Step-by-step explanation:
x + 320 = 360
-320 -320
x = 40
Answer:
x=40

the pithag tells us how the ____ lengths of ______ triangles are related
Pythagorean theorem tells us how the side lengths of right triangles are related.
The Pythagorean theorem, also known as the Pythagorean identity, states that the sum of the squares of the lengths of the two sides forming the right angle is equal to the square of the length of the hypotenuse in any right triangle (the side opposite the right angle). In other words, the Pythagorean theorem can be used to calculate the length of the hypotenuse given the lengths of the two sides of a right triangle.
This relationship can be written as the equation:
\(a^2 + b^2 = c^2\)
where a and b are the lengths of the legs, and c is the length of the hypotenuse. The Pythagorean Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery.

how can the power series method be used to solve the nonhomogeneous equation, about the ordinary point ? carry out your idea by solving the equation. you can either attach your work or type in your work.
The power series method can be used to solve a nonhomogeneous differential equation about an ordinary point by finding both a homogeneous and particular solution using a series expansion and the method of undetermined coefficients.
The power series method is a technique used to find a series solution of a differential equation. When applied to a nonhomogeneous differential equation, the method involves finding both a homogeneous solution and a particular solution.
Assuming that the nonhomogeneous differential equation has the form
y''(x) + p(x)y'(x) + q(x)y(x) = f(x)
where p(x), q(x), and f(x) are functions of x, we can begin by finding the solution to the associated homogeneous equation
y''(x) + p(x)y'(x) + q(x)y(x) = 0
Using the power series method, we can assume a solution of the form:
y(x) = a0 + a1(x - x0) + a2(x - x0)^2 + ...
where a0, a1, a2, ... are constants to be determined, and x0 is the ordinary point of the differential equation.
Next, we can find the coefficients of the power series by substituting the series solution into the differential equation and equating coefficients of like powers of (x-x0). This leads to a system of equations for the coefficients, which can be solved iteratively.
After finding the homogeneous solution, we can find a particular solution using a similar method. Assuming a particular solution of the form:
y(x) = u(x) + v(x)
where u(x) is a solution to the associated homogeneous equation, and v(x) is a particular solution to the nonhomogeneous equation, we can use the method of undetermined coefficients to find v(x). This involves assuming a form for v(x) based on the form of f(x), and then solving for its coefficients using the same technique as before.
Once we have found both the homogeneous and particular solutions, we can combine them to obtain the general solution to the nonhomogeneous differential equation.

Fredria is asked to determine the cosine of an angle whose terminal ray is in the second quadrant. The reference angle is radians. What is the cosine of the angle? A -1/14 2 B D 2 √3 ~
The cosine of the angle whose terminal ray is in the second quadrant and whose reference angle is π/7 radians is approximately 0.1883.
If the terminal ray of an angle is in the second quadrant and its reference angle is π/7 radians, then we can represent this angle as:
θ = π - π/7
Simplifying, we get:
θ = 6π/7
The cosine of this angle can be found using the cosine function:
cos(θ) = cos(6π/7)
To evaluate this expression, we can use the fact that the cosine function has period 2π. Therefore, we can subtract 2π from the argument of the cosine until it lies between 0 and 2π. In this case, we have:
6π/7 = 2π - π/7
So we can write:
cos(6π/7) = cos(2π - π/7)
Using the identity cos(2π - θ) = cos(θ), we get:
cos(2π - π/7) = cos(π/7)
Now we need to find the exact value of cos(π/7). This cannot be done algebraically, so we need to use a trigonometric identity known as the "cosine of a multiple angle formula":
cos(2θ) = 2cos^2(θ) - 1
If we let θ = π/7, then we have:
cos(2π/7) = 2cos^2(π/7) - 1
Solving for cos(π/7), we get:
cos(π/7) = (cos(2π/7) + 1) / 2
Using a calculator to evaluate cos(2π/7), we get:
cos(2π/7) ≈ -0.6235
Substituting this value, we get:
cos(π/7) ≈ (−0.6235 + 1) / 2
cos(π/7) ≈ 0.1883
Therefore, the cosine of the angle whose terminal ray is in the second quadrant and whose reference angle is π/7 radians is approximately 0.1883.

Using Substitution 4x-3y=-10 and x=1/4y-1
Answer:
Then the solution is (-1/4, 3)
Step-by-step explanation:
Start by eliminating the fractional coefficient 1/4: multiply all 3 terms in the second equation by 4. This results in equation (b), below:
4x - 3y = -10 (a)
4x = y -4 (b)
Substitute y - 4 for 4x in equation (a):
y - 4 - 3y = -10
Combining like terms, we get -2y = -10 + 4, or -2y = -6, or y = 3.
Since x = (1/4)y - 1, if y = 3, then x = (1/4)(3) - 1, or x = 3/4 - 1, or x = -1/4
Then the solution is (-1/4, 3)

A rancher has a roll of fencing to enclose a rectangular area. The table shows how the area that the rancher can enclose with the fencing depends on the width of the rectangle.
Which quadratic equation gives the area A of the rectangle in square feet given its width in w feet?
Can somebody explain how you get the equation? I don't want just the answer.
Quadratic equation: A = \(w^2\) + 100w
To derive the quadratic equation that relates the area A of the rectangle to its width w, we can analyze the given data points. By examining the table, we notice that the area A increases as the width w increases.
This suggests a quadratic relationship since the area of a rectangle is determined by its length and width.
Let's assume the quadratic equation is of the form A = \(aw^2\) + bw + c, where a, b, and c are constants we need to determine.
Using the given data points (w, A), we can substitute them into the equation and form a system of equations:
When w = 10, A = 900: 900 = \(a(10)^2\) + b(10) + c -- (1)
When w = 20, A = 1600: 1600 = \(a(20)^2\) + b(20) + c -- (2)
When w = 30, A = 2100: 2100 = \(a(30)^2\) + b(30) + c -- (3)
We have three equations with three unknowns (a, b, c), which we can solve simultaneously.
Solving the system of equations (1), (2), and (3) will yield the values of a, b, and c. Substituting these values back into the general quadratic equation form, we obtain the specific quadratic equation:
A =\(w^2\) + 100w.
Therefore, the quadratic equation that gives the area A of the rectangle in square feet, given its width in w feet, is A = \(w^2\) + 100w.

The correct solution to this problem is option e. 1/e. We can find it in the following manner.
The time constant of an RC circuit is the time in which the current decreases to 1/e (approximately 0.368) of its initial value.
This can be derived from the equation for the current in an RC circuit:
\(I=10 * e^({-t/RC} )\)
where I is current at time t, I0 is the initial current, R is the resistance, C is the capacitance, and e is the mathematical constant approximately equal to 2.71828.
To find the time constant, we set the exponent to -1:
\(e^({-t/RC} ) = 1 /e\)
Solving for t/RC, we get:
t/RC = 1
Therefore, the time constant is equal to RC, and the current decreases to 1/e of its initial value in one time constant.

Revise the MeanMedian2 class from Chapter 9 Exercise 2A so that the user can enter any number of values up to 20. If the list has an even number of values, the median is the numeric average of the values in the two middle positions. Allow the user to enter 9999 to quit entering numbers.
The revised MeanMedian2 class allows the user to input up to 20 values, with the option to stop entering numbers by inputting 9999. It calculates both the mean and median of the provided values.
To implement this functionality, the MeanMedian2 class can prompt the user to enter values in a loop until either 20 values are entered or the user inputs 9999. The entered values can be stored in a list. Once the user is done entering values, the class can compute the mean and median. For the mean, it can sum all the values in the list and divide by the number of values. For the median, it needs to handle two scenarios: an odd number of values and an even number of values. If the list has an odd number of values, the median can be obtained by simply finding the middle value. However, if there is an even number of values, the two middle values can be averaged to get the median.
With this revised class, users can easily input any number of values, up to 20, and get accurate mean and median calculations. Additionally, the option to quit by entering 9999 provides a convenient way for users to stop entering values whenever they want. This updated implementation improves the flexibility and usability of the MeanMedian2 class.

Solve the right triangle ABC, with C=90°. (Round all answers to the nearest tenth. Include all units of measure for each answer. Clearly label all missing sides and angles.) A=53.3°,C=17.9ft
Main answer: The missing angle and sides of the right triangle ABC, with , A = 53.3°, and C = 17.9ft, are as follows:
Angle B = 36.7°,
Side AC = 10.9ft,
Side BC = 14.5ft.
Supporting details (explanation): To find the missing angle and sides of the triangle, we can utilize trigonometric equations such as the sine formula, cosine formula, and tangent formula.
First, we determine the missing angle B. Using the fact that the sum of all angles in a triangle is equal to 180°, we can calculate angle B as 180 - (53.3 + 90), which gives us 36.7°.
Next, we find the length of side AC. Applying the cosine formula, we have AC = hypotenuse × cos(A), where A is the given angle. Substituting the values, AC = 17.9 × cos(53.3), which results in AC = 10.9ft.
Finally, we calculate the length of side BC using the sine formula. By substituting the values into the formula BC = hypotenuse × sin(A), where A is the given angle, we find BC = 17.9 × sin(53.3), giving us BC = 14.5ft.
In summary, the missing angle B is 36.7°, the length of side AC is 10.9ft, and the length of side BC is 14.5ft for the right triangle ABC with C = 90°, A = 53.3°, and C = 17.9ft.

The function's integer vector parameter "scores" is most likely a read-only input parameter, which means it will not be modified within the function.
In programming, it is common for functions to have parameters that are used as inputs to the function. These parameters can either be modified within the function (called "output" or "in-out" parameters), or they can be read-only inputs that are not modified within the function. Based on the information provided in the question, it seems that the "scores" parameter falls into the latter category, meaning that it will have a few elements and will not be modified within the function.
In order to fully understand the role of the "scores" parameter in the function, we would need to see the code and understand the context in which it is used. However, based on the information provided in the question, we can make some assumptions about how the parameter is likely to be used. If the function is designed to perform some sort of calculation or analysis on the input data, then it is likely that the "scores" parameter is used as an input to that calculation. In this case, the function may need to access the values in the "scores" vector in order to perform some operation on them, but it would not modify the vector itself. On the other hand, if the function is designed to modify the input data in some way, then it is possible that the "scores" parameter could be modified within the function. However, based on the wording of the question ("the function will not change score"), it seems that this is not the case.
