Answer:
( x + 2 )² + ( y - 1 )² = 25
Step-by-step explanation:
Circle equation - ( x - h )² + ( y - k )² = r²
Important notes:
(h,k) = center
r = radius
The first step would be to find the center
( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )
Like stated before ( h , k ) = center point
* replace center point with (-2,1) *
( h , k ) = ( -2 , 1 )
h = -2
k = 1
* plug in the h and k values into the circle equation *
now we have ( x - ( -2) )² + ( y - 1 )²
Now to find the radius
We can find the radius by using the distance formula with the center point and any point on the circle's outline
The point chosen can vary but i chose (3,1)
Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius
3 - (-2)
the two negative signs cancel out
3 + 2 = 5
So the radius equals 5
* plug in the value of the radius into the equation *
Now we have
( x - (-2) )² + ( y - 1 )² = 5²
our final step is to simplify
- (-2) the two negative signs cancel out and it turns into +2
5² = 25
Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

Find the ordered pair that is a member of both -2x + 6y = 34 and
2x + 2y = 14 or indicate if it does not exist or there are infinite
possibilities.
Answers
Answer:
(1, 6) is the solution
Step-by-step explanation:
-2x + 6y = 34
2x + 2y = 14; divide by 2
x + y = 7; subtract x
y = 7 - x
let's substitute y with 7 - x in first equation
-2x + 6*(7 - x) = 34; expand multiplication
-2x + 6*7 - 6*x = 34; group
-8x + 42 = 34; subtract 42
-8x = 34 - 42 = -8; divide by -8
x = 1
y = 7 - 1 = 6
It is the only solution, as we've arrived at exact numbers.
David has a monthly after-tax income of $ 1430.15 1430.15 . He will be using the companies health insurance plan which costs $ 63 63 a monthand the retirement option which takes 7 7 % of his after tax income. Calculate David's Monthly Take-Home pay.
Answers
Answer:
$ 1267.
Step-by-step explanation:
Given :
David's monthly income after tax = $ 1430.15
His health insurance cost him in a month = $ 63
Percent deducted from his income after tax for his retirement option is = 7%
Therefore money left after retirement option deduction is :
$ 1430.15 - 7% of $ 1430.15
= 1430.15 - 100.11
= $ 1330.04
= $ 1330 (aprrox)
Money deducted from this amount for his health insurance plan
= $ 1330 - $ 63
= $ 1267
Therefore, David's monthly take home pay is $ 1267.

Answer and Step-by-step explanation:
When we take a look at the graph, we can see that at around 1 gallon, which would be halfway between 0 and 2, the line is underneath $5.
That means we can eliminate any number that is or above $5.
That leaves us with answer choices A and C.
Let's go to a point that is easily readable. Point (4, 15) is readable, and we can use this to find the price per gallon.
Divide 15 by 4. We get 3.75 as the result.
This means that the answer choice is:
C. The cost of gas is $3.75 per gallon.

Cyber Monday Shopping A survey of 1000 U.S. adults found that 33% of people said that they would get no work done on Cyber Monday since they would spend all day shopping online. Find the 95% confidence interval of the true proportion.
Answer:
(0.301 ; 0.359)
Step-by-step explanation:
Sample size, n = 1000
Phat = 0.33
(1 - phat) = 1 - 0.33 = 0.67
Zcritical at 95% = 1.96
Confidence interval :
Phat ± margin of error
Margin of Error = Zcritical * sqrt[(phat(1 - phat)) /n]
Margin of Error = 1.96 * sqrt[(0.33 * 0.67) / 1000]
Margin of Error = 1.96 * 0.0148694
Margin of Error = 0.0291440
Lower boundary = (0.33 - 0.0291440) = 0.300856
Upper boundary = (0.33 + 0.0291440) = 0.359144

A circle is drawn inside a square so its circumference touches each of the four sides of the square. If the area of the circle is 99.2cm2 calculate the length of the sides of the square.
Answers
Answer:
The length of the sides of the square is approximately 11.239 centimeters.
Step-by-step explanation:
Since the circle is inscribed in the square, the length of each side of the square ([tex]l[/tex]), in centimeters, is equal to the length of the diameter of the circle ([tex]D[/tex]), in centimeters. The area of the circle ([tex]A_{c}[/tex]), in square centimeters:
[tex]A_{c} = \frac{\pi\cdot D^{2}}{4}[/tex] (1)
Where [tex]D[/tex] is the diameter of the circle, in centimeters.
If we know that [tex]A_{c} = 99.2\,cm^{2}[/tex], then the length of the sides of the square is:
[tex]D = \sqrt{\frac{4\cdot A_{c}}{\pi} }[/tex]
[tex]l = D \approx 11.239\,cm[/tex]
The length of the sides of the square is approximately 11.239 centimeters.

[tex] x = 45 \ \& \ y = 5 [/tex]
Step-by-step explanation:
The system of linear equations in two variables is ,
[tex]\begin{cases} x = 9y \cdots (i)\\ x - 5y = 20\cdots (ii) \end{cases}[/tex]
We can easily solve out this Question using substitution method . For that , substituting x = 9y from equation (i) to equation (ii) , we have ,
[tex]\implies x - 5y = 20 \\\\\implies 9y - 5y = 20 \\\\\implies 4y = 20 \\\\\implies y =\dfrac{20}{4}\\\\\implies\boxed{\boxed{ y = 5 }}[/tex]
Substituting this value in (i) ,
[tex]\implies x = 9y \\\\\implies x = 9\times 5 \\\\\implies \boxed{\boxed{ x = 45 }}[/tex]
Answer: (45,5)
Step-by-step explanation:
You're given what x equals: 9y. Substitute that into the equation x - 5y = 20. Your equation should look like this: 9y - 5y = 20. From there, solve for y. 9y subtracted by 5y is 4y. Then, solve 4y = 20. Divide both sides of the equation by 4. The result is y = 5. We now know the y-coordinate in the ordered pair. Substitute this y-value into the first equation: x = 9y. 9(5) = 45. x = 45.
Plug these two values into the ordered pair (x,y).
