Answer: As the car moves from "BLUE" to "B"L"U"E", it slows down its acceleration, reaches its maximum velocity, and then decelerates. The change in the car's motion is due to the change in the slope of the graph from positive to zero to negative. At "BLUE", the car has the highest positive slope, which represents the maximum acceleration. As the car moves towards "B"L"U"E", the slope of the graph decreases and becomes zero at the highest point of the graph. At this point, the car has reached its maximum velocity, and it starts to decelerate towards "B"L"U"E". Finally, at "B"L"U"E", the slope of the graph is negative, indicating that the car is decelerating.

To solutions for the questions on two quantities are;
1. Time (in hours) and the miles of road paint. The independent quantity is time (t), and the dependent quantity is miles of road painted (m). t for time and m for miles. The equation that relates these two quantities is: m = 9.5 + 0.25t
2. The rate at which the painting crew is painting the road, which is 0.25 mile per hour. This means that for every hour the crew works, they paint 0.25 mile of the road.

How do you solve for the equation on quantities?1. The equation m = 9.5 + 0.25t represents a linear relationship between two variables, m and t.
The equation indicates that the crew has already painted 9.5 miles before they start painting at the rate of 0.25 mile per hour. As the crew continues to work (increasing t), the total miles painted (m) increases by 0.25 miles for every additional hour they work. The equation helps to determine the total miles painted by the crew after a certain amount of time.
If the crew works for another 2 hours, we can find the total miles they will complete using the equation:
m = 9.5 + 0.25(2)
m = 9.5 + 0.5
m = 10
The Department of Transportation in each state is responsible for the improvements and repairs of that state's roads. One important job is to repaint the road lines that have worn away or faded. A painting crew is painting a 24-mile stretch of road. They have already completed a total of 9.5 miles of the road. The crew has been painting at a rate of 0.25 mile per hour and continues to paint at the same rate.
1 Identify the two quantities that are changing in this situation, identify the independent and dependent quantities, and define the variables for these quantities. Then write an equation that relates the two quantities.

Using the intersecting chords theorem, the value of x in the image given is calculated as: x = 17.1.
What is the Intersecting Chords Theorem?The Intersecting Chords Theorem, states that in a circle, when two chords intersect, the products of the lengths of the line segments of one chord are equal to the products of the lengths of the line segments of the other chord.
Mathematically, it can be represented as (segment of one chord) x (segment of same chord) = (segment of other chord) x (segment of same chord).
Therefore, applying the theorem, we have:
x * 7.5 = 9 * 14.25

The length of KH is equal to 7.5 and the length of YB is derived to be 2.05 using the tangent-secant theorem
What is the tangent-secant theoremThis theorem states that if a tangent and a secant are drawn from an external point to a circle, then the square of the length of the tangent segment is equal to the product of the lengths of the secant segment and its external portion.
Given that HN is tangent to the circle, then the triangle HNK is a right triangle and by Pythagoras rule;
KH = √[(4.5)² + 6²]
KH = 7.5
Also, triangle YWM is a right triangle because WY is tangent to the circle so;
YM = √(4² + 9²)
YM = 9.8
WY² = MB × YB {tangent-secant theorem}
4² = (9.8 - YB) × YB {MB = YM - YB}
16 = 9.7YB - YB²
YB² - 9.7YB + 16 = 0
YB = (9.8 ± 5.7)/2 {using the quadratic formula}
YB = 7.75 or YB = 2.05.
In conclusion, the length of KH is equal to 7.5 and the length of YB is derived to be 2.05 using the tangent-secant theorem.

Equation: m=21(p)
Difference: $5
Step-by-step explanation:
To solve this, we first need to figure out an equation for Company R.
We know that Company S's equation is m=26(p). this means that the amount reimbursed is 26 times the amount of aluminum returned.
210/10=21
Company R's equation is m=21(p). We know this because throughout the table, the amount reimbursed is always 21 times more than the amount of aluminum returned.
Now that we have two equations, we can solve. 26-21=5.
Therefore, the difference between the amount reimbursed per pound is $5. (As long as there is not another variable, this should be the answer for part b)

The measure of ∠1 is 54 degrees.
Given information:
In a triangle, there are three interior angles 1, 2, and 3.
m∠3 = 55°.
∠2 and 109° are the supplementary angles.
To find ∠1:
The sum of the interior angles of a triangle is always 180 degrees. So we can use this fact to find the measure of ∠1.
m∠2 + m∠3 + m∠1 = 180°
We are given that m∠3 = 55°, and that ∠2 and 109° are supplementary angles, which means that they add up to 180 degrees.
m∠2 + 109° = 180°
Subtracting 109° from both sides, we get:
m∠2 = 71°
Now we can substitute the values we know into the first equation and solve for ∠1:
m∠2 + m∠3 + m∠1 = 180°
71° + 55° + m∠1 = 180°
126° + m∠1 = 180°
Subtracting 126° from both sides, we get:
m∠1 = 54°.

A composite figure is represented in the image.
21 POINTS!!!
A six-sided composite figure. A vertical line on the left is labeled 4 meters. The base is labeled 9 meters. There is a small portion from the vertical line that is parallel to the base that is labeled 3 meters. This portion leads to two segments that come to a point, and from that point, there is a height of 3 meters labeled.
What is the total area of the figure?
Answers
The total area of the figure is 216 m².
Step-by-step explanation:To find the area of the six-sided composite figure, we can divide it into two smaller shapes: a rectangle and a triangle.
The rectangle has a length of 8 meters and a width of 18 meters, so its area is:
8 meters × 18 meters = 144 square meters
The triangle has a base of 18 meters and a height of 8 meters, so its area is:
(1/2) × 18 meters × 8 meters = 72 square meters
The total area of the six-sided composite figure is the sum of the areas of the rectangle and the triangle:
144 square meters + 72 square meters = 216 square meters
Therefore, the total area of the figure is 216 m².

If the area of the shaded region in the diagram below is 103 square feet, what are the dimensions of the inside rectangle? Show your work.
(Please ignore my work, it doesn't go anywhere.)
Answers
(3x-2)(x+6)=103 + (x-1)(2x) because the formula for area is length x width. First parentheses represent length and second represents width. Then, if the shaded region is listed as 103, the unshaded part’s area can be written as length x width.
Solve for x by using the FOIL method or the table method, as you did in your work.
3x^2 - 20x - 12 = 3x^2 - 2x + 103
Here’s a helpful tip- whenever you get the same term on both sides of an equal sign, you can just erase them because they cancel each other out. This is because if you go on the opposite side of an equal sign, you do the inverse operation (example- +40 turns into -40 on the other side).
Simplify and it becomes -22x-115.
-22 is a factor of -115. Divide them and you get 5.
-22(x-5).
Since this is a quadratic equation, to find x, you set it equal to 0.
-22(x-5) = 0.
We know that at least one of the two factors must be 0, because anything multiplied by 0 equals 0. If -22 is not equal to 0, it must be x-5.
x-5=0.
Simplify and use the inverse operation.
x=5.
Then, substitute it back into the dimensions of the inside rectangle and you get

10 students are watching a 2 hour and 42 minute long movie. Let S represent the number of students and M represent the number of minutes in that movie. If a different movie is 1 hour and 31 minutes, how many students are watching it?
Answers
If 10 students are watching a 2 hour and 42 minute long movie. 6 students are watching the second movie.
How many students are watching it?We can use proportions to solve this problem. Let's start by finding the total number of minutes in the first movie:
M = 2 hours x 60 minutes/hour + 42 minutes = 120 minutes + 42 minutes = 162 minutes
Now, we can set up a proportion to find the number of students watching the second movie:
S/M = S'/M'
where S is the number of students watching the first movie (which we know is 10), M is the number of minutes in the first movie (162), S' is the number of students watching the second movie (which we want to find), and M' is the number of minutes in the second movie (91).
Substituting in the values we know and solving for S', we get:
10/162 = S'/91
S' = (10 x 91) / 162 = 5.62
Since we can't have a fractional part of a student, we need to round our answer to the nearest whole number. Therefore, approximately 6 students are watching the second movie.
