The number of touchdowns scored by the defense of the professional football team in the season was C. 10 touchdowns.
How to find the number of touchdowns ?The team scored a total of 242 points, and the defense scored about 24% of those points, which is:
0.24 x 242 = 58.08
This means that the defense scored approximately 58 points during the season. If a touchdown is worth 6 points, we can find the number of touchdowns scored by the defense by dividing the total number of points scored by 6:
58 / 6 = 9.67
So the defense scored approximately 9.67 touchdowns during the season. Since we can't have a fraction of a touchdown, the closest whole number answer would be 10 touchdowns.

Answers
For x = 4, the first expression evaluates to:
3(4)(4-2) + 2 = 26
For x = 5, the first expression evaluates to:
3(5)(5-2) + 2 = 47
For x = 4, the second expression evaluates to:
2(4)^2 + 3(4) - 18 = 18
For x = 5, the second expression evaluates to:
2(5)^2 + 3(5) - 18 = 37
Based on these results, we cannot definitively determine whether the two expressions are equivalent, although they may be.
Part 2:
For x = 3, the first expression evaluates to:

Answers
The total price of the 50-inch Panasonic Plasma TV is $687.44.
What is tax?In mathematics, the tax calculation is related to the selling price and income of taxpayers. It is a charge imposed by the government on the citizens for the collection of funds for public welfare and expenditure activities. There are two types of taxes: direct tax and indirect tax.
Given that, 50-65 inch TV's $150 rebate and delivery charge is $35.
50 inch Panasonic Plasma TV costs $734.95
Rebate is $150
So, cost of TV is 734.95-150
= 584.95
Cost of TV including delivery charge
= 584.95-35
= 549.95
Here, tax is 25%
So, cost of TV including tax
= 549.95+25% of 549.95
= 549.95+25/100 ×549.95
= 549.95+0.25×549.95

Using a protractor and a ruler draw a triangle with a side length of 4 inches that is between angles of 50 and 65
Answers
Using a protractor and a ruler we drew a triangle with a side length of 4 inches that is between angles of 50 and 65 as shown in the figure.
What are triangles?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total. The total of a triangle's three sides is the perimeter of the triangle. The space a triangle occupies is known as its area. The area is obtained by taking half of the product of base and altitude.
Now we are asked to draw a triangle with a side length of 4 inches that is between angles of 50° and 65°.
First, let us mark the 50° angle.
Draw a straight line of 4 inches using the ruler as the base.
Keep the protractor on top at one of the ends of the line.
Mark the 50° angle.
Draw a straight line passing through the marked point using the ruler.
Now move the protractor to the other end of the line.
Mark the angle 65°.
Draw a straight line passing through the marked point using the ruler until it meets the 50° angle line.
This is a triangle with angles of 50 and 65 degrees.
Therefore, using a protractor and a ruler we drew a triangle with a side length of 4 inches that is between angles of 50 and 65 as shown in the figure.

Answers
The image was created by translating 5 units down, 5 units up, 1 unit down, and 1 unit up. ABCD and A'B'C'D' are two polygons on the graph.
The first polygon, ABCD, has vertices at (1,-1), (3,-5), (7,-5), and (8,-5). (5,-1). The vertices of the second polygon, A'B'C'D', are located at (1,-6), (3,-10), (7,-10), and (8,-10). (5,-6).
What exactly are vertices?Vertices are points in a geometric figure that define its shape. A vertex is defined mathematically as the intersection of two or more lines, edges, or curves.
We can compare the coordinates of the two polygons to determine the translation that was used to create the image. The first coordinate of the two polygons is (1,-1) and the second coordinate is (1,-1). (1,-6). The y-coordinate difference is 5 units, so the translation is 5 units down. The two polygons' second coordinate is (3,-5) and (3,-10). The y-coordinate difference is 5 units, so the translation is 5 units down.
The second polygon's third coordinate is (7,-5) and (7,-10). The y-coordinate difference is 5 units, so the translation is 5 units down. (5,-1) is the fourth coordinate of both polygons (5,-6). The y-coordinate difference is 5 units, so the translation is 5 units down.

The analysis of the number of runners, can be presented as follows;
a. The sequence is a geometric sequence
b. r(3) = 72, which indicates that the number of runners after the third week is 72
c. r(6)/r(5) = (2/3)
d. The recursive rule for r(w) is that the number of runners in a week is (2/3) × The number of passengers in the previous week
What is a sequence?A sequence is an ordered list of items.
The number of passengers currently in the running club = 243
The amount by which the number reduces each week = 2/3 the number in the previous week.
a. Therefore, the number of passengers each week can be presented as follows;
First week = 243
Second week = (2/3) × 243 = 162
Third week = (2/3)³ × 243
Therefore, the number of runners in the nth week is; an= (2/3)ⁿ × 243, which is a geometric sequence
b. The number of runners in the wth week, r(w) = 2/3)^w × 243,
Therefore; r(3) = (2/3)³ × 243 = 72
The meaning of the value is that the number of runners in the third week, r(3) = 72 runners
c. r(6))/(r(5)) can be obtained as follows;
r(6) = (2/3)^6 × 243
r(5) = (2/3)^5 × 243
r(6)/r(5) = ((2/3)^6 × 243)/( (2/3)^5 × 243) = (2/3)
d. The recursive formula can be obtained as follows;
The number of passengers in a specified week = (2/3) × The number of passengers in the previous week
r(w + 1) = (2/3)^w × 243

What is the maximum height obtained by the baseball?
Answers
In response to the given question, we have that The baseball takes 3 function seconds to reach its highest point as a result.
what is function?Mathematicians research numbers, their variants, equations, associated structures, forms, and possible configurations of these. The word "function" describes the connection between a group of inputs, each of which has a corresponding output. A function is a connection between inputs and outputs where each input results in a single, distinct outcome. Each function has a domain, codomain, or scope assigned to it. Functions are usually denoted by the letter f. (x). An x is entered. On functions, one-to-one capabilities, so multiple capabilities, in capabilities, and on functions are the four main categories of accessible functions.
The formula for the height of the baseball is [tex]h(t) = -4.9t2 + 29.4t + 1.[/tex]
A = -4.9 and B = 29.4 in this instance. The vertex's x-coordinate is as follows:
[tex]x = -b/2a = -29.4/(2*(-4.9)) = 3[/tex]
We need to assess h(3) in order to determine the maximum height:

Answers
We have the following response after answering the given question: equation Hence, there are 22/45 female students at the dance.
What is equation?In a mathematical equation, the equals sign (=), which connects two claims and denotes equality, is utilised. In algebra, an equation is a mathematical statement that proves the equality of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign separates the numbers by a space. Mathematical expressions can be used to describe the relationship between the two sentences on either side of a letter. The logo and the particular piece of software frequently correspond. like, for instance, 2x - 4 = 2.
Now, let's determine how many boys and females attend each school:
Middle School in Colfax
Boys: (5/9) * 270 = 150
Girls: (4/9) * 270 = 120
School in Winthrop:
Boys: (4/9) * 180 = 80
Girls: (5/9) * 180 = 100
Now, we can determine how many males and girls attended the dance overall:
Boys: 150 + 80 = 230
Girls: 120 + 100 = 220
Thus, the proportion of female students attending the dance is:
220 / (230 + 220) = 220 / 450 = 44/90 = 22/45
Hence, there are 22/45 female students at the dance.

Answers
Answer:
(f-g)(x) = -5x^3 + 8x - 8.
(f-g)(-2) = 16.
Step-by-step explanation:
To find (f-g)(x), we need to subtract g(x) from f(x) and simplify:
(f-g)(x) = f(x) - g(x)
= (-5x^3 - 4x^2 + 8x) - (-4x^2 + 8)
= -5x^3 - 4x^2 + 8x + 4x^2 - 8
= -5x^3 + 8x - 8
Therefore, (f-g)(x) = -5x^3 + 8x - 8.
To find (f-g)(-2), we substitute x = -2 into the expression we just found:
(f-g)(-2) = -5(-2)^3 + 8(-2) - 8
= -5(-8) - 16 - 8
= 40 - 24
= 16
Therefore, (f-g)(-2) = 16.
