Answer:

[tex](x - 6)^2 + y^2 = 25[/tex]

Step-by-step explanation:

The standard form of a circle is [tex](x - x_1)^2 + (y - y_1)^2 = \text{R}^2[/tex], where [tex](x_1\text{, }y_1)[/tex] is the center point of the circle, and [tex]\text{R}[/tex] is the circle's radius.

We're given the center of our circle is (6, 0) and its radius is 5, therefore, the circle's equation in standard form is:

[tex](x - 6)^2 + (y - 0)^2 = 5^2\\\to (x - 6)^2 + y^2 = 25[/tex]

Answer:

(x - 6)² + y² = 25

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² +(y - h)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (6, 0 ) and r = 5 , then

(x - 6)² + (y - 0)² = 5² , that is

(x - 6)² + y² = 25

The perimeter of the triangle is 64 when the triangle is ZTW.

Given that,

In the picture we have a triangle ZWT.

The U and V are mid points of WT and Y and X are midpoints of ZW.

We have to find the perimeter of the triangle.

We get the sides

ZT=22

We have,

TU/ZY= UV/YX= VW/XW  (Thales theorem)

6/8= a/12= 3/b

3/4=a/12= 3/b

Take,

3/4=a/12

a=3/4×12

a=3×3

a=9

Take,

3/4=3/b

b=3×4/3

b=4

The side TW=6+9+3=18

The side ZW=8+12+4=24

The perimeter of the triangle is sum of the sides.

The perimeter of the triangle=ZT+ZW+TW

The perimeter of the triangle= 22+24+18

The perimeter of the triangle= 64

Therefore, The perimeter of the triangle is 64 when the triangle is ZTW.

5.  (6 hours)/(1 day)

6.  (8 quarts)/(1 container)

Step-by-step explanation:

5.  The number line shows both hours and days.  It does not indicate why the relationship exists.  Perhaps the hours are the ones worked in a day.  What’s important is whether the relationship between the two is the same for all data pairs.  E.g., 12/2 = 6; 36/6 = 6; 60/6 - 5, and so forth.  They are all the same ratio, or rate: (6 hours)/(1 day)

6.  The number line shows both quarts and containers.  The  relationship between the two is the same for all data pairs.  E.g., 8/5,  16/10 or 8/5; 24/15 or 8/5; 32/20 or 8/5, and 40/25 or 8/5.   They are all the same ratio, or rate: (8 quarts)/(1 container).

Answer:

152°

Step-by-step explanation:

the sum of the exterior angles of a polygon = 360°

let x be the measure of the fifth exterior angle , then

92° + 73° + 63° + 104° + x = 360°

332° + x = 360° ( subtract 332° from both sides )

x = 28°

then

interior angle + exterior angle = 180° , that is

interior angle + 28° = 180° ( subtract 28° from both sides )

interior angle = 152°

the exterior angles of a polygon is 360°

92 + 73 + 63 + 104 = 332

360 - 332 = 28° is the measure of the fifth interior angle.

The volume of the balloon after the addition of the extra gas is 11.87 liters

The initial volume of the balloon = 5.29 liters

Initial quantity of argon in the balloon = 2.51 mole

Here we have to use the unitary method

The volume of the 1 mole of argon = The initial weight  of the balloon / Initial quantity of argon in the balloon

Substitute the values in the equation

The volume of the 1 mole of argon = 5.29 / 2.51

= 2.11 liters

Additional argon added = 2.51 mole

Total quantity of argon = 2.51 + 3.13

= 5.64 mole

The volume of the 5.64 mole of argon = 5.64 × 2.11

= 11.87 liters

Hence, the volume of the balloon after the addition of the extra gas is 11.87 liters

The angles shown are vertical angles

Vertical angles are congruent (equal to each other)

This means that 8x + 36 = 5x + 60

Using this equation we can solve for x

8x + 36 = 5x + 60  

==> subtract 36 from both sides

8x = 5x + 24

==> subtract 5x from both sides

3x = 24

==> divide both sides by 3

x = 8

Answer:

[tex]\huge\boxed{\sf x = 8}[/tex]

Step-by-step explanation:

8x + 36 = 5x + 60 (Vertically opposite angles are equal)

Subtract 5x to both sides

8x - 5x + 36 = 60

3x + 36 = 60

Subtract 36 to both sides

3x = 60 - 36

3x = 24

Divide 3 to both sides

We can use proportional reasoning to describe that when the two quantities multiplied equal a constant.

Hence, Option (C) is correct.

What is a proportion?

A proportion is a type of ratio in which the denominator also contains the numerator. For example, the proportion of male deaths would be deaths to males divided by deaths to males plus deaths to females (i.e. the total population).

Let 'x' be the numerator and 'y' be denominator,

then one ratio is 'x/y' and its reciprocal by using the proportion would be 'y/x'

and then their multiplication will be

                               [tex]=\frac{x}{y}*\frac{y}{x} \\\\\=1[/tex]

Multiplication gave us '1', which is a constant.

Hence option (C) is the correct answer.

The probability of a student playing a sport but not playing an instrument is around 0.4286.

The likelihood of a student not playing an instrument, provided they play a sport, is:
[tex]Probability=\dfrac{Number\ of\ students\ who\ play\ a\ sport\ but\ do\ not\ play\ an\ instrument​}{Number of \students\ who\ play\ a\ sport}[/tex]

It is known that 14 students participate in a sport, while 8 students do not engage in either a musical instrument or a sport. Thus, the number of students who play a sport but do not play an instrument is:

Number of students who play a sport but do not play an instrument = 14- 6
                                                                                                                 = 6
Now, let's calculate the probability:

In the question ,

it is given that ,

the explicit formula is u(n) = 4n - 1 .

and u(n) = 1 ,

we need to find the recursive formula ,

We substitute n + 1 in place of n , in the equation u(n) = 4n - 1

after substitution , we get

u(n+1) = 4(n + 1) - 1

u(n+1) = 4n + 4 - 1

u(n+1) = 4n + 3

Subtracting u(n) = 4n - 1 from u(n+1) = 4n + 3  ,

we get

u(n+1) - u(n) = 4n + 3 - (4n - 1)

u(n+1) - u(n) = 4n + 3 - 4n + 1

u(n+1) - u(n) = 3 + 1

u(n+1) - u(n) = 4

u(n+1) = u(n) + 4

The amount owed at the end of the 6 years duration is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

The total student increases by 10.85% from last year.

A relative value indicating hundredth parts of any quantity is called percentage.

Given that, last there were 125 boys and 50 girls, and it increased by 12% and 8% next year,

Total students last year = 125+50 = 175

Boys increased = 125x112/100 = 140

Girls increased = 50x108/100 = 54

Total students current year = 140+54 = 194

Percentage increase = (194-175)/175x100 = 10.85%

The probability that the sample mean falls between 4800 psi and 5200 psi is 0. 0.9973.

Probability refers to the numerical descriptions of how likely an event is to occur. For the given information, the mean µ = 5000 psi and standard deviation σ = 400 psi.

For a random sample, n = 36, in order to determine the probability that the sample mean falls between 4800 psi and 5200 psi, the z test statistics for the range must be calculated.

z = (x - µ)/ (σ/√n) = (4800 - 5000)/ (400/√36) = -3

z = (x - µ)/ (σ/√n) = (5200 - 5000)/ (400/√36) = 3

Hence, the probability that the sample mean falls between 4800 psi and 5200 psi would be p ( -3< z < 3).
