find the circle and radius of circle at x^2 +y^2 +10x - 6y + 14=0
Answer:
see explanation
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
Given
x² + y² + 10x - 6y + 14 = 0 ( collect the x/ y terms together and subtract 14 from both sides )
x² + 10x + y² - 6y = - 14
Using the method of completing the square
add ( half the coefficient of the x/ y terms )² to both sides
x² + 2(5)x + 25 + y² + 2(- 3)y + 9 = - 14 + 25 + 9
(x + 5)² + (y - 3)² = 20 ← in standard form
with centre = (- 5, 3 ) and r = [tex]\sqrt{20}[/tex] = 2[tex]\sqrt{5}[/tex]

Solution:
We know the following rules:
Rule: If an exponent is negative, it will be in the fraction 1/nˣ.Rule: If an exponent is positive, it will be in whole number form and will multiply itself m times.Rule: if a number's exponent is 0, then the number is 1.Now, let's solve each problem.

Jackson, Monica, and Franklin are siblings. Monica's age is 12 of Jackson's age, and Franklin's age is 23 of Jackson's age. The sum of all of their ages is 36.
Which equation represents the ages, based on Jackson's age, j?
36j+12j+23j=j36 j plus 1 half j plus 2 thirds j is equal to j
j+12j+23j=36j plus 1 half j plus 2 thirds j is equal to 36
12j+23j=361 half j plus 2 thirds j is equal to 36
j+2j+23j=36
Answer:
D. j + 12j + 23j = 36Step-by-step explanation:
Given:
Jackson's age is jMonica's age is 12 of Jackson's age ⇒ Monica = 12jFranklin's age is 23 of Jackson's age ⇒ Franklin = 23jSum of all three is 36, the equation is below:
j + 12j + 23j = 36Correct choice is D

write each side with base 2
add 7 to each side
divide both sides by 2
To solve the equation [tex]2^{x-1} - 7 = 9[/tex], we add 7 to both sides make the bases the same, and equate the exponents.
What are some rules of exponents?Some common rules of exponents are
xᵃ×xᵇ = xᵃ⁺ᵇ.
xᵃ/xᵇ = xᵃ⁻ᵇ.
Addition and subtraction of exponents are only possible for the same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

The correct answer is: " [tex]j^(^-^4^)[/tex] "; or; write as: " [tex]j^{-4}[/tex] ".
_______
Step-by-step explanation:
Given: " [tex]\frac{j}{j^4* j}[/tex] " ; assuming: " [tex]j\neq 0[/tex] " ;
_______
We are asked to express the correct answer (i.e. simplying the expression in a specific manner): "as a single term, without a denominator."
_______
As such, we can cancel out the "j" in the numerator, to "1" ; and cancel out the "j" in the denominator; to "1" ; since: " j ÷ j = 1 " ;
→ And we can rewrite the expression as:
" [tex]\frac{1}{j^{4}* 1 }[/tex] " ;
= " [tex]\frac{1}{j^4}[/tex] " ;
_______
Now, note the following property of exponents:
_______
" [tex]x[/tex]⁽⁻ⁿ⁾ = [tex]\frac{1}{x^n}[/tex] " ; {" [tex]x\neq 0[/tex] "} ;
_______
Likewise:
" [tex]\frac{1}{j^4}[/tex] ⇔ " [tex]j^(^-^4^)[/tex] " ; which is the correct answer:
→ " [tex]\frac{1}{j^4} = j^{-4}[/tex] " .

Three friends decide to rent an apartment and split the cost evenly. They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. If rent is $650 per month, how much was the security deposit? a. $10 b. $207 c. $620 d. $1,270 Please select the best answer from the choices provided A B C D.
Total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.
What is monthly payment?The monthly payment is the amount which is required to pay each month to pay off the borrowed principal amount or the rent of a service charged monthly.
The rent of the apartment is $650 per month. The rent of the two months (first and last) is,
[tex]M=2\times650\\M=1300[/tex]
This rent is paid by three friends. Thus, the amount which is paid by an individual friend is,
[tex]P=\dfrac{1300}{3}\\P=433.33[/tex]
They each paid $640 towards the total move in cost of first and last month's rent and a security deposit. Therefore,
[tex]P=640-433P=206.67[/tex]
Thus, $206.67 is paid by each of them towards security deposits. The total amount of security deposit, deposited by 3 of them, is,
[tex]SD=206.67\times3\\SD=620.01[/tex]
Hence, total amount of security deposit, deposited by three friends after paying the rent is $620.01. Option C is the correct option.

scalene quadrilateral
Step-by-step explanation:
When calculations are repetitive, it is reasonable to let a spreadsheet do them.
FG: slope: -4/5, length: √41 ≈ 6.40
GH: slope: -5, length: √26 ≈ 5.10
HI: slope: -1, length: 3√2 ≈ 4.24
IF: slope: 4, length: √17 ≈ 4.12
All of the segments are different lengths, and none of them are parallel or perpendicular. The figure is a scalene quadrilateral.
__
As you know, the slope is calculated from ...
m = (y2 -y1)/(x2 -x1)
and the length is calculated from ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
_____
In the attached spreadsheet, the slope and length are calculated from the point below. That is, the values on the line for F are for segment FG.

Torrance is buying presents for members of his family. He wants to spend $10 less on his brother than he spends on his sister, and six dollars more than twice the amount he spends on his sister on his mother. If Torrance has $100 to spend, how much does he intend to spend on his brother?
Let x = the $ Torrance spends on his sister
Answer:
Torrance spends 16$ on his brother
Step-by-step explanation:
You have 100$
So, we have
x (brother) + x (sister) + x (mother) = 100
But, since 10$ less will be spent on the sister than the brother, it becomes (x - 10) and twice + 6$ is spent on the mom, it also becomes (2x + 6)
Our equation then becomes
(x - 10) + x + (2x + 6) = 100
X will end up equaling 26. This is how much is spent on the sister.
(x - 10) will be substituted for (26 - 10), which equals 16.
