Answer:
(x-9)^2 + (y-9)^2 = 81
Step-by-step explanation:
Step-by-step explanation:Equation of a circle
( x - h )^2 + ( y - k )^2 = r^2
Your graph - the circle intersects the x-axis at (9 , -9)
- the circle intersects the y-axis at (9 , -9)
h = the number on the x axis intersected by the circle.
k = the number on the y axis intersected by the circle.
r = radius of the circle measured starting from the origin.
plug these in:
( x - h )^2 + ( y - k )^2 = r^2.
(x - 9)^2 + (y - 9)^2 = 9^2
(x-9)^2 + (y-9)^2 = 81
We are given with a circle and we need to find the equation of the circle , but first let's recall that , the equation of a circle with radius 'r' and centre at (h,k) is given by [tex]{\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}[/tex]
Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here (h,k) = (0,0) .Which means that the centre is located at the point whose coordinates are (0,0) which is also known as origin . Now , finding the equation of the circle :-
[tex]{:\implies \quad \sf (x-0)^{2}+(y-0)^{2}=(9)^{2}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{x^{2}+y^{2}=81}}}[/tex]
This is the required equation of Circle

Find the radius of a circle whose center is (0,3) and a y-intercept of (0,7)
The radius of the circle is the distance between the center and the y-intercept.
The radius of the circle is 4 units
How to determine the radiusThe given parameters are:
Center = (0,3)
Y-intercept = (0,7)
The radius is calculated as:
[tex]r = \sqrt{(0 - 0)^2 + (3 - 7)^2}[/tex]
Evaluate
[tex]r = \sqrt{16}[/tex]
Solve
[tex]r =4[/tex]
Hence, the radius of the circle is 4 units

A cooler has a 60-L capacity. Its internal length is 60 cm and its internal width is 35 cm. Determine the internal height and the internal surface area of the cooler.
Hint 1 cm=1 ml
Answer:
Internal height is approximately 28.5714285714286 cm
Internal surface area is roughly 9628.57142857143 square cm
Round the values however you need to
Step-by-step explanation:
Work Shown:
1 L = 1000 mL
1 L = 1000 cm^3
60 L = 60,000 cm^3 (multiply both sides by 60)
The cooler has volume of 60,000 cubic cm. Let V = 60000
Assuming the cooler is a rectangular prism (aka a block), then we can say
volume = length*width*height
V = L*W*H
60000 = 60*35*H
60000 = 2100H
2100H = 60000
H = 60000/2100
H = 28.5714285714286 which is approximate
And the surface area (SA) is
SA = 2*(LW + LH + WH)
SA = 2*(60*35 + 60*28.5714285714286 + 35*28.5714285714286)
SA = 9628.57142857143 which is also approximate
Units for the surface area are in square centimeters.

How many acres did Ms. Green plant with potatoes?
Answer: Reduce the expression, if possible, by cancelling the common factors.
Exact Form:
1/40
Decimal Form: 0.025
Step-by-step explanation:
Answer:
[tex]22 \frac12[/tex] acres
Step-by-step explanation:
We need to find 3/4 of 30.
Method 1
30 by 3/4:
[tex]\implies 30 \times \dfrac34=\dfrac{30}{1}\times \dfrac34= \dfrac{30\times3}{1 \times4}=\dfrac{90}{4}=22 \frac12[/tex]
Method 2
Divide 30 by 4: 30 ÷ 4 = [tex]\frac{15}{2}[/tex]
Multiply the result by 3: [tex]\frac{15}{2}[/tex] x 3 = [tex]\frac{45}{2}[/tex] = [tex]22 \frac12[/tex]

A girl 164 cm tall stands 366 cm from a lamp post at night. Her shadow from the light is 83 cm long. How high is the lamp post?
Answer:
Step-by-step explanation:
person height/shadow length = lamp height / shadow length lamp
Person height = 164 cm
shadow length = 83
lamp height = x
lamp shadow length = 366 + 83 = 449
164/83 = x/449 Cross Multiiply
83x = 164 * 449 Combine Right
83x = 73636 Divide by 83
x = 73636/83
x = 887.18

2/7 of the people watching a football game are children. 3/8 of the children are girls.
(a) What fraction of the people watching the football game are girls?
(b) What fraction of the people watching the football game are boys?
(C) What fraction of the people watching the football game are not children?
Answer:
(a) 3/28
(b) 5/28
(c) 5/7
Step-by-step explanation:
(a) To find 3/8 ths of 2/7, multiply the fractions:
[tex]\implies \dfrac38 \textsf{ of } \dfrac27=\dfrac27 \times \dfrac38=\dfrac{2 \times3}{7 \times8}=\dfrac{6}{56}=\dfrac{3}{28}[/tex]
(b) The sum of the probabilities of all possible outcomes is 1.
Therefore, if 3/8 of the children are girls, then 1 - 3/8 are boys:
[tex]\implies 1-\dfrac38=\dfrac88-\dfrac38=\dfrac{8-3}{8}=\dfrac58 \textsf{ of children are boys}[/tex]
So again, multiply 5/8 by 2/7 to find 5/8ths of 2/7:
[tex]\implies \dfrac58 \textsf{ of } \dfrac27=\dfrac27 \times \dfrac58=\dfrac{2 \times5}{7 \times8}=\dfrac{10}{56}=\dfrac{5}{28}[/tex]
(c) The sum of the probabilities of all possible outcomes is 1.
Therefore, if 2/7 of the people watching the football game are children, then 1 - 2/7 are not children:
[tex]\implies 1-\dfrac27=\dfrac77-\dfrac27=\dfrac{7-2}{7}=\dfrac57 \textsf{ of people watching the football are NOT children}[/tex]
Used books cost $2. 25 each. Which expression represents the total number of books that can be purchased for $10?
Answer:
x is the number of books
2.25x≤10
Hope This Helps!!!
The expression representing the total number of books that can be purchased for $10 is [10/2.25], a step function.
What is a step function?A Step function or the greatest integer function is of the form f(x) = [x] gives us the value of f(x) as the first integer less than or equal to x, that is, x-1≤ f(x) ≤ x, f(x) ∈ I.
How do we solve the given question?We are informed that the cost of each book is $2.2.5, and the total money with the person is $10.
∴ The total number of books that can be purchased for $10, will e a step function, as the number of books needs to be an integer, with the total amount in hand divided by the cost of each book.
∴ The total number of books that can be purchased for $10 = [10/2.25].

Factors of 18:
1, 2, 3, 6, 9, 18
Factors of 30:
1, 2, 3, 5, 6, 10, 15, 30
GCF of 18 and 30: 6
18h+30k = 6(3h+5k)
Check your answer:
6(3h+5k)
6(3h) + 6(5k)
18h + 30k
Hope this helps!
Answer:
Step-by-step explanation:
To factor this, we can factor both variables and then get a multiplier outside the parentheses and the new variables inside. (Sorry if it’s confusing)
18h = 2*3*3*h
30k = 2*3*5*k
Both have 2*3, which is 6. This will be the multiplier. To get the new variables, divide the old variables by 6.
18h/6 = 3h
30k/6 = 5k
The signs should not change.
6(3h+5k)

Area between two concentric circles
Answer: 215π
Step-by-step explanation:
If you think of the entire thing as two circles, it makes the problem a lot easier. If we were to find the area of the white "circle" and subtract it from the blue "circle", we would get the area of the ring. First, use the outer radius to find the area of this circle:
[tex]Area=\pi r^2[/tex]
[tex]Area=\pi (24)^2=576\pi[/tex]
Now find the area of the inner circle:
[tex]Area=\pi r^2[/tex]
[tex]Area=\pi (19)^2=361\pi[/tex]
Subtract the area of the inner circle from the area of the outer circle:
[tex]576\pi -361\pi =215\pi[/tex]

Question 5 options:
y=−3x+2
y=1/2x+3
y=3
y=x+3
Answer: y=x+3
Step-by-step explanation: First, I drew a line that equally divided the two points. It looks like R was moved 4 points tot he right and then 4 points down, so draw the line in that direction.
Then I picked 2 points on the line, where the line intersects the graph.
I chose (-3,0) and (2,5) and used those to solve for the equation of the line.
Gradient=> [tex]\frac{y2-y1}{x2-x1} = \frac{5-0}{2-(-3)}=\frac{5}{5}=1[/tex]
y = mx+c => 5 = 1(2) +c
c= 5-2 =3
Therefore, equation of the line is y = 1(x) + 3 => y = x + 3
