According to the given function,

Domain = [tex]\left(-\infty, -4\right) \cup \left(-4, 2\right) \cup \left(2, \infty\right)[/tex]

Vertical Asymptote = 4

Horizontal Asymptote = 0

X - intercept = No x - intercepts

Y - intercept = 1/4

Domain:

The  the domain of a function referred as the set of inputs accepted by the function

Given,

The function is,

[tex]f(x)=\frac{x-2}{x^2+2x-8}[/tex]

Here we need to find the domain, vertical asymptote, horizontal asymptote,  x - intercept, and y-intercept.

To find the domain and intercepts, we have to plot the graph for the given function.

So, the graph of the function is attached below. It can be drawn using the graphing calculator.

As per the graph,

Domain = [tex]\left(-\infty, -4\right) \cup \left(-4, 2\right) \cup \left(2, \infty\right)[/tex]

And the values of

x - intercept = No x-intercepts

y - intercept = 1/4

Now, the vertical asymptote is calculated as,

The line x=L is a vertical asymptote of the function f(x), if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.

x = -4

Then,

[tex]\lim_{x \to -4^+} \frac{1}{x + 4}=\infty[/tex]

Since the limit is infinite, then x=−4 is a vertical asymptote.

And the horizontal asymptote is,

Line y=L is a horizontal asymptote of the function y=f(x), if either '

[tex]\lim_{x \to \infty} f{\left(x \right)}=L[/tex] or [tex]\lim_{x \to -\infty} f{\left(x \right)}=L[/tex]  and L is finite.

When we calculate the limits:

[tex]\lim_{x \to \infty}\left(\frac{x - 2}{x^{2} + 2 x - 8}\right)=0\\\\\lim_{x \to -\infty}\left(\frac{x - 2}{x^{2} + 2 x - 8}\right)=0[/tex]

Thus, the horizontal asymptote is y=0.

The first step we need to do is to convert the measures from inches to feet (12 inches is 1 foot):

8 inches = 8/12 feet = 0.667 feet

6 inches = 6/12 feet = 0.5 feet

So the measures are 12.667 ft and 14.5 ft.

Now, to find the area of the rectangular living room, we just need to multiply these measures:

Since we expect a waste of 10%, we need to increase this area by 10%, that is, we multiply it by 110% or 1.1:

Step-by-step explanation:

a distance on a coordinate grid is always the Hypotenuse of a right-angled triangle with the differences of the x coordinates and the y coordinates as the legs.

so, per Pythagoras

distance² = (x diff)² + (y diff)²

we have here a distance 17. 17² = 289.

to get integer coordinates the lengths of the legs must be integer numbers.

what 2 squared integer numbers can be added to get 289 ?

I found after subtracting 4, 9, 16, 25, 36, 49 and finally 64 (the squares of 2, 3, 4, 5, 6, 7, 8) that

289 - 64 = 225, which is also a square number (15²).

so, we get the possible integer coordinates of Q to be

(-4 + 8, 7 + 15) = (4, 22)

in this case the shorter leg has the length 8, and the longer leg the length 15.

the shorter leg is in this case horizontal, because it is the x coordinate difference. and Q is again as described (4, 22).

if we make the shorter leg vertical, that means it is the y coordinate difference. and Q is then

(-4 + 15, 7 + 8) = (11, 15)

The  graphed piecewise function is conformed of two lines, it can be written as::

Notice that we have two lines that conform the piecewise function.

The linear equation in the left passes through the points (-8, 8) and (-1, 1), so the slope is:

m = (1 - 8)/(-1 + 8) = -7/7 = -1

Then it is something like:

y = -x + b

To find the value of b we use the point (-1, 1), we will get:

1 = -(-1) + b

1 - 1 = b

0 = b

Then the first line is:

y = -x   if x < -1.

The second line passes through points (-1, -3) and (4, 2), then the slope is:

m = (2 + 3)/(4 + 1) = 1

And we can see that it intercepts the y-axis at y = -1, so the linear equation here is:

y = x - 1

Answer:

x = a/2 + 9/2

Step-by-step explanation:

Solve for x:

x^2 - 18 x + 81 = (x - a)^2

Expand out terms of the right hand side:

x^2 - 18 x + 81 = x^2 - 2 a x + a^2

Subtract x^2 - 2 a x + a^2 from both sides:

2 a x - 18 x - a^2 + 81 = 0

Collect in terms of x:

81 - a^2 + x (2 a - 18) = 0

Factor constant terms from the left hand side:

-(a - 9) (-2 x + a + 9) = 0

Divide both sides by -a + 9:

-2 x + a + 9 = 0

Subtract a + 9 from both sides:

-2 x = -a - 9

Divide both sides by -2:

Answer: x = a/2 + 9/2

Based on the fact that the data for the average CO₂ over the whole year was smoother than the daily and monthly level, the term for the phenomenon is called Smoothing.

Smoothing refers to a process in statistics where the messier points of a data distribution is removed. In other words, the data points that give the data set a varied distribution are removed so that the data set appears smoother.

There are several methods to engage in smoothing but most of them use averaging over a longer period of time. They would for instance, use the averages of a period over a month or weekly and convert it to an annual measure like the scatterplot of CO₂ for the year.

In conclusion, the fact that the average CO₂ scatterplot for the year was smoothly than monthly or daily is due to smoothing.

ANSWER

The graph of y = sin θ shifted to the left by π/2 units

EXPLANATION

This is the graph of y = sin θ shifted to the left π units. In function notation, this shift is represented by adding π to the variable: y = sin (θ + π).

Also, we know that the graph of y = cos θ is like the graph of y = sin θ but shifted π/2 units to the left. So, if we shift the graph of y = cos θ π/2 units to the left, we get the given graph.

Therefore, the only description that does not match the graph is the graph of y = sin θ shifted to the left by π/2 units.

========================================================

Explanation:

The angles 72 and x form a 180 degree straight line.

72+x = 180

x = 180-72

x = 108

Angles x and 5y-3 are congruent corresponding angles assuming the lines pointing to the northwest are parallel

5y - 3 = x

5y - 3 = 108

5y = 108+3

5y = 111

y = 111/5

y = 22.2

Answer:

x = 108°

y = 22.2°

Angles on a straight line sum to 180°.

[tex]\implies 72^{\circ} + x = 180^{\circ}[/tex]

[tex]\implies 72^{\circ} + x - 72^{\circ} = 180^{\circ} - 72^{\circ}[/tex]

Assuming the two lines that appear parallel in the given diagram are parallel:

[tex]\implies (5y - 3)^{\circ} = x^{\circ}[/tex]

[tex]\implies 5y - 3 = 108[/tex]
