Is an electron a wave or a particle? Support your answer by citing some experimental results.

Use a change of variables or Table 5.6 to evaluate the following indefinite integrals. Check your work by differentiating

$$\int\left(x^{3 / 2}+8\right)^{5} \sqrt{x} d x$$

The volume of a gas is 7.15 L, measured at 1.00 atm. What is the pressure of the gas in mmHg if the volume is changed to 9.25 L? (The temperature remains constant.)

Expand and simplify if possible: $(\sin \alpha+\cos \alpha)^{2}$

The relative humidity is the ratio (expressed as a percent) of the amount of water vapor in the air to the maximum amount that it can hold at a specific temperature. The relative humidity, R, is found using the following formula: $R=10\left(\frac{4221}{T+459.4}-\frac{4221}{D+459.4}+2\right)$ where T is the air temperature (in $^{\circ} \mathrm{F} )$ and D is the dew point temperature (in $^{\circ} \mathrm{F} ).$ What is the relative humidity if the air temperature and the dew point temperature are the same?

Write the numbers in scientific notation. (A) 0.86 (B) 8.6

One of the main contaminants of a nuclear accident , such as that at Chernobyl , is strontium-90 , which decays exponentially at a rate of approximately $2.5\%$ per year.Write the percent of strontium-90 remaining , $P$, as a function of years ,$t$, since the nuclear accident. [Hint: $100 \%$ of the contaminant remains at $t=0$]

A student is working part time as a hairdresser to pay college expenses. The student may work no more than 24 hours per week. Haircuts cost $25 and require an average of 20 minutes, and permanents cost$70 and require an average of 1 hour and 10 minutes. How many haircuts and or permanents will yield an optimal revenue? What is the optimal revenue?

Use the recursive technique to develop a Gray code for the 16 binary strings of length 4. Then list each of the 16 subsets of the ordered set {w, x, y, z} next to its corresponding binary string.

Draw $\triangle MNP$ with vertices $M(-5, 5) , N(3, 5) ,$ and $P(3, -6).$ Then draw $\triangle QRS$ with vertices $Q( -4, 2), R(7, -6)$ and $S(-4, -6).$ Explain how you know that the triangles are congruent. Then state the congruence.

Determine whether you can construct many, one, or no triangle(s) with the given description. Explain your reasoning. 21. a triangle with angle measures of 50°, 70°, and 100°

A polar equation is given. (a) Express the polar equation in parametric form. (b) Use a graphing device to graph the parametric equations you found in part (a).

$$r = 2 ^ { \theta / 12 } , \quad 0 \leq \theta \leq 4 \pi$$

What is the connection between men and nature in "Of Mice and Men"?

Values of the molar polarization of gascous water at 100 $\mathrm{kP}_{\mathrm{a}}$ as determined from capacitance measurements are given below as a function of temperature.
