Answer: Linear
Step-by-step explanation:
Since the difference between consecutive values of f(x) is constant, this suggests that the function could be linear. To confirm this, we can calculate the differences between consecutive values:f(1) - f(0) = -15 - (-18) = 3
f(2) - f(1) = -12 - (-15) = 3
f(3) - f(2) = -9 - (-12) = 3
f(4) - f(3) = -6 - (-9) = 3
Since the differences are constant and equal to 3, this confirms that the function is linear.
To find the equation of the linear function, we can use the slope-intercept form of a linear equation:
y = mx + bwhere m is the slope and b is the y-intercept.
We can use the first two points (0, -18) and (1, -15) to find the slope:
m = (change in y) / (change in x) = (-15 - (-18)) / (1 - 0) = 3
Now we can use the slope and one of the points to find the y-intercept:
y = mx + b
-18 = 3(0) + b
b = -18
Therefore, the equation of the linear function is:
f(x) = 3x - 18
So the function type that could represent the values in the table is linear.

Find the critical numbers and absolute extrema for….
Final Answer: The critical number is x = DNE. The absolute maximum is x = 0.2, and y = -125.The absolute minimum does not exist on the interval.
To find the critical numbers?we need to find the values of x where the derivative of y equals zero or does not exist. So, we first find the derivative of y: y' = 10x^{(-3)}
The derivative is defined for all x in the interval [0.2, 2], so there are no points where the derivative does not exist.
To find where y' = 0, we set the derivative equal to zero and solve for x: [tex]10x^{(-3)} = 0[/tex] x = DNE There are no critical numbers since the derivative does not equal zero at any point in the interval.
Next, we check the endpoints of the interval: [tex]y(0.2) = -5/ (0.2^2) =[/tex] [tex]-125y(2) = -5/(2^2) = -1.25[/tex] Since y is a decreasing function on the interval,
the absolute maximum occurs at the left endpoint x=0.2: Absolute maximum: [tex]y(-0.2) = -125[/tex]
Since y is an unbounded function as x approaches zero, there is no absolute minimum on the interval [0.2, 2].
Final Answer: The critical number is x = DNE.The absolute maximum is x = 0.2, and y = -125.The absolute minimum does not exist on the interval.

Help with this trig identities problems.
1) Given csc Φ = 7/3 and cot Φ = - (2√10)/(3), find sec Φ.
2) Given that sec β = 6/5 and sin β > 0, find tan β and sin β.
Using trigonometric identities, we found that sec Φ = -7/(2√10), sin Φ = 3/7, tan β = √11/5, and sin β = √11/6 for the given values of csc Φ, cot Φ, and sec β.
1. We can start by using the Pythagorean identity to find the values of sin Φ:
[tex]sin^2[/tex] Φ + [tex]cos^2[/tex] Φ = 1
Since csc Φ = 1/sin Φ, we can substitute and solve for sin Φ:
1/(7/3) = sin Φ
sin Φ = 3/7
Next, we can use the fact that cot Φ = cos Φ/sin Φ:
cot Φ = cos Φ/(3/7) = - (2√10)/(3)
Simplifying this expression, we get:
cos Φ = - (2√10)/(3) * (3/7) = - 2√10/7
Finally, we can use the fact that sec Φ = 1/cos Φ:
sec Φ = 1/(- 2√10/7) = -7/(2√10)
2. We can use the fact that sec β = 1/cos β to find the value of cos β:
sec β = 6/5
cos β = 5/6
Next, we can use the Pythagorean identity to find the value of sin β:
[tex]sin^2[/tex] β + [tex]cos^2[/tex] β = 1
sin β = √(1 - [tex]cos^2[/tex] β) = √(1 - 25/36) = √(11/36) = √11/6
Finally, we can use the fact that tan β = sin β/cos β:

The table that represents the function for a lawn being mowed more quickly than by Killian's rate is given as follows:
Second table.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
Killian can cut grass at a rate of 1000 square feet each 10 minutes, hence his average rate of change is given as follows:
1000/10 = 100 square feet per minute.
For the second table, in 7 minutes, 1100 square feet of lawn is mowed, hence the rate is given as follows:
1100/7 = 157 square feet per minute.
It is more quickly than Killian's as the rate of change is greater.

Find the Volume of the triangular prism
For the given triangular prism, the volume value is obtained as Option B: 31.5 in³.
What is a triangular prism?
The pentahedron Triangular Prism contains nine different nets. The bases' vertices and edges are connected by means of their three rectangular sides. The rectangular sides of the triangular prism are joined to one another side by side. Every cross-section that is perpendicular to the base faces is a triangle.
The height of the triangular prism is given as 2 inches.
The base of the triangular prism is given as 7 inches.
The length of the triangular prism is given as 4.5 inches.
The volume of a triangular prism is given by the formula -
V = (1/2) × b × h × l
where b is the base of the triangle, h is the height of the triangle, and l is the length of the prism.
Substituting these values into the equation, we get -
V = (1/2) × 7 inches × 2 inches × 4.5 inches
V = 7 inches × 1 inch × 4.5 inches
V = 31.5 cubic inches
Therefore, the volume of the triangular prism is 31.5 cubic inches.

What is the scale factor?
The scaling factor for given transformation is 3.
What exactly is scaling factor?
The scaling factor, also known as the scale factor, is a value that indicates how much a geometric figure is enlarged or reduced. It is the ratio of the length of a side or dimension of the original figure to the length of the corresponding side or dimension of the new figure. The scaling factor can be greater than 1, which indicates an enlargement, or less than 1, which indicates a reduction. When the scaling factor is 1, the two figures are congruent, which means they have the same shape and size.
Now,
We can find the scale factor by comparing the corresponding side lengths of the two polygons. Let's start by finding the side lengths of the original polygon:
HI: √[(4-0)² + (-5+3)²] = √20
IJ: √[(6-4)² + (0-0)²] = 2
JK: √[(4-6)² + (5-0)²] = √41
KL: √[(0-4)² + (3-5)²] = √20
LH: √[(0-0)² + (-3+5)²] = 2
Now let's find the corresponding side lengths of the dilated polygon:
H'I': √[(12-0)² + (-15+9)²] = √600
I'J': √[(18-12)² + (0-0)²] = 6
J'K': √[(12-18)² + (15-0)²] = √600
K'L': √[(0-12)² + (9-0)²] = √600
L'H': √[(0-0)² + (-9+3)²] = 6
We can see that the side lengths of the dilated polygon are all 3 times as long as the corresponding side lengths of the original polygon. Therefore, the scale factor is 3.

Because the x2 term's coefficient is positive, the function will rise without equation bound as x approaches infinity or negative infinity. As a result, no horizontal asymptote exists.
What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9".
The y-intercept of the equation y = (0,0) is the point on the line where it meets the y-axis and corresponds to the value of y when x equals 0. As a result, the equation y = 0's y-intercept is (0,0).
An equation's domain is the set of all possible values of x for which the equation is defined.
a) Because there are no constraints on the potential values of x, the domain of the equation y = x2 - 4x is all real integers.
b) The domain of the equation y = 1/(x-4) includes all real numbers except x = 4, which is undefined since division by zero is undefined.
c) Because the term within the square root must be non-negative, the domain of the equation y = sqrt(x-3)(x-4) is x >= 3.
As x approaches a specific value, the graph of the function approaches but never reaches vertical asymptotes. As the denominator of a rational function hits 0, they arise.
Because y = (x-3)(x-4) is not a rational function, it lacks vertical asymptotes.
A function's horizontal asymptote is a horizontal line that it approaches when x approaches infinity or negative infinity.
The dominant term in the formula as x gets extremely large or very tiny is x2, thus we can rewrite the equation as [tex]y = x2 - 7x + 12[/tex] .
Therefore, Because the x2 term's coefficient is positive, the function will rise without bound as x approaches infinity or negative infinity. As a result, no horizontal asymptote exists.

A volleyball team wants to order a team T-shirt. The Red Nose company charges $3.50 per shirt plus a $79 flat fee. The green Machine company charges $5 per shirt plus a $40 flat fee. Let T be the total cost and R be the number of shirts
show your full work
Red Nose: t = 4.50r + 55
Green Machine: t = 5r + 40
Find the total number of shirts that would make the total cost for each company the same
Number of shirts:
Cost:
Answer:
To find the total number of shirts that would make the total cost for each company the same, we can set the two equations equal to each other and solve for the number of shirts:
Red Nose: t = 3.50r + 79
Green Machine: t = 5r + 40
3.50r + 79 = 5r + 40
Subtracting 3.50r from both sides, we get:
79 = 1.50r + 40
Subtracting 40 from both sides, we get:
39 = 1.50r
Dividing both sides by 1.50, we get:
r = 26
So the total cost for each company would be the same if 26 shirts are ordered.
To find the total cost for each company when 26 shirts are ordered, we can substitute 26 for r in each equation:
Red Nose: t = 3.50(26) + 79 = $192
Green Machine: t = 5(26) + 40 = $170
Therefore, if 26 shirts are ordered, the total cost would be $192 for Red Nose and $170 for Green Machine.
If $14,000 is invested at 7% annual interest, which is compounded continuously, what is the account balance after 12 years, assuming no additional deposits or withdrawals are made?
the account balance after 12 years of continuous compounding at 7% annual interest, assuming no additional deposits or withdrawals are made, would be $32,447.44.
The formula for continuous compounding is:
A = P[tex]e^(rt)[/tex]
where:
A = the final amount
P = the principal amount (initial investment)
e = the mathematical constant approximately equal to 2.71828
r = the annual interest rate
t = the time in years
Plugging in the given values, we get:
A = 14000[tex]e^(0.0712)[/tex]
A = 14000*[tex]e^0.84[/tex]
A = 14000*2.31796
A = $32,447.44

C - Vertex constant(h, k) - Vertex coordinates.Now we proceed to determine the vertex form of each quadratic equation:
Case 9
y = 2 · x² + 4 · x - 4
y = 2 · (x² + 2 · x - 2)
y = 2 · (x² + 2 · x + 4) - 12
y = 2 · (x + 2)² - 12
Case 10
y = - (1 / 2) · x² - 3 · x + 3
y = - (1 / 2) · [x² + (3 / 2) · x - 3 / 2]
y = - (1 / 2) · [x² + (3 / 2) · x + 9 / 16] + (1 / 2) · (33 / 16)
y = - (1 / 2) · (x + 3 / 4)² + 33 / 32
Case 11
y = 3 · x² - 8 · x
y = 3 · [x² - (8 / 3) · x]
y = 3 · [x² - (8 / 3) · x + 16 / 9] - 3 · (16 / 9)
y = 3 · (x - 4 / 3)² - 16 / 3
Case 12
y = - 3 · x² + 18 · x - 27
y = - 3 · (x² - 6 · x + 9)
y = - 3 · (x - 3)²
Case 13
y = x² - 8 · x + 19
y = (x² - 8 · x + 16) + 3
y = (x - 4)² + 3
Case 14
y = x² - 2 · x - 6
y = (x² - 2 · x + 1) - 7
y = (x - 1)² - 7
Case 15
y = x² + 3 · x
y = (x² + 3 · x + 9 / 4) - 9 / 4
y = (x + 3 / 2)² - 9 / 4
Case 16
y = 2 · x² + x
y = 2 · [x² + (1 / 2) · x]
y = 2 · [x² + (1 / 2) · x + 1 / 16] - 2 · (1 / 16)
y = 2 · (x + 1 / 4)² - 1 / 8
Case 17
y = 2 · x² - 12 · x + 11
y = 2 · (x² - 6 · x + 9) - 2 · (7 / 2)
y = 2 · (x - 3)² - 7
Case 18
y = - 2 · x² - 4 · x + 8
y = - 2 · (x² + 2 · x - 4)
y = - 2 · (x² + 2 · x + 1) + 2 · 5
y = - 2 · (x + 1)² + 10

You mix gas and oil to obtain 2 and 1/2 gallons of mixture for an engine. The mixture is 40 parts gasoline and 1 part oil. How much gasoline must be added bring the mixture to 50 parts gasoline and 1 part oil?
We need to add a volume of 39.69 fluid ounces of gasoline to the mixture to bring it to 50 parts gasoline and 1 part oil.
What is mensuration?Mensuration is the branch of mathematics concerned with the measurement of geometric figures and parameters such as length, volume, shape, surface area, and lateral area.
According to information in the question:
The mixture is 40 parts gasoline and 1 part oil, there are 40 + 1 = 41 parts in total.
Let, the amount of oil in the mixture "x".
We know that there are 2 and 1/2 gallons of the mixture, which is the same as 2.5 * 128 = 320 fluid ounces.
So, the equation which can be formed is
x/41 * 320 = the amount of oil in the mixture (in fluid ounces)
Solving for "x":
x/41 * 320 = x/41 * 50 + 320 - (x/41 * 50)
Multiplying both sides by 41:
x * 320 = 50x + 41(320 - 50x)
Simplifying:
320x = 41(320)
x = 41 * 10 = 410 (fluid ounces of oil in the mixture)
Thus, amount of gasoline in the mixture is
40 parts gasoline / 41 parts total * 320 fluid ounces = 311.22 fluid ounces of gasoline.
Let the gasoline we need be "y", so a equation can be formed as follows
(311.22 + y)/(41 + y) * 320 = 410
Solving for y:
(311.22 + y)/(41 + y) = 410/320
Multiplying both sides by (41 + y) * 320:
311.22 + y = 410/320 * (41 + y) * 320
Simplifying:
311.22 + y = 205.625 * (41 + y)
311.22 + y = 8434.375 + 205.625y
Solving for y:
204.625y = 8123.155
y = 39.69 (fluid ounces of gasoline to add)
Therefore, we need to add 39.69 fluid ounces volume of gasoline to the mixture to bring it to 50 parts gasoline and 1 part oil.

CRITICAL THINKING Consider AJKL.
Rotate AJKL 90° clockwise about the origin.
How are the x- and y-coordinates of AJ'K'L'
related to the x- and y-coordinates of AJKL?
a.
The x- and y-coordinates of AJ'K'L' are related to the x- and y-coordinates of AJKL, as x-coordinate of AJ'K'L' = -y-coordinate of AJKL and y-coordinate of AJ'K'L' = x-coordinate of AJKL.
Explain coordinate plane?We create the x-axis and y-axis in the coordinate plane. the origin, where the x- and y-axes cross, and the coordinates ( 0,0 ). The horizontal axis represents the x-axis. The vertical axis represents the y-axis. The first and second coordinates are for the horizontal and vertical axes, respectively. On the coordinate plane, coordinates are expressed by ( x ,y ). The x-coordinate stands for the first coordinate.
When a point is rotated 90° clockwise about the origin, its x-coordinate becomes the negative of its original y-coordinate, and its y-coordinate becomes the positive of its original x-coordinate.
So, for point A(x,y), its new coordinates after a 90° clockwise rotation about the origin would be A'(-y,x). Similarly, for point J, K, and L, their new coordinates would be J'(-yj,xj), K'(-yk,xk), and L'(-yl,xl) respectively.
Therefore, the x- and y-coordinates of AJ'K'L' are related to the x- and y-coordinates of AJKL as follows:
x-coordinate of AJ'K'L' = -y-coordinate of AJKL
y-coordinate of AJ'K'L' = x-coordinate of AJKL

In circle C with the measure of minor arc BD=42°, find mBED.
Answer: mBED = 2(42°) = 84°
Step-by-step explanation:
We are asked to find the measure of the central angle ∠BED in the circle given that the measure of the minor arc BD is 42°.
We can use the formula that states that the measure of a central angle is equal to twice the measure of its intercepted arc. That is,
m∠BED = 2*mBD
We can substitute the value of mBD, which is 42°, into our equation.
m∠BED = 2*42°
m∠BED = 84°
Therefore, the measure of the central angle ∠BED is 84°.
What values of y and z make
The value of y and z are 11 and 11.
How to determine the valuesWe can see from the diagram that the two triangles are of equal lengths.
To determine the value of the variables, we have to note that;
In triangle QRS, the adjacent sides is y + 20
In triangle VX, the adjacent side is y = 31
Now, equate the values
y + 20 = 31
collect like terms
y = 31 -20
y = 11
Also, the hypotenuse sides are equivalent, then
y + 3z + 28 = 6y + z - 5
collect the like terms
y - 6y + 3z - z = -5 - 28
add or subtract the values
-5y + 2z = -33
Substitute the values
2z = -33 + 55
2z = 22
z = 11
