identify the center and the radius of a circle with equation (x-4)^2+(y+2)^2=9

Answer:

The answer to this is 34 minutes and 50 seconds.

Step-by-step explanation:

First, I multiplied 23 x 2 = 46 because I wanted to see how much minutes it could be in 20 minutes.

Then, I got the answer by getting the median.

23 - 46

the median of that is 34.5. Therefore, the expected time for 15 laps is 34 minutes and 50 seconds.

Hope this Helped!!!!

Answer:

34.5 Is the answer or 34 minutes and 5 seconds.

Step-by-step explanation:

1) Set a Proportion Minutes on top over laps

23/10 = x/15

2) cross Multiply

10 times x = 10x

23 times 15 = 345

3) Solve for X (x is the amount of minutes for 15 laps)

345 = 10x

Divide 10 on both sides

345/10= 34.5

use the compass and find the midpoints of each side of the triangle. the use the ruler and find the radius and connect it to the vertex ISO - trigonometric diameter. Mark the angles as 90 deg corresponding to the rays formed by the radii. simple :)

Answer: PLATO ANSWER

Step-by-step explanation:

Step 1: Place the compass needle on vertex A, adjust the width of the compass to a medium setting, and draw one arc on line segment AB and one on line segment AC.

Step 2: Place the compass needle on the point where the arc intersects line segment AB and draw an arc inside the triangle. Without changing the compass setting, place the compass needle on the point where the arc intersects line segment AC; draw another arc intersecting the arc already inside the triangle. Label the point of intersection P.

Step 3: Draw line segment AP. This is the angle bisector of angle A.

Step 4: Place the compass needle on vertex C, adjust its width to a medium setting, and draw arcs intersecting line segment BC and line segment AC.

Step 5: Place the compass needle on the point where the arc intersects line segment BC, and draw an arc inside the triangle. Without changing its setting, place the compass on the point where the arc intersects line segment AC; draw another arc intersecting the arc already inside the triangle. Label the point of intersection Q.

Step 6: Draw line segment CQ. This is the angle bisector of angle C.

Step 7: Label the intersection of the angle bisectors M. This is the center of the inscribed circle.

Step 8: Place the compass needle on M, and draw two arcs on line segment BC.

Step 9: Place the compass needle on one of the points where an arc intersects line segment BC, and draw an arc outside the triangle; repeat from the point where the other arc intersects line segment BC to create two intersecting arcs outside the triangle. Draw a line from M passing through the point of intersection outside the triangle. This is a perpendicular line from M to line segment BC. Mark the point where the line intersects line segment BC, and label it N.

Step 10: Place the compass needle on M, set its width to N, and draw a circle. This is the inscribed circle of triangle ABC.

Answer: 4=y

Step-by-step explanation:

6(7 -3y)+6(y+1)

42-18y+6y+6

48-12y

48/12=4

12y/12=y

4=y

The student's algebraic expression simplifies to 48 - 12y.

The question involves simplifying an algebraic expression. Let's solve it step by step:

Distribute the 6 to each term inside the first parentheses: 6(7) / (- 6(3y)).

Do the same for the second parentheses: 6(y) + 6(1).

Combine like terms by adding or subtracting the coefficients.

Let's simplify the expression now:

6(7) - 6(3y) + 6(y) + 6(1).

42 - 18y + 6y + 6.

Combine the terms with y: -18y + 6y = -12y.

The final simplified expression is 42 - 12y + 6.

Combine the constant terms: 42 + 6 = 48.

The final answer is 48 - 12y.

Answer: [tex]\dfrac{2}{13}[/tex]

Step-by-step explanation:

Given : A bag contains 6 red balls, 4 green balls, and 3 blue balls.

Total balls = 6+4+3=13

Probability of drawing first ball as green :

[tex]P(G)=\dfrac{\text{Number of green balls}}{\text{Total balls}}\\\\=\dfrac{4}{13}[/tex]

If the first ball will be green, then the total balls left in bag = 13-1=12 and number of red balls remains the same.

Now, The conditional probability of drawing a red ball given that first ball was green :-

[tex]P(R|G)=\dfrac{\text{Number of red balls}}{\text{Total balls left}}\\\\=\dfrac{6}{12}=\dfrac{1}{2}[/tex]

Now,  the probability that the first ball will be green and the second will be red will be :-

[tex]P(G\cap R)=P(G|R)\times P(G)\\\\=\dfrac{4}{13}\times\dfrac{1}{2}=\dfrac{2}{13}[/tex]

Hence, the required probability = [tex]\dfrac{2}{13}[/tex]

8.25 rounded off to the nearest whole number is 8, because the digit after the decimal point (2) is less than 5, which implies that we do not increase the whole number part.

To round off 8.25 to the nearest whole number, we look at the digit to the right of the decimal point, which is 2. Since this digit is less than 5, we keep the digit before the decimal point as it is. Therefore, 8.25 rounded off to the nearest whole number is 8.

When rounding numbers, such as rounding off 0.028675 to 0.0287 or 92.85 to 92.8, a key rule to remember is that if the dropped digit is greater than or equal to 5, you round up; if less, you round down. Applying this principle, we see that because 2 is less than 5, 8.25 rounds down, leaving us with 8 as the rounded result.

okay so I'm going to be honest I'm not fully sure if my answer is correct but I think that you must add it up and they answer that you will get is 64 because remember 4 + 2 equals 6 and 4 + 0 equal 4

Answer:

[tex]40\pi\text{ cubic feet}[/tex]

Step-by-step explanation:

Given,

The diameter of the pipe = 24 inches,

⇒ The diameter of the section = 24 inches

And, it is laid in 40 foot section,

So, the height of each section = 40 feet,

Since, the shape of a pipe is cylindrical,

The volume of a cylinder is,

[tex]V=\pi (r)^2 h[/tex]

Where, r is the radius,

h is its height,

Here, r = [tex]\frac{24}{2}[/tex] = 12 inches = 1 feet,

Also, h = 40 foot,

Thus, the quantity of water hold by the section = Volume of the section

[tex]=\pi (1)^2(40)[/tex]

For the expression "X is 110% of 10," X is equal to 11.

For the expression "y% of 50 is 3.5," the value of y is 7.

From the information given, we can solve for both x and y:

1. Finding x:

"X is 110% of 10" means that x is equal to 110% multiplied by 10.

110% can be written as a decimal by dividing by 100: 110/100 = 1.1

Therefore, x = 1.1 * 10 = 11.

2. Finding y:

"y% of 50 is 3.5" means that y% multiplied by 50 is equal to 3.5.

To solve for y%, we can rearrange the equation: y% = 3.5 / 50.

To express y as a percentage, we can multiply by 100: y = (3.5 / 50) * 100 = 7.

Complete question:

Calculate the percentage: X is 110% of 10, y% of 50 is 3.5

Final answer:

We calculated x by determining that it's 110% of 10, which results in x being 11. Then, we solved for y by understanding that y% of 50 equals 3.5, leading to the conclusion that y is 7.

Explanation:

To solve for x, we consider that it is 110% of 10. To convert a percentage into a decimal, we divide by 100, so 110% becomes 1.10. Therefore, x = 1.10 × 10. After multiplying, we get x = 11.

For the second part, we have y% of 50 is 3.5. The equation can be represented as (y/100) × 50 = 3.5. To find y, we divide both sides by 50 and then multiply by 100 to get y = (3.5 × 100) / 50. Solving for y, we find y = 7.

Answer:

an = 2 - 3n ⇒ The third answer

Step-by-step explanation:

∵ a1 = -1

∵ a2 = -4

∵ a3 = -7

∵ a2 - a1 = -4 - -1 = -3

∵ a3 - a2 = -7 - -4 = -3

∴ It is an arithmetic sequence with

  1st term = -1 and constant difference = -3

∵ The rule of any arithmetic is: an = a + (n - 1)d

∵ a = -1 and d = -3

∴ an = -1 + (n - 1)(-3)

∴ an = -1 - 3n + 3

∴ an = 2 - 3n ⇒ The third answer

Now let's find the values of a b and c.

Use the standard form of the quadratic equation.

ax^2+bx+c = 0

Using this we can find the values of a b and c.

a = 1

b = 1

c = -30-8

c = -38

Now plug in the values.

We get,

5.68 and -6.68

Answer:

-6.18

Step-by-step explanation:

First we need to get this into an equation form that will allow us to factor it.

x^2+cx+c

Make one side of the equation equal to zero.

x^2+x-30=8  

-8      -8

x^2+x-38=0

We can't use the zero product property because it is impossible to multiply numbers to get -38 and the same numbers at to 1. Therefore, let's use the quadratic formula. y=-b√b^2-4(a)(c) /2a

Then, identify your a, b and c. A=your squared number, B= your number neing multiplied by a varable (1x or x), and C is your whole number.

a=1

b=1

c=-38

y=-1√1^2-4(1)(-38) /2(1)

Simplify

y=-1√1+152 /2

y=-1√153 /2

y=-3√17/2

Decimal form: −6.18465843

About -6.18 is your answer.

x^2-10x+(-5)^2=-29+(-5)^2

Then, simplify the equation:

x^2-10x+25=-4

Next, factor into (x-5)^2 which is:

(x-5)^2= -4

Finally, solve for X:

x=5 +/- 2i

x2+10×+29=0
