Disks/washers about the $\boldsymbol{y}$-axis Let $R$ be the region bounded by the following lines and curves. Use the disk or washer method to find the volume of the solid generated when $R$ is revolved about the y-axis. \

$$y=0, y=\sqrt{x-1}, y=2, x=0$$

In the given figure , point P is at distance d1=4.00 m from particle $1\left(q_1=-2 e\right)$ and distance $d_2=2.00 \mathrm{~m}$ from particle 2 $\left(q_2=+2 e\right)$, with both particles fixed in place. If we bring a particle of charge $q_3=$ $+2 e$ from infinity to $P$, what is the potential energy of the three-particle system?

Consider two solids of equal weight.

Solid A: has no hole from the axis of revolution

Solid B: has a hole from the axis of revolution

Which solid has the greater moment of inertia? Explain.

Given the following data,

Use the linear function to predict when the average price of a ticket will reach$20. Does this estimate seem reasonable?

The table gives the population of Texas for several years.

Use the exponential regression equation to estimate the population of Texas in 2003. How close is the estimate to the actual population of 22,119,000 in 2003?

Assume for the purposes of this problem that to be an alcohol (-ol) or an amine (-amine), the hydroxyl or amino group must be bonded to a tetrahedral ( $s p^3$ hybridized) carbon atom. Write the structural formula of a compound with an unbranched chain of four carbon atoms that is an: Alkanol.

In a scheduling program, we want to check whether two appointments overlap. For simplicity, appointments start at a full hour, and we use military time (with hours 0–24). The following pseudocode describes an algorithm that determines whether the appointment with start time start1 and end time end1 overlaps with the appointment with start time start2 and end time end2.

If start1 > start2
   s = start1
Else
   s = start2
If end1 < end2
   e = endl
Else
   e = end2
If s < e
   The appointments overlap.
Else
   The appointments don’t overlap.

Trace this algorithm with an appointment from 10–12 and one from 11–13, then with an appointment from 10–11 and one from 12–13.

Vas a dar una fiesta. Escribe las direcciones para ir a tu casa desde la escuela. (Hint: Give directions to your house from school.)

modelo - Mi casa está a seis cuadras de la escuela. Camino dos cuadras por la calle Wilson. Vas a ver un banco. Dobla a la izquierda y camina dos cuadras por la calle Metropolitan. Hay una farmacia en la esquina. Dobla a la derecha y camina una cuadra. En la avenida Connecticut, dobla a la izquierda y camina una cuadra más. Yo vivo en la avenida Connecticut 284. Mi casa esta enfrente de la pastelería.

Assume for the purposes of this problem that to be an alcohol (-ol) or an amine (-amine), the hydroxyl or amino group must be bonded to a tetrahedral ( $s p^3$ hybridized) carbon atom. Write the structural formula of a compound with an unbranched chain of four carbon atoms that is an: Alkenamine.

One of the elephants lumbered toward the water hole at f feet per hour for t hours but still arrived 2 hours late. How fast should the elephant have lumbered to have arrived at the water hole on time?

Exponential smoothing for information services hires rate. Consider the monthly information services sector hires rate time series from Exercise 13.46 (pages 693-694). HIRES

(a) Calculate and plot (on a single time plot) exponential smoothing models using smoothing constants of $w=0.1,0.5$, and 0.9 .

(b) Comment on the smoothness of each exponential smoothing model in part (a).

(c) The series ended with the hires rate of June 2014.

For each model in part (a), calculate the forecasts for the hires rate of July 2014.

Suppose that two tanks, 1 and 2, each with a large opening at the top, contain different liquids. A small hole is made in the side of each tank at the same depth $h$ below the liquid surface, but the hole in tank 1 has half the cross-sectional area of the hole in tank 2. What is the ratio R underscore V 1 / R underscore V 2 of the volume flow rates from the two tanks?
