Ms. Estevez won first prize, a trip to Hawaii.

The trim around a window has a total length of $\frac { r t } { w ^ { 3 } } \left( \frac { r t y } { w } + 2 t y - \frac { 8 } { w ^ { 2 } } \right)$ a. Simplify the expression. b. Identify the variables that cannot equal zero.

Using the vocabulary of this lesson, determine the etymological meaning of given of the following uninomial and binomial terms. Find the modern biological meaning of given of these terms in a medical dictionary.

Determine whether each statement makes sense or does not make sense, and explain your reasoning. Because I know how to clear an equation of fractions, I decided to clear the equation 0.5x+8.3=12.4 of decimals by multiplying both sides by 10.

What are the terms of each expression?

$$7x + 8y - 9z$$

Combine like terms.

$$-9 x-13 x+7$$

Two waveforms, $v_1(t)$ and $v_2(t)$, have identical amplitudes and oscillate at the same frequency, but $v_2(t)$ lags $v_1(t)$ by a phase angle of $60^{\circ}$. If

$$v_1(t)=4 \cos \left(2 \pi \times 10^3 t+30^{\circ}\right) \mathrm{V},$$

write the expression appropriate for $v_2(t)$ and plot both waveforms over the time span from $-1 \mathrm{~ms}$ to $+1 \mathrm{~ms}$.

Ms. White asked the 25 sixth graders in her class, "How many pets do typical oth graders in our class have?" Ms. White summarized the responses in the table.

$$\begin{array}{|c|c|}\hline \text { Number of } & {\text { Number of }} \\ \text { Students } & {\text { Pets }} \\ \hline 8 & {0} \\ \hline 10 & {1} \\ \hline 4 & {2} \\ \hline 2 & {3} \\ \hline 1 & {38} \\ \hline\end{array}$$

About how many pets does each sixth grader in Ms. White's class own? How did you make your decision?

Consider the function f(x) = 1/2 (ax)² - ax, a ≠ 0. (a) Determine the changes (if any) in the intercepts, extrema, and concavity of the graph of f when a is varied. (b) In the same viewing window, use a graphing utility to graph the function for four different values of a.

Can you disable editing of a text area?

Find the frequency of a repeating waveform whose period is a. 1 s. b. $\frac{1}{16}$ s. c. 40 ms. d. 25 $\mu$ s.

Did Ms. Rubio (advice, advise) you to take cheerleading?

A brass rod $1.020 \mathrm{~m}$ long expands $3.0 \mathrm{~mm}$ when it is heated. Calculate the temperature change.

Graph the function in the given viewing window. Then determine the domain and the range.

$f(x)=x^4-2 x^2-7, \quad[-4,4,-9,9]$
