The value of the integral is,

⇒ (81/2) π - (1/10) π* (18 √(3) - 22).

We have a triple integral in cylindrical coordinates, with the limits of integration:

0 ≤ θ ≤ 2π (since θ is not present in the integrand)

0 ≤ x ≤ 3 0 ≤ z ≤ √(9 - x²)

0 ≤ y ≤ √(9 - x² - z²)

Converting the integrand to cylindrical coordinates, we have:

[tex]1(x^{2} + y^{2} + z^{2} )^{1/2} = r[/tex]

So the integral becomes:

∫(0 to 2π) ∫(0 to 3) ∫(0 to √(9 - x²)) ∫(0 to √(9 - x² - z²)) r dy dz dx

We can evaluate the innermost integral with respect to y:

∫(0 to √(9 - x² - z²)) r dy = r √(9 - x² - z²)

Then we can integrate with respect to z:

∫(0 to √(9 - x²)) r √(9 - x² - z²) dz = (1/2) πr (9 - x²)

Finally, we can integrate with respect to x:

∫(0 to 3) (1/2) πr (9 - x²) dx = (27/2) π∫(0 to 3) r dx - (1/2) π∫(0 to 3) r * x²dx

The first integral is simply the volume of a cylinder of height 3 and radius 3, which is (27/2) π3² = (81/2)π.

For the second integral, we can convert back to Cartesian coordinates and use the substitution u = 9 - x² - z²:

∫(0 to 3) r x² dx = ∫(0 to 9) √(u) (9 - u) du = (2/5) [tex]u^{5/2}[/tex] - (1/3) [tex]u^{3/2}[/tex]] 0 to 9

= [tex]\frac{2}{5} 9^{5/2} - \frac{1}{3} 9^{3/2}[/tex]

Substituting this result back into the original integral, we have:

(27/2) π3 - (1/2) pi [ [tex]\frac{2}{5} 9^{5/2} - \frac{1}{3} 9^{3/2}[/tex]] = (81/2) pi - (1/10) π(18 √(3) - 22)

So, the value of the integral is,

To find the point on the plane nearest to the origin, we need to minimize the distance between the origin and any point on the plane. We can use the formula for the distance between a point and a plane. The point on the plane nearest to the origin is (2, 12, 2).

distance = |ax + by + cz + d| / sqrt(a^2 + b^2 + c^2)

where (x, y, z) is any point on the plane, and a, b, c, and d are the coefficients of the plane equation.

In our case, the plane equation is 4x - y + 4z = 40, so a = 4, b = -1, c = 4, and d = -40. The distance between the origin and any point on the plane is:

distance = |4x - y + 4z - 40| / sqrt(4^2 + (-1)^2 + 4^2)

We want to minimize this distance, so we need to find the point on the plane that makes the distance as small as possible. To do this, we can use Lagrange multipliers:

Let f(x, y, z) = (x^2 + y^2 + z^2) be the function we want to minimize subject to the constraint 4x - y + 4z = 40. We can write this as:

grad(f) = λ grad(g)

where grad(f) = <2x, 2y, 2z> and grad(g) = <4, -1, 4>. Solving for x, y, z, and λ, we get:

x = 2, y = 12, z = 2, λ = 8 / sqrt(33)

Therefore, the point on the plane nearest to the origin is (2, 12, 2).

To find the point on the plane 4x - y + 4z = 40 nearest to the origin, we can use the formula for the distance between a point and a plane: D = |Ax + By + Cz + D| / √(A² + B² + C²).

In this case, A = 4, B = -1, C = 4, and D = -40. Let's plug in the origin (0, 0, 0) for (x, y, z):

D = |(4*0) - (1*0) + (4*0) - 40| / √(4² + (-1)² + 4²)
D = |-40| / √(16 + 1 + 16)
D = 40 / √33

Now, we use the normal vector (4, -1, 4) and multiply it by the distance D to find the nearest point (x, y, z):

x = (4 * 40) / √33
y = (-1 * 40) / √33
z = (4 * 40) / √33

The nearest point (x, y, z) on the plane 4x - y + 4z = 40 to the origin is approximately (4.94, -1.24, 4.94).

To identify the surface whose equation is given as ρ²(sin²(φ) sin²(θ) + cos²(φ)) = 81, we can follow these steps:

Rewrite the equation
We have the equation: ρ²(sin²(φ) sin²(θ) + cos²(φ)) = 81

Isolate ρ²
We can rewrite the equation as: ρ² = 81 / (sin²(φ) sin²(θ) + cos²(φ))

Find ρ
Take the square root of both sides to find ρ: ρ = √(81 / (sin²(φ) sin²(θ) + cos²(φ)))

We can use the properties of the normal distribution to calculate the probability that the total volume shipped is more than 100,000 ft3.

Assuming that the xis are independent with each one having a normal distribution, the total volume shipped can be modeled as the sum of these individual normal distributions. Since the sum of independent normal distributions is also a normal distribution, we can use the properties of the normal distribution to calculate the probability that the total volume shipped is more than 100,000 ft3.

To do this, we need to find the mean and variance of the sum of the xis. The mean of the sum is simply the sum of the means of the individual distributions, while the variance of the sum is the sum of the variances of the individual distributions.

Once we have the mean and variance of the sum, we can standardize the distribution and use a normal probability table or calculator to find the probability that the total volume shipped is more than 100,000 ft3.

In general, the probability of the sum of independent normal distributions exceeding a certain value depends on the number of distributions being summed, their means and variances, and the level of significance chosen for the test. Therefore, we need to specify these parameters to calculate the desired probability.

Step-by-step explanation:

The y-intercept is approximately 191.1. The correct option is (B).

To compute the y-intercept, we need to use the equation of the regression line, which is:

y = a + bx

where a is the y-intercept, b is the slope, x is the independent variable (in this case, x-bar), and y is the dependent variable (in this case, y-bar).

The formula for the slope of the regression line is:

b = r * (sy/sx)

where r is the correlation coefficient, sx is the standard deviation of x, and sy is the standard deviation of y.

Substituting the given values, we get:

b = 0.341 * (37/12) = 1.05025

Now, we can use the formula for the y-intercept:

a = y-bar - b * x-bar

Substituting the given values, we get:

a = 251 - 1.05025 * 57 = 191.10925

Therefore, the y-intercept is approximately 191.1.

Kendra is training for a marathon. Next week, Kendra will run 26.22 miles.

Kendra's current distance of running 22.8 miles each Saturday indicates a good level of endurance and fitness. However, to prepare for a marathon, she will need to gradually increase her running distance. Kendra has planned to increase her distance by 15% from her current distance. To calculate her new distance, we can use the following formula:

New distance = Current distance + (Percentage increase × Current distance)

Plugging in the values, we get:

New distance = 22.8 + (15% × 22.8) = 26.22 miles (rounded to two decimal places)

Kendra's new distance of 26.22 miles represents a significant increase from her current distance. It is important to note that Kendra should continue to gradually increase her running distance over time to avoid injury and improve her endurance. She can also incorporate other forms of exercise, such as strength training and cross-training, to complement her running and improve overall fitness.

The radius of the circle circumscribing the isosceles triangle is :

(a) 20sqrt(2).

To find the radius of the circle circumscribing the isosceles triangle, we need to use the fact that the perpendicular bisectors of the sides of the triangle intersect at the center of the circle. Since the triangle is isosceles, the perpendicular bisector of the base will also be an altitude, so it will intersect the base at its midpoint. Let's call this point M.

First, we can use the Pythagorean theorem to find the height of the triangle. If we draw an altitude from the vertex opposite the base to the midpoint of the base, we get two right triangles that are congruent by the hypotenuse-leg congruence theorem. Let's call the height h. Then:

h^2 + 24^2 = 40^2
h^2 = 40^2 - 24^2
h = sqrt(40^2 - 24^2)
h = 32

Now we can find the distance from the center of the circle to point M, which is the radius of the circle. Let's call this distance r. Since M is the midpoint of the base, its distance from each endpoint is 24. We can use the Pythagorean theorem again to find r:

r^2 = h^2 + 24^2
r^2 = 32^2 + 24^2
r^2 = 1152
r = sqrt(1152)
r = 12sqrt(8)
r = 24sqrt(2)

The solution to the initial value problem is x(t) = 4/27 sin(3t).

We have solved the initial value problem x" + 9x = 12 sin(3t), x(0) = x'(0) = 0 and graphed the solution to confirm the phenomenon of pure resonance.

First, we need to solve the differential equation x" + 9x = 12 sin(3t) using standard techniques from differential equations. We can begin by assuming a solution of the form x(t) = A sin(3t) + B cos(3t), where A and B are constants to be determined. Taking the first and second derivatives of x(t), we find

=> x'(t) = 3A cos(3t) - 3B sin(3t) and x''(t) = -9A sin(3t) - 9B cos(3t).

Substituting these expressions into the differential equation, we obtain

=> -9A sin(3t) - 9B cos(3t) + 9A sin(3t) + 9B cos(3t) = 12 sin(3t).

Simplifying, we get 0 = 12 sin(3t), which implies that sin(3t) = 0.

This has solutions at t = 0, pi/3, 2pi/3, pi, etc.

These are the resonant frequencies of the system, where the external force is in phase with the natural frequency of the system.

To find the constants A and B, we can use the initial conditions x(0) = 0 and x'(0) = 0. Substituting t = 0 into the expressions for x(t) and x'(t), we get A = 0 and B = 0.

Therefore, the solution to the initial value problem is x(t) = 4/27 sin(3t).

Now let's graph the solution to confirm the phenomenon of pure resonance. We can use a graphing calculator or software to plot the function x(t) = 4/27 sin(3t) over a suitable range of t. We can also graph the external force 12 sin(3t) to see how it compares to the motion of the system.

The formula to find the amount A(t) of money after t years with principal P, annual interest rate r compounded continuously is:

A(t) = Pe^(rt)

where e is the mathematical constant approximately equal to 2.71828.

To find how long it takes for an investment to double, we need to find the time t such that A(t) = 2P, where P is the initial investment.

In this case, P = $1000, and r = 8% = 0.08.

(2x+1)(2x-1) as a polynomial in standard form is 4x^2 - 1. The leading coefficient is 4, which tells us that the graph of this function opens upwards. The degree of the polynomial is 2, which means that the graph is a parabola.

The expression (2x+1)(2x−1) can be expanded using the FOIL method, which stands for "First, Outer, Inner, Last". This method involves multiplying each term in the first expression by each term in the second expression, and then combining like terms.

Using this method, we can find that:

(2x+1)(2x−1) = (2x)(2x) + (2x)(−1) + (1)(2x) + (1)(−1)

= 4x^2 − 2x + 2x − 1

= 4x^2 − 1

Thus, we have expanded the expression and simplified it to the standard form of 4x^2 - 1. This form is useful because it allows us to easily identify the leading coefficient and the degree of the polynomial, which are both important properties of a quadratic function. The leading coefficient is 4, which tells us that the graph of this function opens upwards. The degree of the polynomial is 2, which means that the graph is a parabola.

Step-by-step explanation:

The area of a horizontal cross section of a cylinder is the same as the area of the circular base of the cylinder.

To find the area of the circular base of the cylinder, we first need to find the radius of the circle.

The formula for the circumference of a circle is C = 2πr, where r is the radius.

Given the circumference of the cylinder is 131.88 cm, and using 3.14 for π, we can use circumference formula to find the radius of the circular base:

[tex]\begin{aligned}C &= 2\pi r\\\\\implies 131.88 &= 2 \cdot 3.14 \cdot r\\\\131.88 &= 6.28 r\\\\\dfrac{131.88}{6.28} &= \dfrac{6.28 r}{6.28}\\\\21&=r\\\\r&=21\; \sf cm\end{aligned}[/tex]

Substitute the found value of r into the formula for the area of a circle to find the area of a horizontal cross section of the cylinder:

Step-by-step explanation:

18.

The discount is 15%.

The original price is $30.

The discount is 15% of $30.

To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100.

15% of $30 = 15% × $30 = 0.15 × $30 = $4.50

19.

The discount is 25%.

The original price is $24.

The discount is 25% of $24.

To find a percent of a number, multiply the percent by the number. Change the percent to a decimal by dividing the percent by 100.

25% of $24 = 25% × $24 = 0.25 × $24 = $6

The discount is $6.

Now we subtract the amount of the discount, $6, from the original price.

$24 - $6 = $18

Answer: $18

Rounding to two decimal places, the minimum acceptable weight of a box of cookies is 15.42 ounces.

weight of the boxes of cookies follows a normal distribution with a mean of 16 ounces and a standard deviation of 0.25 ounces.

To find the minimum acceptable weight of a box of cookies, we need to find the value that corresponds to the 1st percentile of the normal distribution.

Using a standard normal distribution table or calculator, we find that the z-score corresponding to the 1st percentile is approximately -2.33.

We can use the formula z = (x - μ) / σ, where x is the minimum acceptable weight, μ is the mean, and σ is the standard deviation, to solve for x.

Plugging in the values, we get:

-2.33 = (x - 16) / 0.25

Solving for x, we get:

x = -2.33 * 0.25 + 16 = 15.4175
