Answer:
[tex](x-1)^{2}+(y-3)^{2} = 5[/tex]
Step-by-step explanation:
Given the general equation of a circle represented as:
[tex](x-a)^{2}+(y-b)^{2} = r^{2}[/tex] where:
(a, b) is the centre of the circle and r is the radius
Given the centre located a (1,3), to get the radius we will take the distance between the centre point of the circle the the point that lies on its circumference i.e (0,1).
Using the formula for calculating thee distance between 2 points, we have:
[tex]r = \sqrt{ (x2-x1)^{2}+(y2-y1)^{2}}[/tex]
x1 = 1, y1 = 3, x2 = 0, y2 = 1
[tex]r = \sqrt{ (0-1)^{2}+(1-3)^{2}}\\r=\sqrt{1^{2} +(-2)^{2}}\\r=\sqrt{1+4}\\r=\sqrt{5}[/tex]
Substituting this values of the centre and radius of the circle into the general equation of a circle we have:
[tex](x-1)^{2}+(y-3)^{2} = (\sqrt{5}) ^{2}\\(x-1)^{2}+(y-3)^{2} = 5[/tex]
This gives the required equation of the circle.
What is the volume of a cylinder with base radius 333 and height 888?
Either enter an exact answer in terms of \piπpi or use 3.143.143, point, 14 for \piπpi and enter your answer as a decimal.
Answer:
V≈3.09×108
Step-by-step explanation:
Shape: Cylinder
Solved for volume
Radius: 333
Height: 888
Formula: Radius, Height
Exact answer: V≈3.09×108
Hope this helps.
The volume of the cylinder is = 98,469,432π
Calculation of volume of cylinderThe radius of the cylinder = 333
The height of the cylinder = 888
Therefore the volume is = ?
The formula for the volume of cylinder = πr²h
V = π× 333² × 888
V = π × 110,889× 888
V = 98,469,432π
Therefore, the volume of the cylinder is = 98,469,432π

Answer:
number five: 37.065 number six 241
Step-by-step explanation:
FOR NUMBER FIVE:
so for the rectangles, the formula is L * W. L for length W for width
so 5×3 = 15. and there are 2 rectangles with the same measurment so its
15 + 15 which is 30 (for both rectangles)
and for the circle formula its pi r^2 where pi is 3.14 and r is radius
so 3.14 × 3^2 = 28.26. but since its a quarter of a circle, divide it by four which is 7.065.
so 30 + 7.065 = 37.065
FOR NUMBER SIX:
the area of a triangle formula is b * h ÷ 2 where b is base and h is height
so its 22 * 8 / 2 = 88
and for the trapezoid the formula is [tex]\frac{a+b}{2} h[/tex] where a and b are the bases and h is height
so its[tex]\frac{12+22}{2} *9[/tex] = 153
88+153= 241

The central angle of an arc measures 120° The radius of the circle measures 3 cm what is the area of the sector to the nearest hundredth of a square centimeter
Answer:
The area of the sector should be 9.42[tex]cm^2[/tex] .
Step-by-step explanation:
-The formula for finding the area of a sector:
[tex]A = \frac{Arc}{360} \pi r^2[/tex]
-Next use the arc measure and the radius in order to solve and get the answer:
[tex]A = \frac{120\textdegree}{360\textdegree}\pi 3^2[/tex]
-Solve:
[tex]A = \frac{120\textdegree}{360\textdegree}\pi 3^2[/tex]
[tex]A = \frac{120\textdegree}{360\textdegree}\pi \times3^2[/tex]
[tex]A = \frac{1}{3} \pi \times 3^2[/tex]
[tex]A = \frac{1}{3} \pi \times 9[/tex]
[tex]A = 3\pi \approx 9.424[/tex]
-Round to the nearest hundredth:
[tex]A \approx 9.42[/tex]

Calculators cannot display repeating decimals. Calculators always round. Yuri's calculator displays decimals to 5 places. He uses his calculator to find the decimal equivalent for each of the fractions below. For each number, choose what his calculator will display as the decimal equivalent. Then choose whether or not this is the exact decimal equivalent.
1/9
Calculator display for 1/9:
Is this the exact decimal equivalent?
7/9
Calculator display for 7/9:
Is this the exact decimal equivalent?
9/10
Calculator display for 9/10:
Is this the exact decimal equivalent?
1/9 = 0.111111111..., No
7/9 = 0.777777...8, No
9/10 = 0.9, Yes
Dividing by a non-factor of 9 by 9 will always result in an infinite decimal, similar to dividing a non-factor of 3 by 3 or a non-factor of 7 by 7.
However, dividing a number by 10 will simply move the decimal one value to the right, so 9.0 divided by 10 is 0.90.

Becca sells bracelets for $9 each. She has to pay $4.35 for the materials for each bracelet. How much money does she make from each bracelet after she pays herself back for the materials? How much money does becca make from the sale of 15 bracelets?
i am marking brainiest
Answer:
$4.65$69.75Step-by-step explanation:
How much money she makes from each bracelet:
9-4.35=$4.65
How much money she makes from the 15 bracelets:
4.65 x 15= $69.75
Answer:
Part 1: 4.65
Part 2: 69.75
Step-by-step explanation:
The first question is "How much money does she make from each bracelet after she pays herself back for the materials?"
To answer that, we must find how much she is selling them for ($9) and subtract the cost of the materials from it ($4.35), which equals 4.65
The second question is How much money does becca make from the sale of 15 bracelets?
In other words, they are only asking for the profit made which means they don't want the materials used cost included. So we can use the answer from before and multiply by 15, so 4.65*15=69.75.
Hope that makes it clear, and good luck with studies :)

You spin the spinner twice.
What is the probability of landing on a 3 and then landing on a 2?
Simplify your answer and write it as a fraction or whole number.
Answer: 1/9
Step-by-step explanation:
You have 3 possible options. The probablility of the spinner landing on 3 is 1/3. The probability of it landing on 2 is also 1/3. For them to happen together, you multiply them. 1/3 * 1/3 = 1/9.
The probability of landing on a 3 and then landing on a 2 is,
⇒ 1/9
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Given that;
You spin the spinner twice.
Now, The probability of the spinner landing on 3 is,
⇒ 1/3.
And, The probability of it landing on 2 is,
⇒ 1/3.
Hence, The probability of landing on a 3 and then landing on a 2 is,
⇒ 1/3 × 1/3
⇒ 1/9.

Answer:

Step-by-step explanation:
Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.
33x-33= 33x + 25
33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.
33x+33=33x+25
33x+8= 33x nope no solution
33x+25=33x+25
33x = 33x both sides identical so there is a solution
33x-25 = 33x +25
33x= 33x+50

Which expression represents the area of the base of the cone? A cone with diameter 12 inches, height 8 inches, and slant height 10 inches. B = pi r squared (pi) (5 squared) (pi) (6 squared) (pi) (10 squared) (pi) (12 squared)
Answer: (pi) (6 squared)
Step-by-step explanation:
Hi, the base area of a cone is a circle, so, to answer this question we have to apply the next formula:
Area of a circle: (pi) radius^2
The diameter (d) of a circle is equal to: 2 radius
So:
D = 2r
Replacing with the value given:
12 =2r
12/2=r
radius= 6 inches
Back with the Area formula:
A = (pi) 6^2

Answer: 25 + 3n
Step-by-step explanation:
Hi, the answer is lacking the last part:
Write an expression for the amount of money he makes this week.
So, to answer this we have to write an expression:
The fixed amount that he earns per week (25) plus the product of the amount he earns per subscription (3) and the number of subscriptions sold (n) , must be equal to his weekly earnings.
Mathematically speaking:
25 + 3n
