Answer: (x -4)^2 +(y -7)^2 = 36

Step-by-step explanation: The equation of a circle with radius r and center at (h, k) is ...

 (x -h)^2 +(y -k)^2 = r^2

When the diameter is 12, the radius is 6 (half the diameter). Then for your center point, the equation is ...

 (x -4)^2 +(y -7)^2 = 36

Answer:

No

Step-by-step explanation:

The tangent line must form a right angle with the radius

No, 4 5 6 isn't a right triangle

Answer:

Line m is not a tangent line to circle B.

Step-by-step explanation:

The tangent line to a circle is always perpendicular to the radius.

The line segment measuring 4 units is the radius of Circle B, therefore if line m is a tangent line to the circle, the angle between this segment and the segment measuring 5 units will be a right angle (90°).

We can use Pythagoras' Theorem to check if the triangle is a right triangle.

Pythagoras’ Theorem:  [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

Therefore, the legs are the line segments measuring 4 and 5, and the hypotenuse is the line segment measuring 6 units.

Substituting the values for the legs into the formula:

[tex]\implies 4^2+5^2=c^2[/tex]

[tex]\implies 16+25=c^2[/tex]

[tex]\implies 41=c^2[/tex]

[tex]\implies c=\sqrt{41}[/tex]

Therefore, as the hypotenuse of the triangle is not √41, the triangle is not a right triangle, and therefore line m is not a tangent line to circle B.

Check the picture below.

so the prism is a "right square" prism, namely it has only right-angles and two of its faces are a square, namely the front and back.  We know it has a surface are of 220 cm², so let's check what the width "w" is first.

[tex]\stackrel{\textit{\huge surface area}}{\stackrel{\textit{front and back}}{2(5)(5)}~~ + ~~\stackrel{\textit{left and right}}{2(5)(w)}~~ + ~~\stackrel{\textit{top and bottom}}{2(5)(w)}}~~ = ~~\stackrel{cm^2}{\textit{\Large 220}} \\\\\\ 50~~ + ~~10w~~ + ~~10w~~ = ~~220\implies 50+20w=220\implies 20w=170 \\\\\\ w=\cfrac{170}{20}\implies w=\cfrac{17}{2} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\stackrel{\textit{\huge volume}}{\stackrel{length}{(5)}~~\stackrel{height}{(5)}~~\stackrel{width}{\left( \cfrac{17}{2}\right)}}\implies \cfrac{425}{2}\implies 212.5[/tex]

Answer:

Mean: 3 Mad: 1/3

Step-by-step explanation:

First we need to find out the numbers, so to get a mean of 3 we have to get to 9 ebcause there are 3 arrows.

2nd: Once you find the numbers which are 2.5, 3, and 3.5 you add them together and divide it by 3 to get 3 the mean

3rd: Find the MAD but adding .5 and .5 to get 1 then divide it by 3 and you get 1/3 as the MAD.

The archer's mean distance in the second round is 1.6 inches and the MAD is 0.83 inches.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

Let's first recall that MAD stands for Mean Absolute Deviation, which is a measure of the variability of a set of data.

The MAD is calculated by taking the absolute value of the difference between each data point and the mean, and then finding the average of those absolute values.

Let the mean distance of the archer's arrows in the second round be m, and let the MAD be d.

In the first round, the archer's mean distance was 1.6 inches and the MAD was 1.3 inches.

This means that the absolute difference between each arrow's distance from the mean was, on average, 1.3 inches.

In the second round, the archer's arrows were farther from the center, so we expect the mean distance to be larger than 1.6 inches.

However, the arrows were more consistent, so we expect the MAD to be smaller than 1.3 inches.

To find the new value for the mean distance, we can use the fact that the sum of the distances from the mean is equal to zero. This means that:

3(m - mean) = 0

Solving for m, we get:

m = mean

Therefore, the mean distance in the second round is equal to the mean distance in the first round, which is 1.6 inches.

To find the new value for the MAD, we can use the fact that the variance (the square of the standard deviation) is equal to the average of the squared differences between each data point and the mean.

This means that:

Var = (1/3)(d²)

Since the arrows in the second round are more consistent, we expect the variance to be smaller than in the first round.

Therefore, we can set the new variance to be some fraction f of the old variance, and solve for the new value of d:

f(Var) = (1/3)(d²)

d² = 3f(Var)

d = √(3f(Var))

We don't know the exact value of f, but we do know that it is less than 1 since the variance is decreasing.

Let's assume that f = 0.5 for simplicity.

Using this value of f and the given values for the mean and MAD in the first round, we get:

Var = (1/3)(1.3³) = 0.56

d = sqrt(30.50.56) = 0.83

Therefore,

The archer's mean distance in the second round is 1.6 inches and the MAD is 0.83 inches.

Well, you need to know the aton mic weight of Platinum (Pt) and the number of atoms per mole. The answer to the former is 195.084 g/mole and the latter is 6.023 * 10^23 atoms/mole. Then, multiply everything as shown below:

Number of atoms = (1 g) * (1/195.084 g/mole) * 6.023 * 10^23 atoms/mole

Number of atoms = 3.087 * 10^21 atoms

Note, I’ve included units on everything and you can see that they all cancel except for atoms. Dragging the units along can be a pain but it is a great way to check that they way the numbers are being combined is

Inequalities help us to compare two unequal expressions. The number of seats in each row on the floor must be less than 18.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

Given the balcony has 400 seats, and the floor has 50 rows with each row having x number of seats. Therefore, the number of seats on the floor will be,

Number of seats on floor = 50 × x = 50x

Since the total number of seats in the auditorium should be less than 1300, therefore, the inequality can be written as,

Number of seats in balcony + Number of seats on floor < 1300

400 + 50x < 1300

50x < 1300-400

50x < 900

x < 18

Hence, the number of seats in each row on the floor must be less than 18.

The first equation will be x²-12x+27=(x-9)(x-3). The second equation will be x²-9x+20=(x-5)(x-4).

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

1. For the first equation to be complete, we need to expand the factors, therefore, we can write,

(x-9)(x-3)

= x² - 9x - 3x + 27

=x²-12x+27

Hence, the first equation will be x²-12x+27=(x-9)(x-3).

2. For the second equation to be complete, we need to factorise the left side of the equation, therefore, we can write,

x²-9x+2

= x²-5x-4x+20

= x(x-5)-4(x-5)

=(x-5)(x-4)

Hence, the second equation will be x²-9x+20=(x-5)(x-4).

the equation of a quadratic in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (1, - 4 ) , then

y = a(x - 1)² - 4

to find a substitute the coordinates of any other point on the graph into the equation.

using (0, - 3 )

- 3 = a(0 - 1)² - 4 ( add 4 to both sides )

1 = a(- 1)² = a ⇒ a = 1

y = (x - 1)² - 4 ← in vertex form

B

the equation of a quadratic in standard form is

y = ax² + bx + c ( a ≠ 0 )

using the result from A

y = (x - 1)² - 4 ← expand the factor using FOIL

  = x² - 2x + 1 - 4

y = x² - 2x - 3 ← in standard form

So as we know, 30/x = 100/80

100/80 = 1.25

Now we have 30/x = 1.25

Multiply both sides of the equation by x - (30/x)x = (1.25)x

Now we have 30 = 1.25x

Divide both sides by 1.25 - 30/1.25 = 1.25x/1.25
