Answer: A) x2+y2+16x-8y+73=0
Step-by-step explanation:
I got it right on edge.
The generic version of the circle equation is, x² + y² + 16x - 8y + 73 = 0.
Definition of circle:
A circle is a closed two-dimensional object in which all points in the plane are equidistant from a single point known as the "centre." The line of reflection symmetry is formed by every line that travels through the circle. For any angle, it also exhibits rotational symmetry around the center.
Step-by-step:Step 1:
The conventional form of the circle equation is expressed as:
(x - a)² + (y - b)² = r²
where centers are specified as (a,b)
The circle equation given in the question is:
x² + y² = 7
If the circle is translated T(-8,4), the center of the translated circle is located at (-8,4).
As a result, the conventional version of the circle equation is:
(x + 8) ² + (y - 4) ² = 7
Step 2:
Simplifying the problem:
(x² + 64 + 2(x)(8)) + (y² + 16 - 2(y)(4)) = 7
x² + 64 + 16x + y² + 16 - 8y = 7
x² + y² + 16x - 8y + 80 = 7
x² + y² + 16x - 8y + 80 - 7 = 0
x² + y² + 16x - 8y + 73 = 0
which is the generic version of the circle equation.

There are 500 coffins and 500 hundred men who need them.The undertaker asks the first man to go to every coffin and open them,then he tells the 2nd man to go to every one and close it.The 3rd one goes to every 3rd coffin and so on.How many are open?
Answer:
22
Step-by-step explanation:
No coffin will be opened at the end of 500th man .
Given,
500 coffins and 500 hundred men
Here,
First man opens all the coffins, but the second man closes every second coffin, which means that the odd-numbered coffins are closed again.
Then, the third man goes to every third coffin and closes it, which means that the coffins that are multiples of 3 are closed again.
This pattern continues with each subsequent man, so by the time the 500th man goes to the coffins, all of them will be closed.

Final answer:
To create a new model for the total sales of green tea and fruit juice, the sales equations for both products are added together and simplified, resulting in the model A = 3t² + 1093, representing combined sales in billions as a function of time in years.
Explanation:
To find a new model A for the total number of new green tea and fruit juice sales, we need to combine the models given for G (green tea sales) and J (fruit juice sales). The models provided had some errors, but they should be:
G = 674 + 3t – 2t² + 5t + 60
and
J = 314 – 3t + 5t² – 5t + 45
Combining these models to form A (total sales), we add G and J together:
A = G + J
= (674 + 3t – 2t² + 5t + 60) + (314 – 3t + 5t² – 5t + 45)
Now, we simplify the equation by combining like terms:
A = (674 + 314) + (3t – 3t) + (5t – 5t) – 2t² + 5t² + (60 + 45)
A = 988 + 0t + 0t + 3t² + 105
A = 988 + 3t² + 105
A = 3t² + 1093
Therefore, the new model A for the total sales is A = 3t² + 1093. This model represents the combined sales of green tea and fruit juice in billions of dollars during the 20-year period as a function of time t in years.
Matthew bought a laptop for $34,000 in the year 2008. Its value depreciates by 4% per year. What is the
value of laptop in 2011?
The value of the laptop in 2011 will be $29920
Step-by-step explanation:
Cost of the laptop = $34000
Rate of decrease in value per year = 4%
Total time = 3 years
The Value decrease in 2011 = (34000 x 4 x 3) /100
= $4080
The value of the laptop in 2011 = 34000-4080
= $29920
The value of the laptop in 2011 will be $29920

Charlie has a $55 per month cell phone plan. The sales tax on his plan is 8%. Which expressions can be used to determine how much Charlie will pay each month in total (including tax)? (Select the TWO correct responses)
Option 4 55(108/100)
Option 2 55(0.08)
Option 3 55(8/100)
Option 1 55(1.08)
Answer:
The correct answers are Option 4 55(108/100) and Option 1 55(1.08)
Step-by-step explanation:
To begin, we must analyze the information we have and establish the result, in order to compare it with the results of the operations that the answers offer.
We know that the total Charlie pays for his cell phone plan is $ 55 + 8% tax.
One of the possible ways in which you can calculate a percentage would be in this case:
(55.8) : 100
440 : 100 = 4.40
This indicates that the tax was 4.4 added to 55, giving us a total of 59.4.
Now we just have to check that options 4 and 1 are correct. Let's see:
55 (108/100) =
55 (1.08) = 59.94
This last section is exactly the same as option 1, which also makes it a correct answer.
Ronald works in an Ornithology (bird maintenance) department. Students asked him to find out the best estimate of the local bird population. So he tied a belt around the legs of 40 birds. A few days later, he observed 520 birds, 34 of which had belts. To the nearest whole number, what is the best estimate for the bird population?
Answer:
618 birds.
Step-by-step explanation:
Let the estimated number of birds=x
Out of x birds, he tied a belt around the legs of 40 birds.
When he observed 520 birds, 34 of which had belts.
Expressing each as a ratio
[tex]\frac{x}{40}=\frac{520}{34}[/tex]
Cross Multiply
34x=520X40
x=520X40÷34=611.7≈618
There are an estimated 618 birds.
Answer:
The best estimate for the bird population is 613 birds
Step-by-step explanation:
Let x be the total of number of estimated bird
From x, 40 birds are with belt
he observed 520 birds, 34 of which had belts.
Then taking reciprocal of both statements
x/40 = 520/34
34x = 520*40 = 20800
x = 20800/34
x = 613The total of number of estimated birds is 613 birds
The total of number of estimated birds is 613 birds

Angles 1 and 2 are complementary. If ∠1 measures 56°, what is the measure of ∠2?
Final answer:
To find the measure of angle 2, which is complementary to angle 1 with a measure of 56°, subtract 56° from 90°, resulting in angle 2 measuring 34°.
Explanation:
If angles 1 and 2 are complementary, it means that the sum of their measures is 90 degrees. Since the measure of ∠1 is given as 56°, we can find the measure of ∠2 by subtracting the measure of ∠1 from 90 degrees:
Measure of ∠2 = 90° - Measure of ∠1
Measure of ∠2 = 90° - 56°
Measure of ∠2 = 34°
Therefore, the measure of ∠2 is 34 degrees.
35 total girls and 50 total boys were surveyed. How
many students bought their lunch from the cafeteria?
Round to the nearest whole number.
students
Answer:
36 students
Step-by-step explanation:
right on edge
The total number of students bought their lunch from cafeteria is 36.
Given data:
The total number of girls is 35 and the total number of boys is 50.
Probability of boys bought their lunch from cafeteria = 0.44
Since total no. of boys =50
So, number of boys bought their lunch from cafeteria P ( B ) = 50*0.44
And, the value of P ( B ) = 22
Probability of girls bought their lunch from cafeteria = 0.4
Since total no. of girls =35
So, number of girls bought their lunch from cafeteria P ( G ) = 35*0.4
So, the value of P ( G ) = 14
The total number of students , n = P ( B ) + P ( G )
So, n = 22 + 14
n = 36
Hence , the number of students is 36

The measure of angle ABC is 74 degrees.
What is the measured angle of ABC?Given:
The measure of ABD is 37 degrees.The measure of BCD is 90 degrees.The measure of DAB is 90 degrees.Find:
The measure of ABC.Solution:
As we know that BAD is forming a triangle that will have 180 degrees if all the angles of the triangles are summed together.
So, ABDA=180 degrees.
Now, ADB=180-(ABD+DAB)=180-(90+37)=180-127=53 degrees.
So, 90+37=127 degrees and 90+53=143 degrees.
Now, we will subtract them to get CBD,
CBD=143-127=37 degrees.
Therefore, ABC= CBD+ABD=37+37=74 degrees.
Hence, the measure of angle ABC is 74 degrees.
Therefore, option (B) is the correct answer.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,228 was collected on the
sale of 1,340 tickets. How many of each type of ticket were sold?
Answer:
Okay, so 2 years later, here's your answer.
472 adult tickets and 868 student tickets were sold.
Step-by-step explanation:
Let x be the number of adult tickets sold.
Let y be the number of student tickets sold.
Your Equations:
x + y = 1340 tickets
5x + (1)y = $3228
Isolate the y variable:
y = 1340 - x
y = 3228 - 5x
Substitute:
1340 - x = 3228 - 5x
Solve:
1340 - x = 3228 - 5x
Add 5x on both sides
1340 + 4x = 3228
Subtract 1340 on both sides
4x = 1888
Divide 4 on both sides
x = 472
Plug in x into an equation:
472 + y = 1340
Subtract 472 on both sides
y = 868
472 adult tickets were sold
868 student tickets were sold.

Find the circumference and the area of a circle with radius 5 cm.
Write your answers in terms of n, and be sure to include the correct units in your answers.
The circumference of the circle is 10π cm, and the area is 25π cm².
The formulas for the circumference (C) and area (A) of a circle in terms of
the radius (r) are:
Circumference (C) = 2πr
Area (A) = πr²
Given that the radius (r) is 5 cm, we can substitute this value into the formulas:
Circumference (C) = 2π(5) = 10π cm
Area (A) = π(5)² = 25π cm²
So, the circumference of the circle is 10π cm, and the area is 25π cm².
Score on a test are normally distributed with a mean of 63.2 and standard deviation of 11.7 find, P 81 which separates the bottom81% from top 19%
Answer:
P 81 = 73.5
Step-by-step explanation:
This is a normal distribution problem with a mean of 63.2 and standard deviation of 11.7.
Let the number that separates the bottom 81% from the top 19% be x' and let it's z-score be z'.
P(x ≤ x') = P(z ≤ z') = 0.81
Using the normal distribution table,
z' = 0.878
But note that the z-score for any value is that value minus the mean divided by standard deviation.
z' = (x' - μ)/σ
0.878 = (x' - 63.2)/11.7
x' = 73.4726 = 73.5 to 1 d.p
Hope this Helps!!!
Final answer:
To find the value that separates the bottom 81% from the top 19%, you can use the z-score formula and the given mean and standard deviation to calculate the desired value.
Explanation:
To find the value that separates the bottom 81% from the top 19%, we need to find the z-score corresponding to the 81st percentile.
Using the formula Z = (X - μ) / σ where X is the given value, μ is the mean, and σ is the standard deviation, we can rearrange it to solve for X as:
X = Z * σ + μ
Since we know the mean is 63.2 and the standard deviation is 11.7, we can calculate the z-score corresponding to the 81st percentile (0.81) using the standard normal distribution table or a calculator.
Once we have the z-score, we can substitute it into the formula to find the corresponding value.

jane and jill were simplifying the expression (2x2+x) +2(-x2+×) and obtained different answers . who is right and why?
Jane is correct because Jane correctly simplified the expression to [tex]\(3x\)[/tex].
Let's carefully simplify the expression [tex]\((2x^2 + x) + 2(-x^2 + x)\)[/tex] step-by-step to determine who is correct, Jane or Jill.
Starting with the given expression:
[tex]\[(2x^2 + x) + 2(-x^2 + x)\][/tex]
We first distribute the [tex]\(2\)[/tex] in [tex]\(2(-x^2 + x)\):[/tex]
[tex]\[(2x^2 + x) + (-2x^2 + 2x)\][/tex]
Next, we combine like terms. We combine the \(x^2\) terms and the \(x\) terms separately:
[tex]\[(2x^2 - 2x^2) + (x + 2x)\][/tex]
Simplify each group of like terms:
[tex]\[0x^2 + 3x\][/tex]
This simplifies to:
[tex]\[3x\][/tex]
Therefore, the correct simplification of the expression [tex]\((2x^2 + x) + 2(-x^2 + x)\) is \(3x\)[/tex].
Jane’s solution is:
[tex]\[\begin{aligned}& = (2x^2 + x) + 2(-x^2 + x) \\& = (2x^2 + x) + (-x^2 + x) + (-x^2 + x) \\& = (2x^2 - x^2 - x^2) + (x + x + x) \\& = 3x\end{aligned}\][/tex]
Jill’s solution is:
[tex]\[\begin{aligned}& = (2x^2 + x) + 2(-x^2 + x) \\& = (2x^2 + x) - 2x^2 + 2x \\& = 2x\end{aligned}\][/tex]

This set of ordered pairs is a function (22, 4), (21, 1), (0, 0), (1, 1), and (2, 4).
Please explain like you were teaching how you can know this is a function.
Answer:
Step-by-step explanation:
You know these ordered pairs are considered a function, because the x intercepts do not repeat themselves. In other words, each input numbers are different. If these ordered pairs were not a function, the x intercept would be repeating. For example, 22 is already a x intercept, (22,4), if 22 was put in as another x intercept like,(22,1) these ordered pairs would not be a function.
