The surface area of a conical grain storage tank that has a height of 42 meters and a diameter of 24 meters is 1,670.5 square meters.

The surface area of a cone is calculated using the following formula:

Surface area = πr² + πrl, where π is approximately equal to 3.14, r is the radius of the base of the cone, and l is the slant height of the cone.

In this problem, we are given that the height of the cone is 42 meters and the diameter of the base is 24 meters. The radius of the base is half of the diameter, so the radius is 12 meters. The slant height of the cone can be calculated using the Pythagorean theorem.

l² = 12² + 42²

l² = 1764

l = 42.01 meters

The surface area of the cone is then calculated as follows:

Surface area = πr² + πrl

Surface area = 3.14 * 12² + 3.14 * 12 * 42.01

Surface area = 1,670.5 square meters

Step-by-step explanation:

Negative square roots are complex numbers.

Answer:

A

Step-by-step explanation:

We know that ∠\(ABE\) ≅ ∠\(DBC\) because they are vertical angles, so that's one pair of congruent angles. However, we can't compare ∠\(BAE\) and ∠\(DCB\) as they have different measures, so we'll have to find the measure of either ∠\(AEB\) or ∠\(BDC\). Let's go with the former. Using the fact that the sum of the measures of the interior angles of a triangle is \(180\)°, we know that \(m\)∠\(AEB=180-(53+42)=180-95=85\)°. Now, we know that ∠\(AEB\) ≅ ∠\(DCB\) because their measures are equal. That's another pair of congruent angles. Therefore, the angles are similar by \(AA\). Hope this helps!

The resolving power of a 4x objective with a numerical aperture of 0.275 is approximately 0.57 micrometers.

The resolving power (RP) of an objective lens can be calculated using the formula: RP = λ / (2 * NA), where λ is the wavelength of light and NA is the numerical aperture.

Assuming a typical wavelength of visible light (λ) is 550 nanometers (0.55 micrometers), we substitute the values into the formula: RP = 0.55 / (2 * 0.275).

Performing the calculations, we find: RP ≈ 0.55 / 0.55 = 1.

Therefore, the resolving power of a 4x objective with a numerical aperture of 0.275 is approximately 0.57 micrometers.

Answer:

When x=4, ln x-ln y=y-4, so ln 4-ln 4=4-4, which is true. Therefore, when x=4, y=4, and dy/dx=0.

Step-by-step explanation:

So, when x = 4, the value of the differentiable function dy/dx is 0.

A differentiable function of one real variable is one that has a derivative at each point in its domain. In other words, a differentiable function's graph has a non-vertical tangent line at each interior point in its domain.

Here,

Given the equation ln x - ln y = y - 4, we can rearrange it to get ln(x/y) = y - 4. Taking the derivative of both sides with respect to x using the chain rule:

d/dx (ln(x/y)) = d/dx (y - 4)

(1/x) (dx/dx) - (1/y) (dy/dx) = dy/dx

dy/dx = (1/y) (dx/dx) + (1/x) (dy/dx) = (1/y) + (1/x) (dy/dx)

Rearranging and solving for dy/dx:

(x/y) (dy/dx) = (1/y) - (1/x)

dy/dx = (x/y^2) (1/x - 1/y) = (x/y^2) (1/x - 1/y)

We can substitute x = 4 and y = 4 into the expression to find the value of dy/dx when x = 4:

dy/dx = (4/16) (1/4 - 1/4) = 0

So, the value of differentiable function dy/dx when x = 4 is 0.

To determine the value of a+c, we can analyze the behavior of the function y = (ax+b)/(x+c) as x approaches infinity and negative infinity.

Given that the graph has a horizontal asymptote at y = 2, it means that as x approaches infinity or negative infinity, the function approaches a constant value of 2. In other words, the numerator (ax+b) must have the same degree as the denominator (x+c) for the asymptote to exist.

Since the denominator (x+c) has a vertical asymptote at x = -3, it means that (x+c) approaches zero as x approaches -3. This implies that c = -3.

To match the degree of the numerator and denominator, we need to have a degree-1 polynomial in the numerator. Since the numerator is ax + b, the degree of the numerator is 1 only if a = 0.

Therefore, we have a = 0 and c = -3. Thus, a + c = 0 + (-3) = -3.

Therefore, the correct answer is: a + c = -3.

To find the volume of the solid, we need to subtract the volume of the hemispherical hole from the volume of the cylinder.

The diameter of the hemispherical hole is equal to the thickness of the rim plus the diameter of the cylinder, which is 3 + 2r, where r is the radius of the cylinder.

Using the Pythagorean theorem, we can find the radius of the cylinder:

r^2 + (12/2)^2 = (11.5/2)^2

r^2 + 36 = 33.0625

r^2 = 33.0625 - 36

r^2 = -2.9375

r = sqrt(-2.9375) (ignoring the imaginary solution)

r ≈ 1.71

Therefore, the diameter of the hemispherical hole is 3 + 2r ≈ 6.42 inches.

The height of the cylinder is 12 inches, so its volume is:

V_cylinder = πr^2h

V_cylinder = π(1.71)^2(12)

V_cylinder ≈ 116.71 cubic inches

The volume of the hemispherical hole is:

V_hemisphere = (2/3)π(0.5d/2)^3

V_hemisphere = (2/3)π(0.5(6.42)/2)^3

V_hemisphere ≈ 18.67 cubic inches

Therefore, the volume of the solid is:

V_solid = V_cylinder - V_hemisphere

V_solid ≈ 116.71 - 18.67

V_solid ≈ 98.04 cubic inches

So the volume of the solid is approximately 98.04 cubic inches.

In order to calculate the new divisor for a 3-for-4 reverse stock split, we must first calculate the new share price for Able. Since 3/4 of the shares are being replaced with just 1/4 of the old shares, the new price for Able will be $111 (3 x $37 = $111).

The divisor is used to calculate the new index value by dividing the sum of the new share prices by the divisor. Therefore, the new divisor will be 1.33 ($111 + $312 + $94 = $517 / 1.33 = $389.28). This is because the new share prices will total $517 and when you divide that by the divisor, the index value will be $389.28.

The solution to the system of Equations is x = 1 and y = -2.

Binh was solving a system of equations using the graphing method. This method involves graphing the given equations and finding the point where the graphs intersect. In this case, Binh incorrectly graphed the equation y = x - 3.

To solve the system correctly, Binh should follow these steps:

1. Rewrite the equation, if needed, in the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. The given equation, y = x - 3, is already in this form.

2. Determine the slope (m) and the y-intercept (b) of the equation. For the equation y = x - 3, the slope (m) is 1 and the y-intercept (b) is -3.

3. Graph the equation by first plotting the y-intercept on the y-axis and then using the slope to find additional points on the graph.

4. Repeat steps 1-3 for the second equation in the system.

5. Observe where the graphs intersect. This point represents the solution to the system of equations.

In this case, Binh should have found the point of intersection to be (1, -2). This means that the solution to the system of equations is x = 1 and y = -2.

The stationing of the end of the excavation is Station 2+080.

The volume of fill by end area method is 1440 cubic meters.

The volume of excavation by end area is 1080 cubic meters.

We have,

The stationing of the end of excavation can be determined by adding the given sections to the starting station.

Assuming the starting station is Station 2+020, the end of excavation would be at Station 2+080 (given as Station 2+020 + 60 meters).

To find the volume of fill by end area method, we need to calculate the area of the end section and multiply it by the distance between the start and end stations.

Given that the base for fill is 12 meters and the sideslope for fill is 2:1, the area of the end section can be calculated as follows:

Area of end section = (Base for fill) * (Sideslope for fill)

Area of end section = 12 * (2/1) = 24 square meters

Now, multiply the area of the end section by the distance between the start and end stations (60 meters) to find the volume of fill:

Volume of fill = Area of end section * Distance

Volume of fill = 24 * 60 = 1440 cubic meters

Therefore, the volume of fill by end area method is 1440 cubic meters.

Similarly, to compute the volume of excavation by end area, we calculate the area of the end section (base for cut * sideslope for cut) and multiply it by the distance between the start and end stations. Given that the base for cut is 12 meters and the sideslope for cut is 1.5:1, the area of the end section can be calculated as follows:

Area of end section = (Base for cut) * (Sideslope for cut)

Area of end section = 12 * (1.5/1) = 18 square meters

Multiply the area of the end section by the distance between the start and end stations (60 meters) to find the volume of excavation:

Volume of excavation = Area of end section * Distance

Volume of excavation = 18 * 60 = 1080 cubic meters

Therefore, the volume of excavation by end area is 1080 cubic meters.

Thus,

The stationing of the end of the excavation is Station 2+080.

The volume of fill by end area method is 1440 cubic meters.

Answer:

\(m\angle Y=40^\circ\)

Step-by-step explanation:

Suppose we have a triangle WXY whose internal angles are:

\(m\angle W = 10x+17\)

\(m\angle X=2x-9\)

\(m\angle Y=3x+7\)

The sum of the measures of the angles must be 180°, thus:

\(10x+17 + 2x-9+3x+7=180\)

Simplifying:

15x + 15 = 180

Subtracting 15:

15x = 165

Dividing by 15:

x = 11

Thus, the measure of angle Y is

\(m\angle Y=3x+7=3*11+7=33+7=40\)

\(\mathbf{m\angle Y=40^\circ}\)

Answer:

MO, NO, MN

Step-by-step explanation:

First, we can identify this triangle as a right triangle, as given by the square next to the O. Next, we know that a right angle is equal to 90 degrees, and the sum of the angles of a triangle is equal to 180 degrees.

Therefore,

∠M + ∠O + ∠N (the angles of the triangle) = 180

49 + 90 + ∠N = 180

139 + ∠N = 180

subtract both sides by 139 to isolate the variable

∠N = 41

Therefore, ∠N is 41 degrees.

In a triangle, given the angles, we know that the side opposite the smallest angle is the side with the smallest length and so on.

Our angle lengths are

41, 49, and 90 degrees in order.

Therefore, the side opposite the largest angle (90 degrees, or ∠O) is the longest side. This is MN. Similarly, ∠N is the smallest angle, and the side opposite of that (MO) is the shortest side. This leaves NO to be in the middle

The value of f'(5) is 30z. The value of f'(2) is \(72x^2(3x^3 + 2)\) from the the power rule and the chain rule.

To find the derivative of f(x), we need to apply the power rule and the chain rule. Let's break down the calculation for each case.

1. f(x) = 9z^2 + 1/(3x + 4)

To find f'(5), we consider z as a constant. Taking the derivative of 9z^2 with respect to x gives us 0. The derivative of 1/(3x + 4) with respect to x can be found using the chain rule, which states that d(u/v)/dx = (v * du/dx - u * dv/dx)/v^2. In this case, u = 1 and v = 3x + 4. Applying the chain rule, we find that f'(5) = 0 - 1 * 3/\((3x + 4)^2 = -3/(3x + 4)^2\).

2. f(x) = \((3x^3 + 2)^2\)

To find f'(2), we apply the chain rule. We let u = \(3x^3 + 2\ and\ v = u^2\). Taking the derivative of u with respect to x gives us du/dx = 9x^2, and the derivative of v with respect to u is dv/du = 2u. Applying the chain rule, we have f'(2) = du/dx * dv/du = \(9x^2 * 2(3x^3 + 2) = 18x^2(3x^3 + 2)\).

Therefore, the value of f'(5) is -3/(3x + 4)^2, and the value of f'(2) is \(18x^2(3x^3 + 2)\).

Since the first name drawn is thrown away, it reduces the pool of names from which the second name can be drawn. As a result, the probability of your name being drawn next changes based on the outcome of the first event.

Dependent events occur when the outcome of one event affects the probability of the next event.
