Three Children are trying to balance on a seesaw, which consists of a fulcrum rock, acting as a pivot at the center, and avery light board 3.6 m long. Two playmates are already on either end. Boy A has a mass of 50kg, and girl B a mass of 35 kg. Where should girl C, whose mass is 25 kg, placed herself so as to balance the seesaw.

You can still ask an expert for help

Water stands at a depth H in a large, open tank whose sidewalls are vertical. A hole is made in one of the walls at a depth h below the water surface.

a) at what distance R from the foot of the wall does the emerging stream strike the floor?

b) How far above the bottom of the tank could a second hole be cut so that the stream emerging from it could have the same range as for the first hole?

Consider the surface given by the function $f(x,y)=\frac{4}{\sqrt{{x}^{2}+{y}^{2}-9}}$. What is the range of $f$? Determine any $y$-intercept(s) of $f$.

For range, I realize that $\sqrt{{x}^{2}+{y}^{2}-9}$ can be any number, so long as ${x}^{2}+{y}^{2}-9$ is positive or equal to zero. However, when looking at $f$, we know that the denominator cannot equal zero, which means that $\sqrt{{x}^{2}+{y}^{2}-9}$ can be any number greater than $0$. Would this mean that the range of $f$ is $(0,\mathrm{\infty})$?

For the $y$-intercept, I know that both $x$ and $z$ need to equal zero. Would this mean that there are no $y$-intercepts because $0$ is not in the range of $f$?
