On the other hand, clearing the denominator will derivative of the equation with both variables in it....
