The total amount of candy sold at Cassandra's Candy Corner can be represented by the function C(x) = 4x3 + 16x2 + 60x + 648, where x represents the number of years since the store opened. The amount of types of candy can be modeled by the linear function T(x) = 2x + 12. Which expression represents the amount of candy sold each year per type at Cassandra's Candy Corner?
4x3 + 16x2 + 58x + 636
4x3 + 16x2 + 62x + 660
2x2 – 4x + 54
2x2 + 4x + 54
The expression which correctly represents the amount of candy sold each year per type at Cassandra's Candy corner is; 2x2 – 4x + 54.
Polynomial divisionIt follows from the task content that the expression which shows the amount of candy sold each year per type is to be determined.
Since, the function, C (x) = 4x³ + 16x² + 60x + 648 represents the total amount of candy sold while, T(x) = 2x + 12 represents the amounts of types of candy.
Therefore, the amount of candy sold each year per type is; C(x) ÷ T(x).
Hence, the result of the polynomial division as in the attached image is; 2x² - 4x + 54.
Ultimately, the amount of candy sold each year per candy is represented by the expression; 2x² - 4x + 54.

The surface area of the figure is calculated as 150.72 [tex]mi^2[/tex] and when rounded off to the nearest hundredth, it comes out as 151 [tex]mi^2[/tex].
What is Surface area?A solid object's surface area can be stated as a measurement of the overall space that the object's surface takes up. As an alternate, surface area can also be described as the area of the entire outer part, or which is said as the uppermost layer of any kind of 3D object.
Square units are used in the calculation. The total area of all the outside surfaces makes up the surface area of a three-dimensional object, which is also expressed in square units.
As an example, we can take that in order to find the exact surface area of a cuboid, we have to add the areas of all 6 faces.
In this figure, we can see that it can be stated as a cylinder.
So, as we know the formula of the surface area of a cylinder can be written as:
2[tex]\pi[/tex]rh + 2[tex]\pi r^2[/tex]
Here r = 8/2

For finding the equivalent number, we divide 6 by 10:
6 / 10 = 0.6
0.6 is the equivalent number
We have 6 in the numerator and 10 in the denominator, if we calculate any mathematical operation to both, we will find the equivalent fractions.
Let's see two examples:
1. Let's divide by 2:
6 divided by 2 is 3; and 10 divided by 2 is 5. Then our new equivalent fraction is
[tex]\frac{3}{5}[/tex]2. Let's multiply by 3:
6 multiplied by 3 is 18; 10 multiplied by 3 is 30. Then a second equivalent fraction is:
[tex]\frac{18}{30}[/tex]We can calculate additional equivalent fractions, using the same operation for both: numerator and denominator.
For calculating the equivalent fraction in hundreds, we will use the initial decimal equivalent we calculated at the beginning: 0.6
0.6 = 6/10 and we multiply it by 10 numerator and denominator
6 * 10 = 60 and 10 * 10 = 100. Then the fraction is 60/100
20 divided by 10 is 2 and 100 divided by 10 is 10, so the equivalent fraction is 2/10
This case is exactly the same than the previous we solved:

A transformative sequence is a particular arrangement of transforming events. This suggests that a series of transformations may manage more than one transition, and that the order in which they occur is crucial. A and B are similar in this case.
Congruent is what?When two figures or objects in geometry have the same shapes, sizes, or are mirror images of one another, they are said to be congruent.
Formally, two sets of points are said to be congruent if, and only if, an isometry, which is a collection of rigid motions including translation, rotation, and reflection, can transform them into one another.
This shows that resizing an object will not allow it to be properly aligned with another object, only by moving and reflecting it. Therefore, two independent plane figures on a piece of paper are congruent if we can cut them out and then precisely line them up. The paper might be distributed.
Each box is the same size in terms of length and width. The only change is where the figure is located.
Transformations can be divided into four categories: translation, rotation, reflection, and dilation.
Two figures are said to be "congruent" if they can be positioned perfectly over one another. Congruent refers to things that are exactly the same size and shape.

parallelogram ABCD is below. m < D = 130° and m < B = (3x-1.5)° . solve for x and round to the nearest whole number.
Given:
m∠D = 130 degrees
m∠B = (3x - 1.5) degrees
Let's solve for the value of x.
A parallelogram is a quadilateral that has equal opposite angles and equal opposite sides.
Since a parallelogram has equal opposite angles, measure of angle D and measure of angle B are equal.
Thus, we have the equation:
m∠B = m∠D
(3x - 1.5) = 130
Solve for x.
Remove the parentheses:
3x - 1.5 = 130
Add 1.5 to both sides:
3x - 1.5 + 1.5 = 130 + 1.5
3x + 0 = 131.5
3x = 131.5

The function is given by the equation;
g(x) = -x² - 9x + 27
The interval of the function lies as;
-9 ≤ x ≤ -1.
Let,
a = -1 ans b = -9
Then,
g(a) = g(-1), Put x = -1 in the function.
g(-1) = -(-1)² - 9(-1) + 27
g(-1) = 35
Now, g(b) = g(-9), Put x = -9 in the function.
g(-9) = -(-9)² - 9(-9) + 27
g(-9) = 27
Thus, the average rate of change of the function is-
Average rate of change = [g(a) - g(b)]/[a - b]
