How is economic growth measured? Why is economic growth important? Why could the difference between a $2.5$ percent and a $3$ percent annual growth rate be of great significance over several decades?

Use Stokes’ Theorem to evaluate

$$\mathbf{F}(x,y,z)=(x+y^2-2)\mathbf{i}+2xy\mathbf{j}+(x^2+yz^2)\mathbf{k};$$

S is the part of the paraboloid z = 4 - x squared - y squared above the xy-plane with an outward normal

Identify the number as real, complex, pure imaginary, or nonreal complex. (More than one of these descriptions will apply.)

$$\pi$$

Provide structures for the semicarbazone and the $2,4$-dinitrophenylhydrazone of citral.

You have a 1-m-wide, 2-m-long 14-kg wooden board. If you place a 5.0-kg pot of soup in one corner of the board, where is the center of mass of the board-pot system?

What terminates a muscle contraction? ____________________________

The $1$-m-diameter tank in Fig. P6.145 is initially filled with gasoline at $20^{\circ} \mathrm{C}$. There is a $2$-$\mathrm{cm}$-diameter orifice in the bottom. If the orifice is suddenly opened, compute the time for the fluid level $h(t)$ to drop from $2.0$ to $1.6 \mathrm{~m}$.

Infection that weakens the heart muscle is called _______.

Determine whether each statement is true or false. If it is false, tell why.

Every pure imaginary number is a complex number.

Identify each number as real, complex, pure imaginary, or nonreal complex. (More than one of these descriptions will apply.) -4

Consider the data set 7, 9, 14, 15, 22. The standard error of the sample mean is: A. 2.53 B. 2.56 C. 2.59 D. 2.62 E. 2.65

You are given the sample mean and the sample standard deviation. Assume the population is normally distributed and use the t-distribution to find the margin of error anti construct a 95% confidence interval for the population mean. Interpret the results. In a random sample of 12 mobile devices the mean repair cost was $90.42 and the standard deviation was$33.61.

Identify which of the following chemical formulas represent pure elements:

$$H_2, H_2O, He, Na, NaCl, Au, U.$$
