The standard form of the equation of the circle is:
\((x-h)^2+(y-k)=r^2\)Therefore, the equation of a circle centered in (3,2)=(h,k) and radius r=3 is:
\(\begin{gathered} (x-3)^2+(y-2)^2=3^2=9 \\ \Rightarrow(x-3)^2+(y-2)^2=9 \end{gathered}\)The last line is the equation of the circle in the standard form we are looking for.
The center of the circle and its radius is given by the problem, as far as I can see, and those are (3,2) and 3 respectively.
What value is equivalent to 3 x 12 / (4 + 2) ? Answer to work the problem is 6. Is that the value? I’m reading the expression as tho there should be a variable
Answer:
6
Step-by-step explanation:
3x12 = 36
(4+2) 6
simplify
36/6=6
The value is indeed 6 and there shouldn't be a variable because if there is, then there should be a variable in the question.
The simplified form of the expression (3 × 12)/(4 + 2) is 6.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression (3 × 12)/(4 + 2).
Now, 12×3 is 36, and (4 + 2) is 6.
Therefore the simplified form of the expression is,
= 36/6.
Now, we know that 6 times 6 is 36 so, 36 divided by 6 the quotient should be 6.
Therefore,
36/6.
= 6.
So, The value of the expression (3 × 12)/(4 + 2) is 6.

Write a statement that correctly describes the relationship between these two sequences: 2, 4, 6, 8, 10 and 1, 2, 3, 4, 5.
Answer:
The equation a + d(n-1)
Step-by-step explanation:
Where a is the first number in the sequence, d is the common difference and n is the position of a certain number in the series, e.g
1, 2, 3, 4, 5: a = 1, d = 1 (because 2-1=1, 3-2=1, 4-3=1, etc) and n = 1,2,3...
2, 4, 6, 8, 10: a = 2, d = 2 (because 4-2=2, 6-4=2, etc) and n = 1,2,3,4,5...
So for the second sequence, we could try to get the value of n in n = 6 as follows:
a + d(n-1) where a = 2, n = 6 and d = 2
Thus, 2 + 2(6-1) = 2 + 2(5) = 2 + 10 = 12
So the sixth number in the series would be 12

Question :For each value of x determine whether it is a solution to 45 = -9 ( x + 5 )
Given :In the question we have given an equation i.e. :
45 = -9 ( x + 5 )In the question values of x are also given i.e. :
5-71-4To Determine :In this question we have to determine whether given value of x are solution fo the given equation or not .
How we have to solve this question :We are solving this question by substituting given value of x in the equation if equation satisfied then it means that the value for x is solution of the equation .
So Let's get started :1) Value of x as 5 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as 5 :
45 = -9 ( 5 + 5 )45 = -9 ( 10 )45 = -90But , 45 is not equal to -90Therefore , 5 is not the solution for equation .
2) Value of x as -7 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as -7 :
45 = -9 ( -7 + 5 )45 = -9 ( -2 )45 = 18But , 45 is not equal to 18Therefore , -7 is not the solution for equation .
3) Value of x as 1 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as 1 :
45 = -9 ( 1 + 5 )45 = -9 ( 6 )45 = -54But , 45 is not equal to -54Therefore , 1 is not the solution for equation .
4) Value of x as -4 :
45 = -9 ( x + 5 ) ( Given Equation )Now substituting value of x as -4 :
45 = -9 ( -4 + 5 )45 = -9 ( 1 )45 = -9But , 45 is not equal to -9Therefore , -4 is not the solution for equation .

(-4) +9 = 5 and -2.(-5) - 3 = 7 ✓ Because 1 • (-9) + 9 = 0 and -2 • (-1) - 3 - 0 Because 1 • (-5) + 9 = 4 and 2 • (-4) - 3 = 5 Because 1. (-4) + 9 = 5 and -2 • (-4) - 3 = 5
the given expression is,
y = x +9 & y = -2x -3
so the solution for both the line will be the intersection point of the lines,

Jim’s parents paid for the first three years of his college costs. When he was a college senior, he was approved for an unsubsidized loan in the amount of $15,200 at a 4.29% interest rate for 10 years.
If he chooses to make interest-only payments until the monthly loan payments are due, for
how long will he be making interest only payments?
What is the total amount of his interest only payments?
If he begins the loan replacement with no interest capitalization because he already paid the interest when he was in school and during the 6 month grace period, how much will he have paid in interest for this loan by the end of the 10 year loan period?
1. If Jim chooses to make interest-only payments until the monthly loan payments are due, he will make interest-only payments for 1 year and 6 months or 1¹/₂ years.
2. The total amount of Jim's interest-only payments is $978.12.
3. If Jim starts the loan repayment with no interest capitalization, the total interest he has to pay on the student loan after the grace period is $6,520.80.
What is the grace period?Graduating students enjoy a six-month grace period before repaying their student loans.
The grace period enables the graduates to get employment and earn income.
Unsubsidized student's loan = $15,200
Interest rate = 4.29%
Loan period = 10 years
Length of interest-only payments = Senior Year + 6 months Grace Period
= 1 + ¹/₂
= 1¹/₂ years
0r 18 months.
Interest-only amount during the 1¹/₂ years = $978.12 ($15,200 x 4.29% x 1.5)
Interest payments after the grace period = $6,520.80 ($15,200 x 4.29% x 10)
Total payments for the loan = Unsubsidized loan + Interest-only payments + Interest payments after the grace period.
= $22,698.92 ($15,200 + $978.12 + $6,520.80)
Thus, Jim's total payments before, during, and after the grace period are $22,698.92.

Answer:
Reflection over the x-axis and shifted 3 units to the left
Step-by-step explanation:
From the parent graph f(x) = \(-4^x\), we can conclude that:
1. Reflected over the x-axis because we multiplied by -1 to flip it to positive.
2. Horizontally shifted the graph to the left because of the +3 (take the opposite for horizontal movement)
That is how we get f(x) = \(4^{x+3}\).

Graph by completing the square x2-2x+y2+6y-6=0
The equation in the standard form of a circle and find the centre and radius:
(x - 1)²/31 + (y + 3)²/31/3 = 1
To graph by completing the square, we need to rearrange the equation so that it has the form:
(x - h)² + (y - k)² = r²
Starting with x² - 2x + y² + 6y - 6 = 0:
First, we can factor out a 2 from the x terms and a 6 from the y terms:
2(x² - 2x) + 6(y² + 6y) - 6 = 0
Next, we need to complete the square for the x and y terms:
2(x² - 2x + 1) + 6(y² + 6y + 9) - 6 = 2(1) + 6(9)
Simplifying, we get:
2(x - 1)² + 6(y + 3)² = 62
Now we can rewrite the equation in the standard form of a circle and find the centre and radius:
(x - 1)²/31 + (y + 3)²/31/3 = 1

We want to calculate the volume of the spherical shell of chocolate.
The chocolate shell is spherical with a thickness of 0.5cm
Volumes of spherical shells can be calculated with the formula;
\(V_{shell}=\frac{4}{3}\pi(R^3-r^3)\)The outer diameter is 8cm. The outer radius is therefore 4cm
The inner diameter is 8-2(0.5)=7cm. The inner radius is therefore 3.5cm
Therefore, we can find the volume of the chocolate shell as;

Step-by-step explanation:
Let's call the width of the rectangle "w".
The length of the rectangle is given as 2 inches more than 3 times the width:
l = 3w + 2
When the width is 2.5 inches, the length can be found:
l = 3 * 2.5 + 2 = 7.5 + 2 = 9.5 inches
The area of the rectangle can be found by multiplying the length and width:
A = l * w = 9.5 * 2.5 = 23.75 square inches.

How to get the z scores?
If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
If we have
\(X \sim N(\mu, \sigma)(X is following normal distribution with mean \mu and standard deviation \sigma )\)
then it can be converted to standard normal distribution as
\(Z = \dfrac{X - \mu}{\sigma}, \\\\Z \sim N(0,1)\)
(Know the fact that in continuous distribution, probability of a single point is 0, so we can write
\(P(Z \leq z) = P(Z < z) )\)
Also, know that if we look for Z = z in z tables, the p value we get is
\(P(Z \leq z) = \rm p \: value\)

The furniture set is cheaper in Alabama, because the amount of sales tax will be lower by about $8. B. The furniture set is cheaper in Florida, because the amount of sales tax will be lower by about $10. C. The furniture set is cheaper in Alabama, because the amount of sales tax will be lower by $10. D. The furniture set costs the same in either state, because the amount of sales tax will be the same for the two locations.
Answer:
A: True
B, C and D: False
Step-by-step explanation:
We have a total sales tax for Alabama that is:
\(T_A=4.225+1.375+3=8.6\)
The total sales tax for Florida is:
\(T_F=6.5+1+1.625=9.125\)
The total sales tax is greater in Florida than in Alabama.
A. The furniture set is cheaper in Alabama, because the amount of sales tax will be lower by about $8. TRUE
The sales tax difference in this purchase can be calculated as:
\(1500(T_F-T_A)=1500\left(\dfrac{9.125-8.6}{100}\right)=1500\cdot 0.00525=7.875\approx 8\)
B. The furniture set is cheaper in Florida, because the amount of sales tax will be lower by about $10. FALSE (it is cheaper in Alabama)
C. The furniture set is cheaper in Alabama, because the amount of sales tax will be lower by $10. FALSE (the sale tax in Alabama is $129)
The amount of sales tax in Alabama is:
\(ST_A=1500\cdot T_A=1500\cdot 0.086=129\)
D. The furniture set costs the same in either state, because the amount of sales tax will be the same for the two locations. FALSE (it is not the same in both states).
