In Exercise given below, sketch the region R whose area is given by the double integral. Then change the order of integration and show that both orders yield the same area.

$$\int_{-2}^2 \int_0^{4-y^2} d x d y$$

Circle the word in the list above that means "a cell that is undifferentiated and can turn into different types of cells."

Look again at the earlier explore activity. Start with the original figure. Create a new sequence of transformations that will yield figure $E$, the final image. Your transformations do not need to produce the images in the same order in which they originally appeared.

The total revenue R earned (in thousands of dollars) from manufacturing handheld video games is given by R(p) = -25p^2 + 1200p Find the unit price that will yield a maximum revenue. What is the maximum revenue? Explain your results.

Why is it unlikely that organic molecules would accumulate in the oceans today?

An electric field points away from a charge. What is the sign of the charge?

Write a nuclear equation for the indicated decay of each nuclide. a. U-234 (alpha ), b. Th-230 (alpha), c. Pb-214 (beta), d. N-13 (positron emission), e. Cr-51 (electron capture)

Thomas Corporation’s adjusted trial balance contained the following liability accounts at December 31, 2017: Bonds Payable (due in 3 years) $100,000, Accounts Payable$72,000, Notes Payable (due in 90 days) $22,500, Salaries and Wages Payable$4,000, and Income Taxes Payable $7,000. Prepare the current liabilities section of the balance sheet.

What types of evidence enable scientists to make inferences about the sizes, temperatures and distances of stars?

In $\left[\mathrm{Fe}(\mathrm{CN})_6\right]^{3-}$, a realistic charge distribution results in each ligand carrying a charge of $-\frac{2}{3}$. In this model, what charge does the Fe centre carry and why is this charge consistent with the electroneutrality principle?

A delivery company has a fleet of vans. The annual operating cost $C$ per van is

$$C=0.32 m+2500$$

where $m$ is the number of miles traveled by a van in a year. What number of miles will yield an annual operating cost of $\$ 10,000$?

What term matches the definition?

Estimate the net force on a 2.0-C charge at the origin of an $x y$-coordinate system if there is a $+5.0$-C charge at $(3 \mathrm{~m}, 0)$ and a $-3.0$-C charge at $(0,4 \mathrm{~m})$.

Butane $\left(\mathrm{C}_4 \mathrm{H}_{10}\right)$ burns completely with $160 \%$ of theoretical air at $20^{\circ} \mathrm{C}, 1 \mathrm{~atm}$, and $90 \%$ relative humidity. Determine (a) the balanced reaction equation. (b) the dew point temperature, in ${ }^{\circ} \mathrm{C}$, of the products, when cooled at $1 \mathrm{~atm}$.
