Step-by-step explanation:

You have a right triangle with 60 as the side opposite the 20° angle and you are looking for the adjacent side to that angle.

The trig function to use is the tangent of an angle = opp/adj

Let x = distance from you to the base of plateau

So,  tan 20 = 60/x

x tan 20 = 60

x = 60/tan 20

x = 164.85 m

You must memorize the definitions all of the trig functions so you can do a problem like this one. OK?

The area of the triangle is calculated to be equal to 7.5 square inches.

For any triangle, the area is calculated as half the base multiplied by the height of the triangle, that is;

Area of triangle = 1/2 × base × height

we have the base of the triangle to be 6 inches and the height as 2.5 inches, so we solve for the area as follows:

1/2 × 6 inches × 2.5 inches

6 inches can be divided by 2 to give;

3 inches × 2.5 inches

7.5 square inches

Therefore, the area of the triangle is calculated to be equal to 7.5 square inches

Answer:

a(n) = 7n + 33

Step-by-step explanation:

This sequence is arithmetic meaning it has a common difference. You can find this by subtracting a term from the term that comes after it. In this case, 47-40=7, so 7 is our common difference. Now we can start the formula where a(n)=7n+b, where a(n) is the value of a term and n is the number of the term. Now all we have to do is plug in some numbers.

a(n)=40 when n=1 as the first term of the sequence is 40. This means that 40=7(1)+b, or 40=7+b, or 33=b. This means that the explicit formula is a(n)=7n+33.

The approximate density of the copper is 8.7 grams per milliliters

From the question, we have the following parameters that can be used in our computation:

Mass = 6515 grams

Dimensions: length of 26 cm, height of 8 cm, and width of 36 mm.

The volume is calculated as

Volume = 26 cm * 8 cm * 36 mm

Evaluate

Volume = 748.8 milliliters

The approximate density of the copper is calculated as

Density = mass/volume

So, we have

Density = 6515 grams/748.8 milliliters

Answer:

Either \(c = (2,\, 1,\, (-13) / 7)\) or \(c = (2,\, 1,\, 5)\).

Step-by-step explanation:

The volume of a parallelepiped with sides \(\vec{a}\), \(\vec{b}\), and \(\vec{c}\) is the absolute value of \(\left(\vec{a} \times \vec{b}\right)\, \vec{c}\) (a cross product between the first two sides followed by a dot product with the third side.)

In this example:

\(\begin{aligned} &\vec{a} \times \vec{b} \\ =\; & \begin{bmatrix}3 \\ 1 \\ 2\end{bmatrix} \times \begin{bmatrix}-1 \\ 2 \\ 1\end{bmatrix} \\ =\; & \begin{bmatrix}1 \times 1 - 2 \times 2 \\ 2 \times (-1) - 3 \times 1 \\ 3 \times2 - 1 \times (-1) \end{bmatrix} \\ =\; & \begin{bmatrix} -3 \\ -5 \\ 7 \end{bmatrix}\end{aligned}\).

Given that \(\vec{c} = (2,\, 1,\, m)\) for some unknown parameter \(m\):

\(\begin{aligned}& \left(\vec{a} \times \vec{b}\right)\, \vec{c} \\ =\; & \begin{bmatrix}-3 \\ -5 \\ 7\end{bmatrix}\, \begin{bmatrix}2 \\ 1 \\ m\end{bmatrix} \\ =\; & (-3) \times 2 + (-5) \times 1 + 7 \, m \\ =\; & -11 + 7\, m\end{aligned}\).

The volume of this parallelepiped would be the absolute value \(|-11 + 7\, m|\). For this volume to be equal to \(24\), either \((-11 + 7\, m) = (-24)\), such that \(m = (-13) / 7\), or \((-11 + 7\, m) = 24\), such that \(m = 5\).

Answer:

P'(0,0), E' (3,3), N'(6,3), T'(6,-3), A'(3,-3)

Step-by-step explanation:

1.The dilation is by a scale factor of 3/4 meaning it's less than one, meaning the image will get smaller.

2.To find the new coordinates, multiply 3/4 by each number in the coordinate pair. For example 4x3/4 is 3 making (4,4) (3,3).

The volume of the parallelepiped with sides given by vectors A, B and C is 13 cubic cm, which is the final answer.

The given vectors are:

A = [-4, 3, 2] cm, B = [2,1,3] cm and C= [1, 1, 4] cm

In order to calculate the volume of parallelepiped, we will use vector triple product equation:

Volume = A . (BXC)|, where BXC represents the cross product of vectors B and C.

Step-by-step solution:

We have, A = [-4, 3, 2] cm

B = [2,1,3] cm

C = [1, 1, 4] cm

Now, let's find BXC, using the cross product of vectors B and C.

BXC = | i    j     k|                    2      1     3                            1      1     4        | i    j     k |  = -i + 5j - 3k

Where, i, j, and k are the unit vectors along the x, y, and z-axes, respectively.

The volume of the parallelepiped is given by:

Volume = A . (BXC)|

Therefore, we have: Volume = A . (BXC)

\(Volume = [-4, 3, 2] . (-1, 5, -3)\\Volume = (-4 \times -1) + (3 \times 5) + (2 \times -3)\\Volume = 4 + 15 - 6\\Volume = 13\)

Therefore, the volume of the parallelepiped with sides given by vectors A, B and C is 13 cubic cm, which is the final answer.

Step-by-step explanation:

Because it only considers the worst possible outcomes, the maximin decision criterion has the least downside risk.

Wald's maximin model is a non-probabilistic decision-making model in game theory and decision theory.

It says that while choosing a course of action, the decision-maker should choose the one whose greatest (highest) loss is better than the least (minimum) loss of all other options that are feasible under the current conditions. The approach that maximizes one's own lowest payout is referred to as "maximin" in non-zero-sum games.

When given a choice between numerous options, the maximin approach instructs managers to consider each option's worst-case outcome. This presupposes that each choice has a number of possible outcomes.

The relationship between wavelength and period is such that as the wavelength of a wave increases, its period also increases, given that the wave speed remains constant. This means that longer wavelengths result in longer periods, while shorter wavelengths correspond to shorter periods.

Mathematically, this relationship is expressed through the formula v = λf, where v represents the wave speed, λ is the wavelength, and f is the frequency. Since frequency (f) is the reciprocal of period (T), i.e., f = 1/T, we can rewrite the formula as v = λ(1/T). By rearranging this equation, we can find the relationship between wavelength and period: λ = vT.

In summary, the relationship between wavelength and period is directly proportional, with longer wavelengths resulting in longer periods and vice versa, given a constant wave speed. The mathematical relationship is expressed as λ = vT, where λ is the wavelength, v is the wave speed, and T is the period.

How do we evaluate a double integral over a given region?

To evaluate a double integral over a region, we typically integrate the given function over the region by integrating first with respect to one variable (usually x) and then with respect to the other variable (usually y) while taking into account the specified limits of integration for each variable. This involves evaluating the inner integral followed by the outer integral, which allows us to compute the final value of the double integral.

Body of the Solution:To evaluate the double integral ∫∫ (x − 3y^2) da over the given region, we need to set up and evaluate the integral using the specified limits of integration.

The region R is defined by 0 ≤ x ≤ 6 and 2 ≤ y ≤ 4.

The integral can be written as:

∫∫ (x − 3y^2) da

To evaluate this integral, we integrate with respect to x first, and then with respect to y.

∫∫ (x − 3y^2) da

= ∫[2,4] ∫[0,6] (x − 3y^2) dx dy

Integrating with respect to x, we have:

∫[2,4] [∫[0,6] (x − 3y^2) dx] dy

[1/2 x^2 −3y^2x] evaluated from 0 to 6

[18 − 18y^2] - [0] = 18 − 18y^2

Now, we integrate the resulting expression with respect to y:

∫[2,4] (18 − 18y^2) dy

Integrating, we have:

[18y − 6y^3] evaluated from 2 to 4

Substituting the limits, we have:

(18(4) − 6(4)^3) - (18(2) − 6(2)^3)
