A. 4.0784% compounded monthly
B. 4.0792% compounded quarterly
C. 4.0730% compounded daily
D. 4.0798% compounded semiannually
Answer:
The answer is "Option C"
Step-by-step explanation:
The using formula[tex]= (1+\frac{r}{n})^n -1[/tex]
→r = rate
→ n = compounded value
In choice a:
When compounded is monthly [tex]4.0784\%[/tex]
[tex]n = 12[/tex]
[tex]\to (1+ \frac{0.040784}{12})^{12} = 1.0403-1 = 0.0403[/tex]
In choice b:
When compounded is quarterly[tex]4.0792\%[/tex]
[tex]n = 3\\\\\to (1+ \frac{0.040792}{12} )^{3} = 1.0102-1 = .0102[/tex]
In choice c:
Whenn compounded is daily [tex]4.0730 \%[/tex]
[tex]n = 365\\\\\to (1+ \frac{0.040730}{12})^{365} = 3.328-1 = 2.328[/tex]
In choice d:
When compounded is semiannually[tex]4.0798\%[/tex]
[tex]n = 2\\\\\to (1+ \frac{0.040798}{12})^{2} = 1.0066-1 = 0.0066[/tex]

Jamaal converted the following conic equation from general form to standard form.
amaal converted the following conic equation from general form to standard form.
4x2 + 4y2 – 16x + 24y – 12 = 0
4x2 – 16x + 4y2 + 24y = 12
4(x2 – 4x) + 4(y2 + 6y) = 12
4(x2 – 4x + 4) + 4(y2 + 6y + 9) = 12 + 4 + 9
4(x – 2)2 + 4(y + 3)2 = 25
Jamaal identifies the center of the circle as
(2, –3) and the radius as r = Five-halves.
What error, if any, did Jamaal make ?
Jamaal misidentified the center. The center should be at the point (–2, 3).
Jamaal did not complete the square correctly; he should have added 16 and 36 inside the parentheses in step 4. The radius is r = StartRoot 55 EndRoot.
Jamaal added 4 and 9 to the right hand side in step 4; he should have added 16 and 36. The radius is r = 8.
Jamaal did not make an error.
Answer: C. Jamaal added 4 and 9 to the right hand side in step 4; he should have added 16 and 36. The radius is r=8.
Step-by-step explanation: edge 2020, i took one for the team boys :(
In the given conic equation, Jamaal added 16 and 36 on the left hand side. However, he added 4 and 9 on the right hand side. The radius is r = 8.
What is a general conic equation?
Ax² + Bxy + Cy² + Dx + Ey + F = 0, where x, y are variables and A, B, C, D, E, F are constant terms.
Given,
4x² + 4y² – 16x + 24y – 12 = 0
⇒ 4x² – 16x + 4y² + 24y = 12
⇒ 4(x² – 4x) + 4(y² + 6y) = 12
⇒ 4(x² – 4x) + 16 + 4(y² + 6y) + 36 = 12 + 16 + 36
⇒ 4(x² – 4x + 4) + 4(y² + 6y + 9) = 12 + 16 + 36
⇒ 4(x – 2)² + 4(y + 3)² = 64
⇒ 4(x – 2)² + 4(y + 3)² = (8)²
Therefore, the center is at (2, -3) and the radius is r = 8.
Jamaal must have added 16 and 36 on the rest hand side of the conic equation. That's the mistake Jamaal did. As a result, the value of the radius is wrong when Jamaal solved.

You invest $1,000 in a fund. You check your statement at the end of April and you have lost 13%. When the statement for May comes, you see you have gained 13% in May. What is the value of your account? Round to the nearest dollar.
Answer:
You still would have $1,000
Step-by-step explanation:
In April, you lost 13% of your fund. So we will subtract it.
In May, you gain 13% back. The rate of change was 0%.
Therefore, you still have $1,000 dollars.

Lin and Han's families provide money for their school lunch accounts.
• Han starts with $100 in his account. He spends $15 each week on lunches.
• Lin starts with $25 in her account and does not spend any of it. Her family adds $10 each
week to her account.
1. At the end of 4 weeks, who has more money in their account?
2. After how many weeks will Han and Lin have the same amount of money in their lunch
accounts?
Answer:
1. Lin
2. 3 weeks
Step-by-step explanation:
Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Han starts with $100 in his account. He spends $15 each week on lunches.
Lin starts with $25 in her account and does not spend any of it. Her family adds $10 each week to her account.
For hen:
x be the number of weeks
Total amount left = 100 - 15x
Plug x = 4
Total amount left = $40
For Lin:
y be the number of weeks.
Total amount = 25 + 10y
Plug y = 4
Total amount = 25+40 = $65
Lin has more money in his account.
To have the same amount:
100 - 15x = 25 + 10y
x = y
100 - 15x = 25 + 10x
x = 3 weeks
Thus, Lin has more money in his account, and after 3 weeks Han and Lin will have the same amount of money in their lunch accounts.

Solve the following system of equations:
x − 2y = 14
x + 3y = 9
Answer:
(12, - 1)
Step-by-step explanation:
x - 2y = 14 ......... (1)
x + 3y = 9 ......... (2)
(2) - (1)
(x - x) + (3y - ( - 2y)) = 9 - 14
5y = - 5 ⇒ y = - 1
x + 3( - 1) = 9 ⇒ x = 12
(12, - 1)
A mountain climber records her altitude and the surrounding temperature at various points as she ascends a mountain. She then plots the points on a scatter plot and draws a line of best fit. The equation of the line is y=−3.6x+59 , where x is the altitude in thousands of feet and y is the temperature in degrees Fahrenheit (°F). What does the slope of the equation represent in this scenario?
Answer:
-3.6
Step-by-step explanation:
The general equation of a straight line formula is represented as y = mx + c, where m is the gradient or slope of the line and c is called the intercept on the y-axis.
The equation of the line in the question above is y= −3.6x + 59 ,
Therefore comparing both equations together,
y = mx + c = y = −3.6x + 59
m = -3.6
Therefore, the slope of the equation represent in this scenario is -3.6
