For each expression, give the exact value. $\tan 60^{\circ}$

Describe worst-case input for the text search algorithm.

The natural frequencies of a wind instrument change when it is brought inside from the cold outdoors. Why do the frequencies change, and is the change an increase or a decrease? Justify your answers.

Determine whether each statement is always, sometimes, or never true. The diagonals of a parallelogram are congruent.

Teams A and B meet in a play-off. The first team that wins two games wins the play-off. Let X be the number of games won by team A. For any given game the probability that team A wins is 0.6. Find the probability distribution of X.

Magnesia (MgO) is used for fire brick, crucibles, and furnace linings because of its high melting point. It is produced by decomposing magnesite (MgCO3) at around $1200 ^ { \circ } \mathrm { C }.$

Use $\Delta \mathrm { H } ^ { \circ }$ and $S ^ { \circ }$ values to find $\Delta G ^ { \circ }$ at 298 K.

Assume that the matrices are partitioned conformably for block multiplication. Find formulas for X, Y, and Z in terms of A, B, and C, and justify your calculations. In some cases, you may need to make assumptions about the size of a matrix in order to produce a formula.

$$\left[ \begin{array}{ll}{X} & {0} \\ {Y} & {Z}\end{array}\right] \left[ \begin{array}{ll}{A} & {0} \\ {B} & {C}\end{array}\right]=\left[ \begin{array}{ll}{I} & {0} \\ {0} & {I}\end{array}\right]$$

Recall that the surface area of a person's body may be measured by the empirical formula $S(W, H)=0.0072 W^{0.425} H^{0.725}$ where W (kg) and H (cm) are the person's weight and height, respectively. Currently, a child weighs 34 kg and is 120 cm tall. a. Compute the partial derivatives $S_W (34, 120)$ and $S_H (34, 120),$ and interpret each as a rate of change. b. Estimate the change in surface area that results if the child's height stays constant but her weight increases by 1 kilogram.

Find the partial fractions decomposition and an antiderivative. If you have a CAS available, use it to check your answer. $\frac{x^{3}-4}{x^{3}+2 x^{2}+2 x}$
