Answer:
width = 6 feet
length = 19 feet
Step-by-step explanation:
'w' = width
'2w+7' = length
50 = 2w + 2(2w+7)
50 = 2w + 4w + 14
36 = 6w
6 = w
length = 2(6)+7 = 19
A diamond ring increases in value at a rate of 5% per year. If the ring was purchased for $1200, which equation would calculate how much will it be worth in 30 years?
Would it be
A - y = 1200(1+.05)^30
B - y = 30(1+.05)^1200
C - y = .05(1+1200)^30
Answer:
A - y = 1200(1+.05)^30
Step-by-step explanation:
In this case, you need to calculate the future value and the formula to calculate that is:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:
FV=1200*(1+0.05)^30
According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.

Find the mean of the data.
A bar graph, titled “Visits to Your Website”. The vertical axis is labeled “Number of visits”. The horizontal axis is labeled “Day”. For bar 1, the height is 12. For bar 2, the height is 16. For bar 3, the height is 0. For bar 4, the height is 8. For bar 5, the height is 31. For bar 6, the height is 28. For bar 7, the height is 17.
12, 16, 0, 8, 31, 28, 17
12 + 16 + 0 + 8 + 31 + 28 + 17 = 112
112 / 7 = 16

Which statement BEST describes why the exponential function exceeds the linear function?
A) The exponential function has no negative y values.
B) As exponential functions will always exceed a linear function.
C) The exponential function has a lower initial value than the linear function.
D) The linear function has a higher initial value than the exponential function.
Answer:
A
Step-by-step explanation:
A is correct. The graph of the basic exponential function neither touches nor crosses the x-axis, whereas a linear function does cross over and can be negative for some inputs.

BEST ANSWER GETS BRAINLIEST
First, you need to come up with an activity. If you are having trouble thinking of what to do, here are some ideas:
How many jumping jacks can you do in a minute?
How many times can you write your full address in a minute?
How many points can you score in a game in 3 minutes?
How many pages of a book can you read in 4 minutes?
How far can you walk in 5 minutes?
Feel free to be creative or even to come up with an activity you think your teacher has not seen before.
Now that you have decided what your activity is going to be, it’s time to get started.
Part 1: Record Information
Spend a short amount of time (one to five minutes) doing your activity. Answer the following questions:
What was the activity?
How long did you spend doing your activity?
How much of the activity did you complete in the time period? (Example: I did 24 sit-ups in one minute).
Which of these variables is your dependent variable?
Which one is the independent variable?
Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio language can help.)
(Questions 1 to 3 are worth 1 point each; questions 4 to 6 are worth 2 points each.)
Part 2: Prepare a Table
Assuming that you could complete the activity at the same rate over different time periods, how much of the activity could you complete in two minutes, three minutes, four minutes, and five minutes? (Note: If you spent two minutes doing your activity, then you should edit the table below and use multiples of 2 up to 10).
You may use the table below for your variables.
Time
(minutes)
0 0
1
2
3
4
Part 3: Prepare a Graph
Create a graph to show your relationship. Make sure you include all the parts for a graph and show the data clearly. Include a title for the graph and label the x- and y-axes.
Part 4: Write an Equation
Based on your recorded values, write an equation that represents the relationship between the time you spent doing the activity and the amount of the activity you completed. Make sure to define your variables.
Follow-up Questions
If you were able to maintain this rate of your activity for 12 minutes, how much of the activity would you be able to complete?
How long would it take you to reach 100 for the number of times you did your activity?
Which representation do you believe is the best way to share this information with someone else? This is your opinion. No answer is right or wrong.
(Question 1 is worth 1 point; questions 2 and 3 are worth 2 points each.)

Select the shape that can be shown congruent to this shape below by a rotation? A) A B) B C) C D) D
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the original shape and possible options to select from are not given.
I will use the attached plot to provide a general explanation to answer this solution.
In the attachment, the original image is represented with shape O and the dimension is: 3 by 4 units
Rotation is a rigid transformation, and as such it does not alter the dimension of the original to form a new image.
From the attachment, we have
The dimension of A to be: 4 by 3
The dimension of B to be: 5 by 4
The dimension of A and O are the same; this means that they are congruent.
However, the dimension of B and O are not the same; this means that they are not congruent

A truck was purchased for $25,000 in 2020 and each year its value decreases by 7%. How much will the truck be worth in
2026?
Answer:
$3787.5
Step-by-step explanation:
Given data
Cost price= $25,000
Rate of decrease= 7%
Time= 2020-2026= 26 years
Let us apply the formula
A= P(1-r)^t
substitute
A= 25000(1-0.07)^26
A=25000(0.93)^26
A= 25000*0.1515
A= $3787.5
Hence the worth will be $3787.5
