#4. (25 pts) A centrifugal pump has $r_1 = 10$ cm, $r_2 = 18$ cm, $b_1 = 15$ cm, $b_2 = 10$ cm, $\beta_1 = 25^\circ$, and $\beta_2 = 40^\circ$ and rotates at 1,160 r/min. If the fluid is water at $20^\circ$C and the flow enters the blades radially, estimate the theoretical (a) flow rate in L/min, (b) horsepower, and (c) head in m. For relevant equations, please see page 8. Hint: $\rho_{water} = 998$ kg/$m^3$

Develop a strategy to reduce or eliminate misbehavior using behaviorist principles. Describe the specific behavior you will reinforce and the reinforcer you will use. If possible, you should also specify when you will use continuous and intermittent reinforcement. Roy cheats on tests as often as he can

Evaluate the following limit or explain why it does not exist.\\ $\lim_{x \to 0} (20x + \cos x)^{\frac{1}{x}}$ Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice.\ A. $L = \lim_{x \to 0} \frac{1}{x} \ln(20x + \cos x)$ is finite and therefore $\lim_{x \to 0} (20x + \cos x)^{\frac{1}{x}}$ can be written as the expression (Type an expression using L as the variable.)\ This implies that $\lim_{x \to 0} (20x + \cos x)^{\frac{1}{x}} = $ (Type an exact answer in simplified form.)\ B. The limit does not exist because it has the indeterminate form $\infty^0$ which cannot be written in the form $\frac{0}{0}$ or $\frac{\infty}{\infty}$ so that l'Hôpital's rule can be applied.\ C. The limit does not exist because it has the indeterminate form $0^0$ which cannot be written in the form $\frac{0}{0}$ or $\frac{\infty}{\infty}$ so that l'Hôpital's rule can be applied.\ D. The limit does not exist because it has the indeterminate form $1^\infty$ which cannot be written in the form $\frac{0}{0}$ or $\frac{\infty}{\infty}$ so that l'Hôpital's rule can be applied.
