The points that represent the relationship are (2,4), (5,7), (7,9).
Step-by-step explanation:
1. It is given that Brent was always 2 meters in front of Joel.
2. In the first case, when Joel is at 2 meters, Brent will be 2 meters in front of that, i.e. at 2 meters + 2 meters = 4 meters. Hence, when Joel is at 2 meters distance from the school, Brent will be at 4 meters distance from the school. Hence, the point on the coordinate grid is (2,4) here.
3. Similarly, in the second case, when Joel is at 5 meters, Brent will be 2 meters in front of that, i.e. at 5 meters + 2 meters = 7 meters. Hence, the point on the coordinate grid is (5,7) here.
4. Similarly, in the third case, when Joel is at 7 meters, Brent will be 2 meters in front of that, i.e. at 7 meters + 2 meters = 9 meters. Hence, the point on the coordinate grid is (7,9) here.

Your $54200 2 year car loan is at 15.1% compounded annually. What will you have paid for your car after 2 years?
To find the total amount paid for the car after 2 years, we use the compound interest formula [tex]A = P(1 + r)^n[/tex], where P is the initial loan amount, r is the interest rate, and n is the number of years. Substitute in the given values to calculate the final amount.
Explanation:To calculate the total amount paid for the car after 2 years, we apply the formula for compound interest. The formula is[tex]A = P(1 + r)^n[/tex], where A is the final amount, P is the principal (or initial amount), r is the interest rate, and n is the number of periods. In this case, P = $54200, r = 15.1% or 0.151, and n = 2.
Plugging these values into the formula:
[tex]A = $54200 * (1 + 0.151)^2[/tex].
Once you solve the equation, you will find the total amount paid for the car after 2 years.

Final answer:
Using the compound interest formula, you will have paid $71,787.31 for a $54,200 car loan at 15.1% interest compounded annually after 2 years.
Explanation:
To calculate the total amount paid for a car after 2 years on a loan of $54,200 with an interest rate of 15.1% compounded annually, we'll use the formula for compound interest:
[tex]A = P (1 + r/n)^{(nt)}[/tex]
Where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money)r is the annual interest rate (decimal)n is the number of times that interest is compounded per yeart is the time in yearsFor this car loan:
P = $54,200r = 15.1% = 0.151n = 1 (since interest is compounded annually)t = 2 yearsSubstitute the values into the formula:
A = $54,200 (1 + 0.151/1)^(1*2)
A = $54,200 (1 + 0.151)^2
A = $54,200 (1.151)^2
Calculate the amount:
A = $54,200 * (1.151)^2
A = $54,200 * 1.324301
A = $71,787.31
After 2 years, you will have paid $71,787.31 for your car.
36(1/3)^n-1 first five term of the sequence

The graph shows the number of hours per day spent on social media by a group of teenagers and the number of hours per day spent exercising. A line of best fit for the data is shown.
A scatterplot is shown in the xy-plane. The horizontal axis is labeled as Social Media Hours Per Day and the vertical axis is labeled as Exercising Hours Per Day. The values on the horizontal axis range from 0 to 1.6 in increments of 0.2 and the values on the y-axis range from 0 to 2 in increments of 0.2. The line of best fit intersects the x-axis at a point just to the left of 1 decimal point 4 and y-axis at a point just below 1.1. Majority of the data points are concentrated between 0.3 and 0.6 on the horizontal axis and 0.6 and 0.9 on the vertical axis and two points are marked on the line.
Use the graph to determine how many hours a teenager would spend exercising in one day if they spent 0.25 hours on social media.
Use the graph to determine how many hours a teenager would spend exercising in one day if they spent 1.38 hours on social media.
Do you think the predictions from part (a) and part (b) are reliable? Explain your reasoning.
a)Exercise hour per day is 0.903
b) Exercise hour per day is 0.01573
c) The predicted values are closer to given data points.
What line of best fit?
The line of best fit is a straight line that minimizes the sum of squared differences between observed and predicted values.
From the graph we can find the line equation.
Social media hours per day/1.4 + Exercise hour per day/1.1 = 1
a) If 0.25 hours were spent on social media per day.
0.25/1.4 + Exercise hour per day/1.1 = 1
Exercise hour per day = (1 - (0.25/1.4))*1.1
Exercise hour per day = 0.8215*1.1
= 0.903
b) Social media hours per day/1.4 + Exercise hour per day/1.1 = 1
Given that 1.38 hours were spent on social media
1.38/1.4 + Exercise hour per day/1.1 = 1
Exercise hour per day/1.1 = 1 -(1.38/1.4))
Exercise hour per day = 0.0143*1.1
= 0.01573
c) The predictions from a) and b) are correct because the line almost fits the data points. The line on the data point is minimum error. The line gives the estimated values not the actual values. The predicted values are closer to given data points.

a number c increased 6 by is less than or equal to -26
Answer:
c ≤ - 32
Step-by-step explanation:
It will be less than or equal to - 26 if a number c is increased by 6.
Now, we have to solve the inequality for c.
The inequality is, c + 6 ≤ - 26
⇒ c + 6 - 6 ≤ - 26 - 6 {Subtracting 6 from both the sides}
⇒ c ≤ - 32
Therefore, the solution of the inequality is that c is less than or equal to - 32. (Answer)

Rachel has 3 times as many roses as carnations. She has 12 fewer carnations than daisies. There are 15 daisies. How many flowers does Rachel have in all
Answer:
27 flowers
Step-by-step explanation:
Let
x ----> the number of roses
y ----> the number of carnations
z ----> the number of daisies
we know that
[tex]x=3y[/tex] ----> equation A
[tex]y=z-12[/tex] -----> equation B
[tex]z=15[/tex] -----> equation C
substitute the value of z in equation B
[tex]y=15-12=3[/tex]
substitute the value of y in equation A
[tex]x=3(3)=9[/tex]
so
Rachel have 9 roses, 3 carnations and 15 daisies
In total
9+3+15=27 flowers
Rachel has 15 daisies, 3 carnations, and 9 roses, giving her a total of 27 flowers.
Let's break down the information provided:
Rachel has 3 times as many roses as carnations.She has 12 fewer carnations than daisies.There are 15 daisies.Step-by-Step Solution:
1. Start with the number of daisies: 15 daisies.
2. Rachel has 12 fewer carnations than daisies:
15 daisies - 12 = 3 carnations.
3. Rachel has 3 times as many roses as carnations:
3 carnations * 3 = 9 roses.
4. Add up all the flowers she has:
15 daisies + 3 carnations + 9 roses = 27 flowers in total.
Therefore, Rachel has a total of 27 flowers.

Consecutive odd integers of 201
Question :
The sum of three consecutive odd integers is 201. Find the integers.
Answer:
The Integers are 65,67,69.
Step-by-step explanation:
Let x be any number. when it is multiplied by 2 it becomes an even number.
So, 2x is an even number. Now adding an odd number to 2x , it becomes an odd number
so
First odd number be 2x+1
Second odd number be 2x+3
Third odd number be 2x+5
Now the sum of these three odd number gives 210,
That is
(2x+1) +(2x+3) +(2x+5) = 201
2x+1+2x+3+2x+5 =201
6x + 9 = 201
6x = 201- 9
6x = 192
[tex]x =\frac{192}{6}[/tex]
x = 32
Hence
The first odd number is (2x+1) = (2(32)+1) = 64+1 =65
The second odd number is (2x+3) = (2(32)+3) = 64+3 =67
The third odd number is (2x+1) = (2(32)+5) = 64+5 =69

The ratio of the price of a tv to the price of a computer is 13:15 if the tv 400 dollars cheaper than the computer, how much does the computer cost.
The computer cost is $3000
Step-by-step explanation:
The given is:
The ratio of the price of a tv to the price of a computer is 13 : 15The tv 400 dollars cheaper than the computerWe need to find the cost of the computer
Assume that the price of the computer is $x
∵ The ratio between the prices of the tv and the computer is 13 : 15
∵ The price of the computer is $x
∵ The price of the tv 400 dollars cheaper than the computer
- That means the price of the tv is less than the price of the
computer by $400
∴ The price of the tv is $(x - 400)
By using the ratio method
→ tv : computer
→ 13 : 15
→ (x - 400) : x
By using the cross multiplication
∴ 15(x - 400) = 13(x)
- Simplify the left hand side
∴ 15x - 6000 = 13x
- Add 6000 to both sides
∴ 15x = 13x + 6000
- Subtract 13x from both sides
∴ 2x = 6000
- Divide both sides by 2
∴ x = 3000
The computer cost is $3000

The length of FD = 0.76 feet.
Step-by-step explanation:
Given that in ΔDEF, the angle F measures 90° and the angle D measures 83° and EF=6.2 feet
To find the length of FD, let us use the tangent function. The tangent of an angle is the length of opposite side divided by the length of the adjacent side.
[tex]\tan \theta=\frac{o p p}{a d j}[/tex]
From the given data, θ=83°, [tex]o p p=6.2[/tex] and [tex]a d j=x[/tex]
Substituting these values in the tangent formula, we get,
[tex]\begin{array}{r}{\tan \theta=\frac{o p p}{a d j}} \\{\tan 83^{\circ}=\frac{6.2}{x}}\end{array}[/tex]
Using calculator, the value of [tex]\tan 83^{\circ}=8.14[/tex] and substituting and solving the equation, we get,
[tex]\begin{aligned}8.14 &=\frac{6.2}{x} \\x &=\frac{6.2}{8.14} \\x &=0.76\end{aligned}[/tex]
Thus, the length of FD = 0.76 feet.

What is the length of a rectangle when the length of the rectangle is 2(x+1) meters and the perimeter is 60 meters
Step-by-step explanation:
Given,
The length of a rectangle(l) = 2(x + 1) meters and
The perimeter of a rectangle = 60 meters
To find, the width of a rectangle(b) = ?
We know that,
The perimeter of a rectangle = 2(l + b)
⇒ 2(2(x + 1) + b) = 60
⇒ 2(x + 1) + b =[tex]\dfrac{60}{2} =30[/tex]
⇒ b = 30 - 2(x + 1)
⇒ b = 30 - 2x - 2
⇒ b = 28 - 2x
⇒ b = 2(14 - x)
∴ The width of a rectangle(b) = 2(14 - x)
Hence, the width of a rectangle(b) = 2(14 - x)
