hello :
note :
an equation of the circle Center at the w(a,b) and ridus : r is :
(x-a)² +(y-b)² = r²
in this exercice : x²+y²-16x+6y+53=0
(x²-16x) +( y²+6y ) +53 = 0
(x² -2(8)x +8² - 8²) +(y² +2(3)x -3²+3² ) +53=0
(x² -2(8)x +8²) - 8² +(y² +2(3)x +3²)-3² +53=0
(x-8)² +( y+3)² = 20
the center is : w(8,-3) and ridus : r = √20

Answer:
6/8 and 12/16
Step-by-step explanation:
This is because 3/4 x 2/2 = 6/8 and 3/4 x 4/4 = 12/16
Answer:
6/8 and 9/12 are both equal to 3/4
Step-by-step explanation:
You can't simplify but you can make it bigger.
3/4 x 2/2 = 6/8
and
3/4 x 3/3 = 9/12
it should be correct because 3/3 and 2/2 are both equal to 1 which is why they are equivalent.

For which value of h will the equation below
result in an infinite number of solutions?
(3x - 8)h = -27x + 72
Answer:
h = -9
Step-by-step explanation:
Try to make the left hand side and the right hand side equal. By dividing like
h = (-27x+72)/(3x-8)
= [-9(3x-8)]/(3x-8)
= -9
When both sides are equal, you can't find the value of x as there are infinitely many solutions of x.

Circumference of the circle
Answer:
r=14/2
r=7
[tex]circumference = 2\pi {r}\\ = 2 \times \frac{22}{7} \times 7 \\ = 44[/tex]
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
Let's find the circumference of given circle ~
Circumference :
[tex] \qquad \tt \dashrightarrow \: \pi{d}^{} [/tex]
where, d = diameter
Now, let's calculate it ~
[tex] \qquad \tt \dashrightarrow \: c = 14\pi{}^{} [/tex]

if F(4)=9, the corresponding ordered pair is what
Answer:
F(5)=11.25
Step-by-step explanation:
I'm like 80% sure this is right, and I hope it helps.
First I did 9/4 which equals 2.25. and that would be F(1)
then added 2.25 to 9 which equals 11.25
multiplying 2.25 by 5 would also equal 11.25.
I did 5 because, on a number line, 5 comes after 4.
1. Ms. Rowel would like to buy a house costing $190000. She is required to make a down payment equal
to 10% of the value of the house then borrow the balance from a bank that charges interest at an annual
rate of 4.2% compounded monthly. The bank loan has to be paid o§ with equal monthly payments,
(paid at the end of each month), in 30 years. Assume that she will get the loan at the beginning of a
month and start making monthly payments on the last day of each month until the loan is paid o§
Answer:
the monthly payment would be 836.22
Step-by-step explanation:
you would find the loan amount which is 190,000 -10% of 190,000 which is 190,000 - 19,000=171,000
then you put the numbers in on a calculator which im using a spreadsheets/ excel
you need to make sure that you divide 12 for the interest and multiply 12 to the 30 years to get the monthly value of them

the graph of a line gets _____
as the value of the slope gets bigger.
A. steeper
B. longer
C. less steep
D. shorter
Answer: Less Steep
Step-by-step explanation: the graph of a line gets less steep as the value of the slope gets bigger.
The graph of the line gets steeper as the value of the slope gets bigger. Then the correct option is A.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
If the value of the slope is bigger then the line will be steeper.
Thus, the correct option is A.

What is the amplitude of the function?
Answer:
2
Step-by-step explanation:
Take the absolute value of the lowest y value.
So
[tex] | - 1| = 1[/tex]
Take the absolute value of highest y value.
[tex] |3| = 3[/tex]
Add those two together and divide by two.
[tex] \frac{1 + 3}{2} = 2[/tex]
So the amplitude is 2

Joel wants to fence off a triangular portion of his yard for his chickens. The three pieces of fencing he has measure 8 feet, 15 feet, and 20 feet long. Use this information to answer 8-9
8. Joel cut the longest piece of fencing in order to make a right triangle. Find the perimeter of Joel’s fence.
9. If it takes Joel 30 seconds to
foot of fencing, how many total minutes will it take him to install the fence?
Please help me thank you so much.
Answer:
8. Joel will not form a right triangle.
9.20 minutes
Step-by-step explanation:
8. First use theorem
Right triangle theorem
c²=a²+b²
c=20 ft
a=8ft
b=15 ft
20² =8²+15²
simplify
400= 64+225
400 does not = 289
9.
Part B)
if Joel cut the longest piece of fencing in order to make a right triangle
longest part is 17^2
a²+b²=289
c²=√289
c=17 ft
the perimeter of the fence is
a+b+c
17+8+15
perimeter is
40 ft
30 sec to install 40 ft(perimeter)
x=40*30
x=1200 seconds
x=1200/60 in minutes
x=20 minutes

Answer:
All of them
Step-by-step explanation:
To find the volume of a rectangular prism the formula is V=whl . So to find the dimensions of the box we would have to take the options that they give us and see which ones equal 80 cubic cm.
2⋅5⋅8=80, so right away we know the answer because 5⋅2=10 and 10⋅8=80
4⋅5⋅4=80, that is another possible answer because 5⋅4=20 and 20⋅4=80
10⋅4⋅2=80, yet another answer that is equivalent to 80 because 10⋅4=40 and 40⋅2= 80
So now we know that all three answers are correct and they would all work as possible dimensions for Max’s box.
Hope this helps!!
