Answer:

(x-4)² + (y+3)² = 9

Step-by-step explanation:

The equation of a circle of radius r centered at (h, k) is ...

... (x-h)² + (y-k)² = r²

Subsituting your given values gives ...

... (x -4)² +(y -(-3))² = 3²

... (x -4)² +(y +3)² = 9

Answer: First option. The slope is -4 and the y-intercept is 2.

Solution:

y=-4x+2

When the equation is in the form:

y=mx+b (y isolated)

The coefficient of the variable "x" is the slope "m" of the right line. In this case the coefficient of "x" is -4, then the slope "m" is -4.

The indeoendent term is the y-intercept "b". In this case the independent term is +2, then the y-intercept "b" is 2.  

Solution:

Given equation of line [tex]y=-4x+2[/tex].

The given equation is in the form of y=mx+b, y  is isolated. So the coefficient of x is the slope of the line.

The slope of the line y=-4x+2 is -4

To find the y-intercept of the equation, substitute [tex]x=0[/tex] in the equation,

[tex]\Rightarrow y=-4(0)+2\\\Rightarrow y=2[/tex]

So,  y-intercept of the equation is [tex](0,2)[/tex].

Hence, the slope is -4 and y intercept is 2. (first option)

Graph this compound inequality 2.5 is equal to or less than x is equal to or less than 4.5

2.5 <= x < = 4.5

We graph this inequality using number line.

Here x lies between 2.5  and 4.5

While graphing, we start with closed circle at 2.5 because we have equal symbol .

Then shade till 4.5. Use closed circle at 4.5.

The graph is attached below.

Answer:

its c

Step-by-step explanation:

for the rest of the question when it asks "which scenario fits the compound inequality?"

y = - [tex]\frac{2}{5}[/tex] x - 2

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 2x + 5y = 10 into this form

subtract 2x from both sides

5y = - 2x + 10 ( divide all terms by 5 )

y = - [tex]\frac{2}{5}[/tex] x + 2 ← point- slope form with slope m = - [tex]\frac{2}{5}[/tex]

Parallel lines have equal slopes hence

y = - [tex]\frac{2}{5}[/tex] x + c is the partial equation of the parallel line

to find c, substitute ( 5, - 4 ) into the partial equation

- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2

y = - [tex]\frac{2}{5}[/tex] x - 2 ← equation of parallel line

The equation of the line that is parallel to 2x + 5y = 10 and passes through the point (5, -4) is y + 4 = (-2/5)x + 2.

To find the equation of a line that is parallel to another line, we need to use the fact that parallel lines have the same slope. First, let's write the given equation in slope-intercept form (y = mx + b), where m represents the slope:

2x + 5y = 10

5y = -2x + 10

y = (-2/5)x + 2

Since the given line has a slope of -2/5, the parallel line will also have a slope of -2/5. Now, we can use the point-slope form of a line (y - y1 = m(x - x1)) to find the equation. Plugging in the coordinates of the point (5, -4):

y - (-4) = (-2/5)(x - 5)

y + 4 = (-2/5)(x - 5)

y + 4 = (-2/5)x + 2

I'm assuming what you mean is what can you divide 3456 by to get a natural number.

First of all every number is divisible by 1.  

Every even number is divisible by 2, so since 3456 is an even number, it can be divided by 2.  That would equal 1728.

2456 can also be divided by 3, to get 1782.  

You can also divide it by 4, to get 865.

Divided by 6, it's 576.

Divided by 8, it's 432.

And lastly, 3456 divided by 9 is 384.

So, there isn't just one single-digit number you can divide 3456 by to get a natural number.  You can divide it by 1,2,3,4,6,8, and 9.

Answer:

3.8 feet

Step-by-step explanation:

Given that the person is standing in a pool.  That means he is keeping his feet at the bottom level of the pool.  His height is 6.2 ft.  

Top of the person head above the surface of water= 2.8 feet.

Hence height of the person= Top of the person head above the surface of water+depth of the pool

6.2 = 2.8+depth of pool

Depth of pool = 6.2-2.8 = 3.4 feet.

the pool is four feet deep

Answer:  The graph is attached below.

Step-by-step explanation:  Given that the co-ordinates of the vertices of ΔRST are R(6, 6), S(3, –6), and T(0, 3).

We are given to graph ΔRST and its image after a reflection over the Y-axis.

After reflection across Y-axis, the co-ordinates of the vertices of ΔRST will follow the following transformation :

(x, y)  ⇒  (-x, y), because the sign before the x-coordinates of the vertices will get reversed.

Therefore, the co-ordinates of the vertices of the image of ΔRST will be

R'(-6, 6), S'(-3, -6) and T'(0, 3).

The graphs of both the triangles, ΔRST and its image after reflection R'S'T' is drawn in the attached figure.

We see that the vertices T and T' coincide with each other.

Answer:

d. (1, 3) and (-3, -1)

Step-by-step explanation:

Equating the expressions for y, we have ...

... x² +3x -1 = y = x +2

Subtracting x+2 gives ...

... x² +2x -3 = 0

... (x +3)(x -1) = 0 . . . . . factored form

... x = -3, 1 . . . . . . . . . . .values that make the factors zero

The second equation tells us, y = x+2, so

... For x = -3, y = -3 +2 = -1. The solution is (-3, -1)

... For x = 1, y = 1 +2 = 3. The solution is (1, 3)

(- 3, - 1 ) or (1, 3 )

Since both equations express y in terms of x, equate both sides

x² + 3x - 1 = x + 2 ( subtract x + 2 from both sides )

x² + 2x - 3 = 0

(x + 3 )(x - 1 ) = 0

equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Substitute these values into either of the 2 equations for y

y = - 3 : y = - 3 + 2 = - 1 ( using y = x + 2 )

x = 1 : y = 1 + 2 = 3

solutions are (- 3, - 1 ) or (1, 3 )

diagonal = 9√2 ≈ 12.73

the diagonal splits the square into 2 right triangles with the hypotenuse being the diagonal of the square

using Pythagoras' identity

d = √(9² + 9²) = √162 = 9√2 ≈ 12.73 ( to 2 dec. places )

To find the diagonal of a square with side lengths of 9 inches, use the Pythagorean theorem, yielding a diagonal length approximately equal to 9√2 inches.

To calculate the diagonal of a square, you can use the Pythagorean theorem for a right triangle formed by two adjacent sides of the square and the diagonal. The formula for the diagonal (d) of a square with side length (s) is given by d = s√2. Therefore, the diagonal of the square is:

d = 9√2

d = 9 × 1.414 (approx)

d = 12.726 inches (approx)

Rounded to the nearest whole number or given options, the length of the diagonal is closer to 9√2 inches.

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

here the vertex = (6, - 2 ) and a = 1

y = (x - 6 )² - 2 ← in vertex form

(b)

to find the zeros let y = 0

(x - 6 )² - 2 = 0 ( add 2 to both sides )

(x - 6 )² = 2 ( take the square root of both sides )

x - 6 = ±√2 ← ( note plus or minus )

add 6 to both sides

x = 6 ±√2 ← zeros

(c)

to obtain standard form expand the vertex form of the equation

y = x² - 12x + 36 - 2

y = x² - 12x + 34 ← in standard form

Answer:

Area of the Scale drawing is [tex]72[/tex] square inches.

Step-by-step explanation:

First we need to convert feet and inches to a common unit. For that lets convert feet into inches.

1 feet = 12 inches

Therefore,

The length of the floor in inches:

[tex]36[/tex] feet = [tex]36*12[/tex] inches

                           =[tex]432[/tex] inches

The width of the floor in inches:

[tex]32[/tex] feet = [tex]32*12[/tex] inches

                           =[tex]384[/tex] inches

Now lets calculate by how many times the length has been scaled down:

432 inches of length has been reduced to 9 inches.

[tex]\frac{432}{9}=48[/tex]

So the length has been scaled down 48 times.

Now lets scale down the width 48 times:

[tex]\frac{384}{48} =8[/tex]

So the width of the Scale drawing is 8 inches.

Area of the Scale drawing = Scaled down length * Scaled down width

                                            =[tex]9*8[/tex]

                                            =[tex]72[/tex] square inches

Answer:

72 square inches.

Step-by-step explanation:

Convert feet and inches.

36 feet = 36*12  inches

                          =432 inches

Width of the floor; Converted from feet to inches:

32 feet = 32*12  inches

                          = 384 inches

Calculate how many times the length (l) has been scaled down.

432 inches of length has been reduced to 9 inches.

[tex]\frac{432}{9}=48[/tex]

Now the length has been scaled down 48 times.

Scale down the width (w) 48 times.

[tex]\frac{384}{48} =8[/tex]

The width of the scale drawing = 8 in

Area of the Scale drawing = Scaled down length * Scaled down width

                                        [tex]=9*8 =72in^{2}[/tex]

First, I should point out that g(x) should be written as g(x)=(x+2)/3, otherwise the problem is confusing.

(A) [tex]f(g(x))=3(\frac{x+2}{3})-2=x\\g(f(x))=\frac{3x-2+2}{3}=x[/tex]

(B) Since [tex]f(g(x))=x[/tex] and [tex]g(f(x))=x[/tex], it holds that

[tex]f(g(x))=g(f(x))[/tex] for all x. This means the composed functions are *identical*

A

f(g(x)) = f([tex]\frac{x+2}{3}[/tex]) = 3([tex]\frac{x+2}{3}[/tex]) - 2 = x + 2 - 2 = x

g(f(x)) = g(3x - 2) = [tex]\frac{3x-2+2}{3}[/tex] = [tex]\frac{3x}{3}[/tex] = x

B

Since both composite functions f(g(x)) and g(f(x)) equal x

This indicates that the functions f(x) and g(x) are inverse functions

When you want a parallel line through a given point (h, k), you can start with the equation you have and do the following:

Here, that looks like

... y = -2x -200 -100 . . . . . eliminate parentheses, add -100

... y = -2x -300 . . . . the equation you want.

Answer:

y = - 2x - 100

Step-by-step explanation:

Remark

The line we want is a line parallel to y = - 2x + 3

That means it has the same slope as the given line.  The given line has a slope of  -2

y = -2x + b is what you have so far. Now you have to use the point to get b

y = - 100

x = - 100

Solve for b

-100 = -2(-100) + b

-100 = 200 + b       Notice the sign change. Two minus's make a plus. Subtract 200 from both sides.

- 100 - 200 = b

- 300 = b

Answer

y = - 2x - 100
