14. Find a counterexample for each of the following: a. If n is a natural number, then(n+5)/5 -n-1. b. If n is a natural number, then (n + 4)² = n² + 4².
n = 1 is a counterexample for both the given equations.
Here, we are given two equations, let us look at them one by one-
a. (n + 5) / 5 = n + 1
let us take n = 1
the, (1 + 5) / 5 = 1 + 1
6/ 5 = 2
This equation does not hold as 6/5 ≠ 2. Thus, n = 1 doesn't satisfy the given equation and hence is a counterexample.
b. (n + 4)² = n² + 4²
Let us take n = 1
(1 + 4)² = 1² + 4²
5² = 1 + 16
25 = 17
Again, this equation does not hold as 25 ≠ 17. Thus, n = 1 doesn't satisfy the given equation and hence is a counterexample.

f(x) = -x + 7
g(x) = x² - 4x + 4
Find: (gof)(x)
Answer:
[tex](g \circ f)(x) = x^2-10x+25[/tex]
Step-by-step explanation:
Given:
[tex]\begin{cases}f(x)=-x+7\\g(x)=x^2-4x+4 \end{cases}[/tex]
Function composition is an operation that takes two functions and produces a third function.
The composite function (g o f)(x) means to substitute the function f(x) in place of the x in function g(x).
[tex]\begin{aligned} \implies (g \circ f)(x) & = g\left[f(x)\right]\\& = g(-x+7)\\& = (-x+7)^2-4(-x+7)+4\\& = (-x+7)(-x+7)+4x-28+4\\& = x^2-14x+49+4x-28+4\\& = x^2-14x+4x+49-28+4\\& = x^2-10x+25\end{aligned}[/tex]

Answer:
x² - 10x + 25
Step-by-step explanation:
The given information is,
→ f(x) = -x + 7
→ g(x) = x² - 4x + 4
The equation we form is,
→ (gof)(x)
→ g[f(x)]
→ f(x)² - 4f(x) + 4
Let's solve the problem,
→ f(x)² - 4f(x) + 4
→ (-x + 7)² - 4(-x + 7) + 4
→ x² - 14x + 49 + 4x - 28 + 4
→ x² - 10x + 25
Hence, answer is x² - 10x + 25.

point A bisects LS BC. If LS BA=6x-3 and LS AC= 3x+7. Solve for X. PLS ANSWER QUICKLY!!!
Based on the bisection of line BC by point A, the value of x is 10/3
How to determine the value of x?The given parameters are:
Point A bisects BCBA = 6x - 3 AC= 3x + 7Because the point A bisects BC, then
BA = AC
Substitute the known values in the above equation
So, we have
6x - 3 = 3x + 7
Collect the like terms
6x - 3x = 3 + 7
Evaluate the like terms
3x = 10
Divide both sides of the equation by 3
x = 10/3
Hence, based on the bisection of line BC by point A, the value of x is 10/3

Use the figure below to list the slopes m₁, m₂, m3, and m4 in order of decreasing size.
In decreasing size, the slopes of the linear functions are given as follows:
m4, m3, m2, m1.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Regarding the slope, we have that:
Increasing lines have positive slopes.Decreasing lines have negative slopes.Hence, for the lines in this graph:
m4 and m3 are positive.m2 and m1 are negative.Then, we consider the intensity of growth/decay.
The pink line increases faster than the green line, meaning that it has a greater slope, that is, m4 > m3.The red line falls faster than the blue line, meaning that it's slope has a greater absolute value, but is less than m2, as they are negative, hence m2 > m1.Thus the list is given by:
m4, m3, m2, m1.

f has a range of (-infinaty, 7),
and a graph that is symmetric
about the line x = 3, and has a
Y-intercept of 4
Answer:
[tex]f(x)=-|x-3|+7[/tex]
Step-by-step explanation:
The parent function of an absolute function is the modulus function:
[tex]f(x)=|x|[/tex]
Graph of Modulus function:
(see 2nd attachment)
[tex]f(x)=|x|=\begin{cases} \textsf{\:\:\:$x$, \quad if $x\geq 0$}\\\textsf{$-x$, \quad if $ x < 0$} \end{cases}[/tex]
Its vertex is at the origin (0, 0).
Its line of symmetry is x = 0.
It opens upwards.
Given information:
Range: (-∞, 7)Axis of symmetry: x = 3y-intercept: (0, 4)The axis of symmetry is the x-value of the vertex of an absolute function.
The y-value of the range is the y-value of the vertex of an absolute function.
Therefore, the vertex of the absolute function f(x) is (3, 7).
Graphing
Plot the vertex at (3, 7) and the y-intercept at (0, 4).As the function f(x) has a range of (-∞, 7), it opens downwards. Draw a straight line through the y-intercept that terminates at the vertex.Draw a line that is symmetrical to this line.To find the equation of the absolute function, work out the series of transformations that take the parent function to the given function.
As the function f(x) has a range of (-∞, 7), it opens downwards. Therefore, the parent function has been reflected in the x-axis:
[tex]\implies -f(x)=-|x|[/tex]
As the function f(x) is symmetric about the line x=3, the parent function has been translated 3 units to the right:
[tex]\implies -f(x-3)=-|x-3|[/tex]
Finally, as the highest y-value of the function is y = 7, the y-value of its vertex is y = 7. Therefore, the parent function has been translated 7 units up:
[tex]\implies -f(x-3)+7=-|x-3|+7[/tex]
Therefore, the equation of the absolute function with the given parameters is:
[tex]f(x)=-|x-3|+7[/tex]

Omar runs 0.9577 miles each morning .
Circumference of circle or perimeter of the circle is that the measure of the boundary of the circle whereas the world of circle defines the region occupied by it which is given by A = πr² where "r" is the radius of the circle.If we tend to open a circle and create a line out of it, then its length is that the circumference which is given by C = 2πr where "r" is the radius of the circle.It's typically measured in units, like cm or unit m.It is given that area of the circular park is .02 square miles .
Using area formula , we get
0.02 = πr²

The elevation of a sunken ship is $-120$ feet. You are in a submarine at
an elevation that is $\frac{5}{8}$
of the ship’s elevation. What is your elevation?
The supplied statement indicates that the angle of elevation will be = -75 feet.
What is angle of elevation?The term angle of elevation refers to the angle between the horizontal and an object. The line of sight of an observer would be over the horizontal. The term angle of depression refers to the angle between the horizontal and an item. The line of sight of an observer would fall below the horizontal.
In arithmetic, how do you find elevation?"rise over run" is an easy-to-remember equation for calculating a change in elevation as a decimal, which means the rise (the change in vertical distance) divided by that of the run (the change in horizontal distance). As an example, suppose the increase is two and the run is six. So you'd multiply 2 by 6 (or 2/6) to get.
According to the given information:Given The elevation of a sunken ship = 120 feet
the elevation of a submarine = 5/8
So,
Your elevation will be given by employing the MULTIPLICATION OPERATION.
(5/8) x -120 feet
