Explanation:
The domain is the set of allowed x inputs.
The left-most part of the graph is at x = -9. There is no right-most part since it goes on forever in that direction due to the arrow.
So we can say [tex]x \ge -9[/tex] or [tex]-9 \le x[/tex] or [tex]-9 \le x < \infty[/tex]
That third inequality mentioned then turns into the interval notation [tex]\big[-9, \infty\big)[/tex]
Use a square bracket to include -9 as part of the domain. It's included because of the closed filled in circle, in contrast to a open hole.
We always will use a curved parenthesis for either infinity since we cannot actually reach it (it's not a number to reach).
---------------------
Now onto the range. This is the set of possible y outputs.
The graph stretches forever downward, so there is no lower bound. The upper bound, or highest part, is when y = 3
The range as a compound inequality is [tex]-\infty < y \le 3[/tex] which condenses to the interval notation of [tex]\big( -\infty , 3 \big][/tex]
Once again, use a square bracket to include the endpoint 3.
----------------------
The absolute max is the highest point of the graph. It's the peak of the mountain. In this case, the absolute max is y = 3. This is the relative max also. The relative max is the maximum within a certain specified interval.
There is no absolute min since the graph goes downward forever. There is no lowest point. This also rules out a relative min as well.
----------------------
The function is increasing when it goes uphill as you move to the right.
The graph shows the function increases on the interval -9 < x < -3 which condenses to the interval notation (-9, -3). This is NOT ordered pair notation which unfortunately looks identical to interval notation when using curved parenthesis for both endpoints.
In contrast, the function decreases when it goes downhill (when moving to the right). This occurs when [tex]4 < x < \infty[/tex] which shortens down to the interval notation of [tex](4, \infty)[/tex]
The graph is flat or constant when it's neither increasing nor decreasing. The graph is constant when -3 < x < 4 which translates to the interval notation of (-3, 4)
----------------------
Now onto the x and y intercepts
The x intercepts are where the graph crosses the horizontal x axis.
We have the two locations of x = -6 and x = 6 as the x intercepts
The y intercept is at y = 3, which is where it crosses the y axis. This also happens to be the max value mentioned earlier, though the y intercept won't always be the max.
-----------------------
Lastly, let's compute f(8)
Locate 8 on the x axis. Then draw a vertical line through this. The vertical line crosses the curve at (8, -3). Then move to the left until hitting y = -3 on the y axis
So x = 8 plugged in leads to y = -3 as the output.
Therefore, f(8) = -3

Applying the triangle sum theorem, the value of x is: 4.
How to Apply the Triangle Sum Theorem?When we add the three interior angles of a triangle together, the sum must be equal to 180 degrees according to the triangle sum theorem.
Given the triangle with the following interior angles, 35°, (22x - 3)°, and 60°. Therefore:
35 + (22x - 3) + 60 = 180 [triangle sum theorem]
Solve for x
35 + 22x - 3 + 60 = 180
Combine like terms
92 + 22x = 180
Subtract 92 from each side of the equation
92 + 22x - 92 = 180 - 92
22x = 88
Divide both sides by 22
22x/22 = 88/22
x = 4
Thus, applying the triangle sum theorem, the value of x is: 4.

find the point (x y) on the unit circle that corresponds to the real number t. t = π/6
Answer:
The value of x is -√3/2 and the value of y = -1/2.
Step-by-step explanation:
It is given that t = π/6 and we need to find the point (x y) on the unit circle that corresponds to the real number t.
Now,
Let us suppose that the real number 't' is to be of an arc length from the positive X-axis.
=> t = π/6
Further, if we look at the graph given below;
We observe that the reference angle π/6 is one of the standard angles with the ratio of opposite to adjacent sides as indicated above.
=> x, y = -√3/2, -1/2
Therefore, it can be inferred from the graph that the value of x is -√3/2 and the value of y = -1/2.

Since there are 5 more 2-bedroom apartments than 1- bedroom apartments. This will be b+5.
There are 15 apartments. Therefore, the expression will be:.
b + b + 5 = 15
2b + 5 = 15.
2b = 15 - 5.
2b = 10
b = 10 / 2

Use sigma notation to represent the sum of a geometric series with a first term of 3 and a common ratio of 10/9
The sum of a geometric series with a first term of 3 and a common ratio of 10/9 is;
∑ [tex]3 (\frac{10}{9} )^k^-^1[/tex] where, K = 1 to n.
What is Geometric series?
A geometric series is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.
Given that;
The first term is 3 and the common ratio is 10/9.
Now, A geometric sequence has the form:
a, ar , ar², ar³, . . .
Hence, The nth term of a geometric sequence is;
⇒ ∑ [tex](ar^k^-^1)[/tex] where, k = 1 to n.
Therefore, the sum of geometric series with a first term of 3 and a common ratio of 10/9 is:

First we can find out the place value,
Then we can write,
Define Place value :
Place value is the basis of our entire number system. This is the system in which the position of a digit in a number determines its value. The number 42,316 is different from 61,432 because the digits are in different positions.
[or]
Place value of a digit can be defined as the position of the particular digit in a given number.
For Example :
The place value of 7 in 1870 is 70
Given the data,
First we use digit is : 184.36
Second we use digit is : 9027.83
Place value of 8 in First digit is ⇒ 184.36 is 80
Place value of 8 in Second digit is ⇒ 9027.83 is 0. 8
We can solve the Ratio is :
Ratio = 80/ 0.8

Step-by-step explanation:
Simplify the quadratic equation.
[tex]3x^2-18x+5 = 473x^2-18x+5-47 = 0\\3x^2-18x-42 = 0\\\\a = 3\\b = -18\\c = -42\\\\x = (-(-18)\pm\sqrt{ (-18)^2-4(3)(-42) )} \div 2(3)\\x = (18\pm\sqrt{ 324+504)} \div 6\\x = (18\pm\sqrt{ 828}) \div 6[/tex]
Simplify further.
[tex]x = (18\pm\sqrt{ 23\times 36}) \div 6\\x = (18\pm6\sqrt{ 23}) \div 6\\x = 6(3\pm\sqrt{23}) \div 6[/tex]

What is a Quadratic equation?ax²+bx+c=0, with a not equals to 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
To solve for x in the equation 3x^2 - 18x + 5 = 47, we can begin by simplifying the equation:
[tex]3x^2 - 18x - 42 = 0[/tex]
Next, we can divide both sides of the equation by 3 to get:
[tex]x^2 - 6x - 14 = 0[/tex]
To solve for x, we can use the quadratic formula:
[tex]x =\frac{ (-b \pm \sqrt{(b^2 - 4ac))} }{ 2a}[/tex]
In this case, a = 1, b = -6, and c = -14, so we have:
[tex]x = \frac{(-(-6) \pm \sqrt{((-6)^2 - 4(1)(-14)))}}{2(1)} \\x = \frac{(6 \pm \sqrt{(36 + 56))}}{ 2} \\x = (6 \pm \sqrt{92}) / 2[/tex]
Simplifying the radical, we get:
x = (6 ± 2√23) / 2
Dividing both the numerator and denominator by 2, we get:
x = 3 ± √23
Therefore, the two solutions to the equation [tex]3x^2 - 18x + 5 = 47[/tex] are x = 3 + √23 and x = 3 - √23.

What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
Triangle ABC is dilated with a scale factor of 3. Then the scale factor will be 3.
If the side BC is 5.4 units long, then the length of the side B'C' will be
B'C' = 3 x BC
B'C' = 3 x 5.4
B'C' = 16.2 units
If the side A'B' is 8.2 units long, then the length of the side AB will be
AB = A'B' / 3
AB = 8.2 / 3
AB = 2.7 units
If the measure of the angles ∠A, ∠B, and ∠C are 77.5°, 54.2°, and 48.3°, respectively.
There is no effect of dilation on the angle. Then the angles will remain the same.
The length of the sides AB and B'C' will be 2.7 units and 16.2 units, and the measure of the angles ∠A, ∠B, and ∠C are 77.5°, 54.2°, and 48.3°, respectively.

What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now given that,
Total farms of land = 576 acres
Part of land planted soyabeans = 3/16 of total farms of land
Putting the values we get,
Part of land planted soyabeans = 3/16 of 576 acres
Simplifying we get,
Part of land planted soyabeans = 3/16 * 576 acres
Solving we get,
Part of land planted soyabeans = 1,728/16 acres
