Answer:
y = -5/7x - 2
Step-by-step explanation:
The slope intercept form is y = mx + b
5x + 7y = -14
Subtract 5x both sides
7y = -5x - 14
Divided by 7 both sides
y = -5/7x - 2
So, the answer is y = -5/7x - 2
What is the inverse of the statement?
A number that has exactly two distinct factors is prime.
If a number has exactly two distinct factors, then the number is prime.
If a number does not have exactly two distinct factors, then the number is not prime.
If a number is not prime, then the number does not have exactly two distinct factors.
If a number is prime, then the number has exactly two distinct fac
The inverse of the statement is "If a number does not have exactly two distinct factors, then the number is not prime." Thus Option 2 is the answer.
When a conditional statement is reversed, the hypothesis and conclusion are both negated. The hypothesis in the original statement is "a number with exactly two distinct factors," while the conclusion is "is prime."
To make the inverse, we negate both sections. "A number does not have exactly two distinct factors" is the antonym of "A number that has exactly two distinct factors." "Is not prime" is the opposite of "is prime."
As a result, the inverse statement is "If a number does not have exactly two distinct factors, then the number is not prime."
It's crucial to remember that a statement's inverse could or might not be accurate. In this instance, the inverse is true since the definition of a prime number is incompatible with the fact that a number has more than two components if it has more than exactly two different factors.

Yes, function notation can be used to add two functions. we can compose the two functions to get the velocity as a function of time.
To add two functions f(x) and g(x), we simply add their output values for the same input value x. So, (f+g)(x) = f(x) + g(x).
In the given example, f(x) = 3x + 2 and g(x) = 4x. Therefore, (f+g)(x) = 3x + 2 + 4x = 7x + 2.
We can also compose functions, such as f(g(x)) which means applying function g to x and then applying function f to the result. In the given example, f(g(x)) = f(4x) = 3(4x) + 2 = 12x + 2.
Function composition can be useful in situations where we want to model complex systems as a series of simpler functions. For example, in physics, the position of an object may be modeled as a function of time, and the velocity of the object may be modeled as the derivative of the position function with respect to time. In this case, we can compose the two functions to get the velocity as a function of time.

An assumption of the linear model of communication is the belief that communication is a one-way process where a sender transmits a message to a receiver through a channel. This model assumes that communication is a linear process where the sender encodes a message, which is then sent through a channel to the receiver who decodes the message.
In the linear model, the sender encodes a message, sends it through a channel, and the receiver decodes the message. This model does not account for feedback or interaction between the sender and receiver, assuming that communication is a straightforward and direct transmission of information without any complexities or interruptions.
This model assumes that there is little to no feedback or interaction between the sender and receiver, and that the message is transmitted and received accurately without any distortion. However, this assumption is often criticized for oversimplifying the complex nature of communication and ignoring the role of context and feedback in the communication process.

3. Find the general solution of the following: a. 2dy/dx+y−y^3(x−1)=0
The general solution of the differential equation 2(dy/dx) + y - y^3(x - 1) = 0 is: y = ±√[1 - [(1/2) x + C]²]
To find the general solution of the differential equation:
2(dy/dx) + y - y³(x - 1) = 0
Let's rearrange the equation:
2(dy/dx) = y³(x - 1) - y
Divide both sides by 2:
dy/dx = (1/2)(y³(x - 1) - y)
let's separate the variables by bringing all y terms to one side and all x terms to the other side:
dy/[y³(x - 1) - y] = (1/2) dx
To integrate both sides, to perform a substitution. Let's substitute u = y²:
dy = (du/2√u)
Substituting back into the equation:
(du/2√u) / [u(x - 1) - √u] = (1/2) dx
Next, simplify the expression further:
du / [2√u(u(x - 1) - √u)] = (1/2) dx
Now, let's integrate both sides:
∫ du / [2√u(u(x - 1) - √u)] = ∫ (1/2) dx
This integral requires a trigonometric substitution. Let's substitute √u = sinθ:
du = 2sinθ cosθ dθ
Substituting back into the equation:
∫ (2sinθ cosθ dθ) / [2√(sinθ)²(sinθ(x - 1) - sinθ)] = (1/2) ∫ dx
Simplifying:
∫ sinθ dθ / √sinθ(sinθ(x - 1) - sinθ) = (1/2) ∫ dx
Now, integrate both sides:
∫ sinθ dθ = (1/2) ∫ dx
This gives us:
-cosθ = (1/2) x + C
Substituting back θ = arcsin(√u):
-cos(arcsin(√u)) = (1/2) x + C
Using the identity cos(arcsin(x)) = √(1 - x²):
-√(1 - (√u)²) = (1/2) x + C
Simplifying:
-√(1 - u) = (1/2) x + C
Substituting back u = y^2:
-√(1 - y^2) = (1/2) x + C
Finally, solving for y:
√(1 - y²) = -[(1/2) x + C]
Square both sides:
1 - y² = [(1/2) x + C]²
Rearranging the equation:
y² = 1 - [(1/2) x + C]²
Taking the square root:
y = ±√[1 - [(1/2) x + C]²]

ANSWER:
In geometry, a shape is defined as the figure closed by the limit. The boundary is created by combining lines, points, and curves. Basically, there are two different types of geometric shapes, such as:
• Two Dimensional shapes (2D):, Also known as flat shapes, are the shapes having two dimensions only. It has length and breadth. It does not have thickness.
,• Three Dimensional shapes (3D):, Also known as solid shapes, are the shapes that have three dimensions such as length, breadth and thickness.
Because of this, 2D figures are often associated with area and 3D figures with volume.
These are defined as follows:
\(\begin{gathered} A=s^2\rightarrow s=\sqrt{A} \\ \\ V=s^3\rightarrow s=\sqrt[3]{V} \end{gathered}\)This means that the length of the figure in 2D is equal to the square root of the area and also in 3D figures it is equal to the cube root of the volume.

Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Simplify your answer.) . A. The absolute maximum value off on Ris OB. There is no absolute maximum value. Determine the absolute minimum value off on R. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (Simplify your answer.) O A The absolute minimum value of fon Ris OB. There is no absolute minimum value.
The absolute maximum value of f on R does not exist, while the absolute minimum value of f on R is 6.
To find the absolute maximum and minimum values of f on R, we need to consider the critical points in the interior of R and the points on the boundary of R.
First, we find the critical points by taking the partial derivatives of f with respect to x and y, and setting them equal to 0:
fx = 6x - 6 = 0, fy = 7 = 0
Solving these equations gives us the critical point (1, 0).
Next, we find the values of f at the corners of R:
f(0, 1) = 10, f(0, -1) = 22, f(2, 1) = 6, f(2, -1) = 18
Finally, we check the values of f on the boundary of R by parametrizing the boundary curve as (t, 1-t^2) for 0 ≤ t ≤ 2. Evaluating f at these points gives us a minimum value of 6 at t = 2.
Since there is no maximum value of f on R, we conclude that the absolute maximum value does not exist. The absolute minimum value of f on R is 6.

Which is the best measure of center for second period and why? (5 points)
1. Mean, because there are no outliers that affect the center
2. Median, because there is 1 outlier that affects the center
3. Interquartile range, because there is 1 outlier that affects the center
4. Standard deviation, because there are no outliers that affect the center
Answer:
1. Mean, because there are no outliers that affect the center
Step-by-step explanation:
Second period: 3,2,3,1,3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2
Sorted values : 0, 1, 1, 1, 2, 2, 2, 2, 3, 3, 3, 3, 3, 4, 4
The mean = ΣX / n
n = sample size, n = 15
Mean = 34 / 15 = 2.666
The median = 1/2(n+1)th term.
1/2(16)th term = 8th term.
The 8th term = 2
The best measure of centre is the mean because the values for the second period has no outliers that might have affected the centre of the distribution.
Both interquartile range and standard deviation are measures of spread and not measures of centre.

What is the measure of side length x?The figure in the image is a right triangle with one of its interior angle at 90 degrees.
Angle A = 29 degree
Adjacent to angle A = X
Hypotenuse = 27 ft
To solve for the missing side length x, we use the trigonometric ratio.
Note that: cosine = adjacent / hypotenuse
Hence:
cos( A ) = adjacent / hypotenuse
Plug in the given values and solve for x.
cos( 29° ) = x / 27
Cross multiplying, we get:
x = cos( 29° ) × 27
