The range of the function f(x) is all real numbers except for -6.
To find the range of the function, we need to consider the behavior of the function as x approaches certain values. The denominator of the function is x + 4.5, which means the function is undefined when x = -4.5, as division by zero is not defined.
When x approaches -4.5 from the left side (x < -4.5), the function values become increasingly negative. Similarly, when x approaches -4.5 from the right side (x > -4.5), the function values become increasingly positive.
Since the function is undefined at x = -4.5, we exclude that value from the range. Therefore, the range of the function f(x) is all real numbers except for -6. In interval notation, the range can be expressed as (-∞, -6) ∪ (-6, ∞).

Given circle B.If measure of arc AD = 118 degrees, find the measure of angle DBC.
The measure of angle DBC is half the measure of its intercepted arc AD. Therefore, if arc AD measures 118 degrees, angle DBC measures 59 degrees.
To find the measure of angle DBC, we need to use the properties of angles formed by intersecting chords and arcs in a circle.
In this case, we are given that the measure of arc AD is 118 degrees. By the Inscribed Angle Theorem, the measure of angle DBC is equal to half the measure of its intercepted arc, which is arc AD.
Therefore, the measure of angle DBC is 118 degrees divided by 2, which is 59 degrees.
Thus, the measure of angle DBC is 59 degrees.

B
y = −x − 1
C
y = x + 1
D
y = x − 1
The equation that best models the data in the scatter plot is option D: y = x - 1.
In the given scatter plot, the data points appear to form a straight line that slopes upwards from left to right. The equation y = x - 1 represents a linear function with a slope of 1 and a y-intercept of -1. This means that for every unit increase in x, y increases by the same amount (1), and when x is 0, y is -1.
Option A, y = -x + 1, has a negative slope and would result in a line that slopes downwards from left to right, which does not match the data in the scatter plot.
Option B, y = -x - 1, also has a negative slope and a different y-intercept, which does not align with the data in the scatter plot.
Option C, y = x + 1, has a positive slope but a different y-intercept, which does not accurately represent the data points in the scatter plot.

Ayako claims that there are centers of dilations through which a dilation of line n by a factor of 1. 5 leaves Line n unchanged. Determine whether each point below represents a center of dilation that supports Ayako's claim. Select Yes or No for each point
Points 1 and 3 are centers of dilation supporting Ayako's claim, as they lie on line n. Point 2 is not a center of dilation that supports the claim.
To determine whether each point represents a center of dilation that supports Ayako's claim, we need to understand the properties of dilation. Dilation is a transformation that changes the size of an object without altering its shape. The center of dilation is the fixed point about which the dilation occurs, and the scale factor determines the amount of change in size.
For a dilation of line n by a factor of 1.5 to leave line n unchanged, the center of dilation must lie on line n.
Let's evaluate each point:
1. Yes: If a point lies on line n, it can be a center of dilation that supports Ayako's claim.
2. No: If a point is not on line n, it cannot be a center of dilation that supports Ayako's claim.
3. Yes: If a point lies on line n, it can be a center of dilation that supports Ayako's claim.
In summary, point 1 and point 3 represent centers of dilation that support Ayako's claim, while point 2 does not. The center of dilation must be on line n to leave the line unchanged when dilated by a factor of 1.5.

If peanuts cost $4. 00 per pound and cashews cost $6. 50 per pound, how many pounds of each should he use? Let p = pounds of peanuts and let c = pounds of cashews. Write a system of equations that could be used to solve the problem.
The system of equations that could be used to solve the problem is:
1. p + c = 10 (equation representing the total weight of the mixture)
2. 4.00p + 6.50c = 4.75(10) (equation representing the cost of the mixture)
Let's break down the given information and use it to set up the system of equations.
1. Total weight equation:
The grocer wants to make a 10-pound mixture of peanuts and cashews. Since we are given that p represents the pounds of peanuts and c represents the pounds of cashews, we can write the equation:
p + c = 10
2. Cost equation:
The grocer wants to sell the mixture for $4.75 per pound. The cost of the peanuts is $4.00 per pound and the cost of cashews is $6.50 per pound. To calculate the total cost, we multiply the cost per pound by the weight of each component (peanuts and cashews) and sum them up. This can be expressed as:
4.00p + 6.50c = 4.75(10)
By setting up this system of equations, we can solve for the values of p and c, which represent the pounds of peanuts and cashews, respectively, that the grocer should use in order to make the 10-pound mixture.

a circle of diameter 60cm is cut out of a square of a side 80cm,
calculate the shaded area
The shaded area can be calculated by subtracting the area of the circle from the area of the square. So the shaded area is approximately is 3574 cm².
The given square has a side length of 80 cm, which means it has an area of (80 cm)² = 6400 cm².
The circle is inscribed within the square, and its diameter is given as 60 cm. The radius of the circle is half the diameter, so the radius is 60 cm / 2 = 30 cm. The area of the circle can be calculated using the formula A = πr², where A is the area and r is the radius.
Substituting the values, the area of the circle is A = π(30 cm)² = 900π cm².
To calculate the shaded area, we subtract the area of the circle from the area of the square: Shaded Area = 6400 cm² - 900π cm².
To obtain a numerical approximation, we can use the value of π as approximately 3.14: Shaded Area ≈ 6400 cm² - 900(3.14) cm².
Therefore, the shaded area is approximately 6400 cm² - 2826 cm² ≈ 3574 cm².

Given, Aika is building a square garden. She places a garden post at (3.5, 3.5)
To find: The location of the corner that reflects (3.5, 3.5) across the y-axis.
We know that the y-axis is the vertical line through the point (0,0) and it divides the plane into two parts: left and right. When we reflect a point across the y-axis, the x-coordinate changes sign. For example, the reflection of (2,3) is (-2,3).Therefore, the reflection of (3.5, 3.5) across the y-axis is (-3.5, 3.5)
Since Aika is building a square garden, the corner opposite to (3.5, 3.5) will have coordinates (-3.5, -3.5).

Since a square has all sides equal in length, we divide the perimeter by 4 (the number of sides) to find the length of each side:
Length of each side = 56 inches / 4 = 14 inches
Now, we need to find the height of the pyramid. The slant height given is the distance from the apex of the pyramid to the midpoint of one of the sides. To find the height, we need to use the Pythagorean theorem.
The slant height represents the hypotenuse of a right triangle, with one leg being half the length of the base side and the other leg being the height. Let's call the half of the base length "a" and the height "h."
Using the Pythagorean theorem, we have:
a^2 + h^2 = slant height^2
Since the base side is half the length of the perimeter, we have:
a = 14 inches / 2 = 7 inches
Plugging in the values, we get:
7^2 + h^2 = 25^2
49 + h^2 = 625
h^2 = 625 - 49
h^2 = 576
h = √576
h = 24 inches
Now that we have the length of the base (14 inches) and the height (24 inches), we can calculate the volume of the pyramid using the formula:
Volume = (1/3) * base area * height
The base area of a square is given by side length squared:
Base area = (14 inches)^2 = 196 square inches
Plugging in the values, we have:
Volume = (1/3) * 196 square inches * 24 inches
Volume = (1/3) * 4704 cubic inches
Volume = 1568 cubic inches

A cylinder is 12 cm tall and has a diameter of 3 cmWhat is it's surface area?thx
The surface area of a cylinder can be calculated by adding the areas of its curved surface and its two bases.
Calculate the area of the curved surface: The curved surface area of a cylinder is given by the formula 2πrh,
where r is the radius and h is the height. In this case, the radius is half the diameter, so r = 3/2 cm. The height is 12 cm. Therefore, the curved surface area is[tex]2π(3/2)(12) cm².[/tex]
Calculate the area of the two bases: The base of a cylinder is a circle, so its area is given by the formula πr².
In this case, the radius is 3/2 cm. Therefore, the area of each base is π(3/2)² cm².
Add the area of the curved surface and the two bases to find the total surface area: Surface Area = Curved Surface Area + 2(Base Area).

The mean for Mai's data is 8.9167.
To find the mean of the data given by Mai for the past 12 school days, we need to add all the values together and then divide by the total number of values.
Here is the solution: Given data are: 9, 12, 6, 9, 10, 7, 6, 12, 9, 8, 10, 10
To find: The mean for Mai's data
To calculate the mean, we will add up all the values and then divide by the total number of values.
Mean (average) = sum of values / total number of values
Sum of values = 9 + 12 + 6 + 9 + 10 + 7 + 6 + 12 + 9 + 8 + 10 + 10= 107
Total number of values = 12
Therefore, Mean (average) = sum of values / total number of values
= 107 / 12
= 8.9167 (rounded to four decimal places)
Hence, the mean for Mai's data is 8.9167.

£360 is shared between Abby, Ben, Chloe and Denesh. The ratio of the amount Abby gets to the amount Ben gets is 2 : 7 Chloe and Denesh each get 1. 5 times the amount Abby gets. Work out the amount of money that Ben gets. (4)
The amount of money that Ben gets is £140.
Let's denote the amount Abby gets as 2x. Since the ratio of Abby's amount to Ben's amount is 2:7, the amount Ben gets can be represented as 7x.
Chloe and Denesh each get 1.5 times the amount Abby gets, which means they each get 1.5 * 2x = 3x.
The total amount shared between Abby, Ben, Chloe, and Denesh is £360. So we can write the equation: 2x + 7x + 3x + 3x = £360.
Simplifying the equation, we have: 15x = £360.
Dividing both sides by 15, we find that x = £24.
Substituting x back into the equation for Ben's amount, we get: Ben's amount = 7x = 7 * £24 = £168.
Therefore, Ben gets £140.

If mWVX = (13x + 9)° and mZWXZ = (5x + 36)°, find mZWXY
The value of mZWXY is 103.5° , mWVX = (13x + 9)° and mZWXZ = (5x + 36)°
To find: mZWXY
Here, mWVX and mZWXY are two angles that are formed when the two parallel lines are intersected by a transversal. Therefore,mWVX = mZWXY (alternate interior angles)
and mZWXZ is the third angle that is formed and the sum of the three angles is equal to 180°.
So,mWVX + mZWXY + mZWXZ = 180°
Therefore,mZWXY + mZWXY + (5x + 36)°
= 180°13x + 9 + (5x + 36)°
= 180°18x + 45
= 180°18x
= 180° - 45x
= 135/18x = 7.5
Therefore, mZWXY = mWVX= (13 × 7.5 + 9)°= 103.5°
Hence, the value of mZWXY is 103.5°.
