question content area top part 1 express the following angular speed in radians per second. 14 revolutions per second
The angular speed of 14 revolutions per second is equal to 87.96 radians per second.
Angular speed is a measure of how fast an object is rotating or revolving around an axis. It is typically measured in units of angular displacement per unit of time, such as degrees per second, revolutions per minute (RPM), or radians per second.
To convert angular speed from revolutions per second (RPS) to radians per second (RAD/s), we can use the following formula:
Angular speed (RAD/s) = 2π x Revolutions per second (RPS)
Given that the angular speed is 14 revolutions per second, we can substitute this value into the formula:
Angular speed (RAD/s) = 2π x 14 RPS
Angular speed (RAD/s) = 87.96 RAD/s
So, 14 revolutions per second is equivalent to 87.96 radians per second.

What are m and b in the linear equation, using the common meanings of m and b?
2 + 3x + 5 - 2x = y
The values of m and b on the linear equation:
2 + 3x + 5 - 2x = y
are
m = 1
b = 7
How to find the values of m and b?A general linear equation can be written as in the slope-intercept form as:
y = m*x + b
Where m is the slope and b is the y-intercept.
Here we have the linear equation
2 + 3x + 5 - 2x = y
Now we want to write this in the slope-intercept form, to do so, we just need to simplify the left side, then we will get:
2 + 3x + 5 - 2x = y
(2 + 5) + (3x - 2x) =y
7 + x = y
Then the linear equation is:
y = 1*x + 7

A 54-foot long wire will be attached to the top of a pole for support, and will be pulled tight and anchored to the ground.
If the wire makes a 13 degree angle with the ground, how tall is the pole?
The height of the pole used in the question is; 12.15 ft
How to use trigonometric ratios?The 3 main trigonometric ratios are;
sin x = opposite/hypotenuse
cos x = adjacent/hypotenuse
tan x = opposite/adjacent
Now, since the guy wire makes an angle of 13 degrees with the ground, it means the guy wire will be the hypotenuse of the right angle triangle and the height of the pole which we will label as h will be the opposite side of the triangle. Thus;
height/54 = sin 13

A logarithm is an operation used to determine the exponent of a given base number.
What is logarithm?
A logarithm is a mathematical function that describes the relationship between the power to which a number (called the base) must be raised, and the resulting value. The logarithm of a number is the power to which the base must be raised to produce that number.
Start by moving the logarithm to the left-hand side of the equation: log(x²-15) = log(2x)
Next, use the property of logarithms that log(a/b) = log(a) - log(b) to get x²-15 = 2x
then you can simplify the equation by subtracting 2x from both sides x²-2x-15=0
then factor the equation to get (x - 5)(x + 3) = 0
Finally, use the Zero Product Property to solve for x. The solutions will be x = 5 or x = -3

What is a matrix?A rectangular array of numbers, symbols, or expressions set up in rows and columns is known as a matrix. They are employed in a wide variety of mathematical disciplines and contexts, including calculus, statistics, physics, and engineering, as well as linear algebra. Matrices are an essential tool for solving systems of linear equations and representing linear transformations since they may be added, subtracted from, and multiplied by other matrices.
The matrix multiplication of [2 1 0] and [1 -1 2 -1 -2 1 0 1 1] is:
[2 1 0] x [1 -1 2 -1 -2 1 0 1 1] = [2(1) + 1(-1) + 0(2), 2(-1) + 1(-2) + 0(1), 2(0) + 1(1) + 0(1)]

g suppose that w(t) is a real-valued signal. prove that its fourier transform magnitude is symmetric around f
Since the Fourier transform of a real value signal is the product of the even cosine transform and the odd sine transform, it is conjugate symmetric and consequently symmetric about the frequency 0.
A real-valued signal's Fourier transform is a conjugate symmetric function, which means it is symmetric about frequency 0. This is demonstrated by the fact that a real-valued signal's Fourier transform may be expressed as the product of its cosine and sine transforms:
F(w) = Fc(w) plus Fs (w)
Where the cosine and sine transforms, respectively, are denoted by Fc(w) and Fs(w). Both the sine and cosine transforms are symmetric about the frequency zero because the sine transform is an odd function and the cosine is an even function. As a result, a real-valued signal's Fourier transform also exhibits symmetry near frequency 0.

How to order the functions' average ratesFrom the question, we have the following parameters that can be used in our computation:
The functions
The interval is given as
4 ≤ x ≤ 7
And the average rate is calculated as
Rate = (f(x₂) - f(x₁))/(x₂ - x₁)
So, we have
f(x) rate = (10 + 10)/(7 - 4) = 6.67
g(x) rate = (19 - 7)/(7 - 4) = 4
For h(x), we have
h(7) = 7^2 - 9 * 7 + 5 = -9
h(4) = 4^2 - 9 * 4 + 5 = -15
So, we have
h(x) rate = (-15 + 9)/(7 - 4) = -2

Use c for the additional amount (in dollars) Maria will spend.
Write your answer as an inequality solved for c.
Answer:
Maria is able to spend less than $12.
C < 12
Step-by-step explanation:
If Maria has already spent 17 dollars, that means she has 12 dollars left. C cannot be greater than 12. It has to be less.
So think of this C < $12
So if we do the total on one side and the $17 and C on the other side of inequality we get
C + 17 < 29
It cannot be equal to 29 so that's why we don't use a less than or equal to symbol.

To find the inverse of the function, swap x and y:
[tex]\implies x=-4y^2+3[/tex]
Rearrange the equation to isolate y:

[tex]\implies y^2=-\dfrac{x-3}{4}[/tex]
[tex]\implies y^2=\dfrac{3-x}{4}[/tex]
As the domain and range of function a(x) are unrestricted, the inverse relation is a “sideways” parabola and therefore it is not a function, since it fails the vertical line test.
Part bGiven function:
[tex]c(x)=(x-5)^2+2,\;\;x\geq5[/tex]
As the domain of function c(x) is restricted to x ≥ 5, the range is also restricted.
Range: c(x) ≥ 2To find the inverse of the function, swap x and y:
[tex]\implies x=(y-5)^2+2[/tex]
Rearrange the equation to isolate y:
[tex]\implies x-2=(y-5)^2[/tex]
[tex]\implies \pm\sqrt{x-2}=y-5[/tex]
[tex]\implies y=5\pm\sqrt{x-2}[/tex]
As the domain of function c(x) is restricted to x ≥ 5 then:
[tex]\implies y=5+\sqrt{x-2}[/tex]
Replace y with c⁻¹(x):
[tex]\implies c^{-1}(x)=5+\sqrt{x-2}[/tex]
The domain of the inverse of a function is the same as the range of the original function. Therefore, the domain of the inverse function is restricted to x ≥ 2.
Part cGiven function:
[tex]f(x)=\dfrac{5x}{3x+2}[/tex]
To find the inverse of the function, swap x and y:
[tex]x=\dfrac{5y}{3y+2}[/tex]
Rearrange the equation to isolate y:
[tex]\implies x(3y+2)=5y[/tex]
[tex]\implies 3xy+2x=5y[/tex]
[tex]\implies 3xy-5y=-2x[/tex]
[tex]\implies y(3x-5)=-2x[/tex]

Replace y with f⁻¹(x):

[-(x+3)/2] -1, when x is greater than or equal to -3,
and
Yes, the piecewise functions that coincide with the given function are [(x + 3)-1, when x is greater than or equal to 3, [(x-3)/2] -1, when x is less than 3, [(x+3)/2] -1, when x is greater than -3, and -(x+3)/2] -1, when x is greater than or equal to -3.
Piecewise functionThe piecewise functions that coincide with the given function are as follows: when x is greater than or equal to 3, the piecewise function is (x + 3)-1; when x is less than 3, the piecewise function is (x-3)/2 -1; when x is greater than -3, the piecewise function is (x+3)/2 -1; and when x is greater than or equal to -3, the piecewise function is -(x+3)/2 -1.This means that, depending on the value of x, the resulting value of the function f(x) = |₂³| − 1 will be different.For example, when x is equal to 3, then f(x) = 0; when x is equal to -3, then f(x) = -2; and when x is equal to 1, then f(x) = -1.Thus, the piecewise functions correctly express the given function, as they correctly capture the different values of f(x) for different values of x.No, the piecewise functions that coincide with the given function are[(x + 3)-1, when x is greater than or equal to 3,[(x-3)/2] -1, when x is less than 3,[-(x-3)/2] -1, when x is less than or equal to -3,[(x-3)/2] -1, when x is greater than -3.To learn more about Piecewise function refer to:

What is fraction?
Fractions are a way of representing part of a whole. They are written as two numbers separated by a slash. The top number is called the numerator, and the bottom number is called the denominator. For example, in the fraction 1/2, 1 is the numerator and 2 is the denominator. This fraction represents one part of a total of two parts.
Mrs. Carter's famous peanut butter cookies call for 1 cup of peanut butter for every 1/2 of a cup of oil. Today, she wants to make a huge batch with 1 cup of oil.
From the above question:
1/2 cup of oil = 1 cup of peanut butter
1 cup of oil = x
Cross Multiply
1/2x = 1 × 1
x = 1 ÷ 1/2
x = 1 × 2/1
x = 2 cups of peanut butter.
Therefore, for huge batch with 1 cup of oil, she should use 2 cups of peanut butter.
