Answer: To find the equation of the circle, it is not necessary to find the legs of the triangle first.
The length of the legs (equal) is 3√2 or 4.243
Step-by-step explanation:
The equation for a circle is similar to the Pythagorean Theorem
a² + b² = c²
( x - h )² + ( y - k )² = r², where ( h, k ) is the center and r is the radius.
The a and b terms are changed to allow insertion of h and k to locate the center of the circle on a Cartesian plane.
You can get the information needed from
Given: radius =6 and "a center at the point (3,2)"
Substitute 3 for h and 2 for k and 6 for r
( x - 3 )² + ( y - 2 )² = 6² This is the equation of the circle .
From the diagram, it appears that x-3 = y-2
So, in the equation, we can substitute 2(x²) = 36
x² = 36/2 . x² = 18
√x² = √18 = √9(2)
x = 3√2 =4.2426
the length of the horizontal leg is 4.243
Substitute for x in to find x+3 the coordinate (x,2)
the coordinate x, 2 is (7.24, 2)
Substitute for y in to find y+2, the length of the vertical leg is 4.243.
y + 2 = 6.243
So the coordinate (x,y) on the circle is (7.24, 6.24)
This does not account for Step 1 and Step 2 in the question, matching expressions or equations to the steps. I hope you will be able to sort that our with the information here.

Answer:
y=-2/5x-6
Step-by-step explanation:
The line crosses the y axis at -6 so the y intercept is -6. The line of the graph goes down 4 and right 10 so the slope is -4/10 which is equal to -2/5 when simplified.
Answer:
y= -2/5x -6
Step-by-step explanation:
The slope is 2/5, because slope is rise over run, and the two points rise 2, and run 5. The y intercept is -6, because the line crosses the y axis at -6. Slope intercept form is y= mx+b, where x and y are the points, and slope is m, and b is y intercept. So the equation is y= 2/5x -6. HOPE THIS HELPS!! :D This is a negative slope too, so the slope is negative.
Which equation has the steepest graph?
A. y = 10x-5
B. y=3/4x-9
c. y = -14x+1
D. y = 2x + 8
The equation that has the steepest slope is y = -14x + 1
What is a slope?A slope is the ratio of the change in the y-coordinates to the change in the x-coordinates of a line segment.
Analysis:
A line is said to be the steepest if it has the highest absolute value of the gradient or slope.
From the equations, the coefficient of x in the equations is taken as the slope. y = -14x+ 1 is the equation with the highest absolute value 14. The absolute value means ignoring the minus sign, since it indicates a negative slope.

Instructions: Find the equation of the line through point (5, 1) and
perpendicular to 5x - y = -3. Use a forward slash (i.e. "/") for fractions
(e.g. 1/2 for).
make y the subject
y= 5x + 3
perpendicular line needs the reciprocal of the gradient
y = 1/5x + c
substitute in the point
1 = 1/5(5) + c
5/5 = 1 so the answer is y = 1/5x

What is the slope-point form of equation of the line?"The equation of the line having slope m and passing through points (p, q) is (y - q) = m(x - p)"
What is the slope-intercept form of the line?"y = mx + c, where m is the slope and c is the Y-intercept of the line."
For given question,
We have been given a point (5, 1)
The required line is perpendicular to the line 5x - y = -3
⇒ 5x - y = -3
⇒ - y = -5x - 3
⇒ y = 5x + 3
Comparing above equation with slop-intercept form of the line.
m = 5
Let m1 be the slope of the required line.
We know that the product of the slopes of perpendicular lines is -1.
⇒ m1 × m = -1
⇒ m1 = [tex]\frac{-1}{5}[/tex]
Now we find the equation of the required line by using slope-point form.
Let (p, q) = (5, 1)
By using slope-point form,
⇒ (y - q) = m1(x - p)
⇒ (y - 1) = [tex]-\frac{1}{5}[/tex] (x - 5)
⇒ y - 1 = [tex]-\frac{1}{5}x[/tex] + 1
⇒ y = [tex]-\frac{1}{5}x[/tex] + 2
Therefore, the required equation of the line is [tex]\bold{y=-\frac{1}{5}x+2}[/tex]

Lucio quiere repartir su colección de estampillas entre la mayor cantidad de amigos pero de manera que todos reciban la misma cantidad tiene parar repartir 30 estampillas de animales 75 estampillas de flores y 160 de ciudades del mundo cuantos grupos iguales puede armar
Answer:
Lucio podrá armar 5 grupos iguales de estampillas.
Step-by-step explanation:
El problema plantea un caso de distribución mediante la aplicación del divisor común mayor a todos los números involucrados. Para ello, primero debemos analizar los divisores de cada uno de estos números:
-30: divisible por 2, 3, 5, 6, 10, 15 y 30.
-75: divisible por 3, 5, 15, 25 y 75.
-160: divisible por 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 y 160.
Así, podemos ver que el divisor común mayor a los tres números es 5, ya que 30, 75 y 160 dan como resultado un número entero tras ser divididos por 5.
Entonces, para poder repartir equitativamente sus estampillas entre la mayor cantidad de amigos posibles, deberá repartir 6 estampillas de animales, 15 estampillas de flores y 32 estampillas de ciudades a 5 amigos. De esta manera, Lucio podrá armar 5 grupos iguales de estampillas.

Which phrase represents the algebraic expression 3p+6/7p-9
Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine

Find the range of the given function y = 5x + 2, where x > -2.
Answer:
{-3, 2, 7, ...... } is the range of given function.
Step-by-step explanation:
We are given that the function is defined as:
[tex]y = 5x + 2[/tex] where [tex]x > -2[/tex].
To find:
Range of the given function = ?
Solution:
First of all, let us have a look at the definition of Domain and Range.
Domain of a function f(x) is the set of input that is valid i.e. the value of x which are valid.
For example, in the given question, x > -2 i.e. x can be any value from the set {-1, 0, 1, 2, ......} is the domain of given function.
Range of a function f(x) is the set of output that is valid according to the input given.
For the given equation, let us put the value of x one by one and try to find out the value of y.
Putting x = -1 first:
[tex]y = 5 \times -1+2\\\Rightarrow y=-3[/tex]
Putting x = 0:
[tex]y = 5 \times 0+2\\\Rightarrow y=2[/tex]
Putting x = 1:
[tex]y = 5 \times 1+2\\\Rightarrow y=7[/tex]
So, the range is : {-3, 2, 7,......}

Step-by-step explanation:
Which statements are true regarding the transformation? Check all that apply.
EF corresponds to E'F'.
FG corresponds to G'D'.
∠EDG Is-congruent-to ∠E'D'G'
∠DEF Is-congruent-to ∠D'E'F'
The transformation is not isometric.
The transformation is a rigid transformation.
Answer: Transformation is the moving of the location of a point from one place to another. If an object is transformed, all the points of the object are also transformed. There are four types of transformation: reflection, dilation, rotation and translation.
Points DEFG is mapped to D’E’F’G, The corresponding lengths and angles of the parallelogram still remains the same, Therefore the following applies:
EF corresponds to E'F'.
∠EDG Is-congruent-to ∠E'D'G'
∠DEF Is-congruent-to ∠D'E'F'
FG does not corresponds to G'D' because their lengths are not corresponding but are adjacent.
The transformation is a rigid transformation. A rigid transformation (isometric) preserves the length of the object.
Answer:
EF corresponds to E'F'
<EDG=<E'D'G'
<DEF=D'E'F'
The transition is a rigid transformation

They can leave tonight by bus, or they can save two hours by leaving tomorrow morning and using the express train which travels 20 km/h faster than the bus. If the distance between South Central High and Calgary is 800 km, determine how long it will take to travel by bus, rounded to the nearest hour.
Answer:
The bus will take 10 hours to travel from South Central High to Calgary.
Step-by-step explanation:
Let suppose that both bus and express train travels at constant speed, whose kinematic formula is now described:
[tex]v = \frac{\Delta s}{\Delta t}[/tex]
Where:
[tex]v[/tex] - Speed, measured in kilometers per hour.
[tex]\Delta s[/tex] - Travelled distance, measured in kilometers.
[tex]\Delta t[/tex] - Time, measured in hours.
The transportation time is cleared afterwards:
[tex]\Delta t = \frac{\Delta s}{v}[/tex]
The kinematic expressions for the bus and the express bus are, respectively: ([tex]\Delta s = 800\,km[/tex])
Bus
[tex]\Delta t = \frac{800\,km}{v}[/tex]
Express train
[tex]\Delta t - 2\,h = \frac{800\,km}{v + 20\,\frac{km}{h} }[/tex]
By eliminating [tex]\Delta t[/tex]:
[tex]\frac{800\,km}{v} -2\,h = \frac{800\,km}{v+20\,\frac{km}{h} }[/tex]
[tex]\frac{800\,km}{v} - \frac{800\,km}{v+20\,\frac{km}{h} } = 2\,h[/tex]
[tex]800\cdot (v+20)-800\cdot v = 2\cdot v\cdot (v+20)[/tex]
[tex]16000 = 2\cdot v^{2}+40\cdot v[/tex]
[tex]2\cdot v^{2}+40\cdot v -16000 = 0[/tex]
Which is a second-order polynomial and whose roots are:
[tex]v_{1} = 80\,\frac{km}{h}[/tex] and [tex]v_{2} = -100\,\frac{km}{h}[/tex]
Only first root is physically reasonable, as speed is a scalar, that is, a number that is represented only by magnitude. Then, the time taken by the bus to travel from Central High to Calgary is: ([tex]v = 80\,\frac{km}{h}[/tex])
[tex]\Delta t = \frac{800\,km}{80\,\frac{km}{h} }[/tex]
[tex]\Delta t = 10\,h[/tex]
The bus will take 10 hours to travel from South Central High to Calgary.

Given set: [tex]B=\{3,9,27,81\}[/tex] which is in a rooster form.
A set-builder form is a mathematical form to representing a set by stating the properties that its elements must satisfy.
In the given set each element is a multiple of 3.
[tex]3=3^1\\9=3^2\\27=3^3\\81=3^4[/tex]
So, [tex]B=\{3^1, 3^2, 3^3, 3^4\}[/tex] ,where 1,2,3,4 are natural numbers
The set-builder notation would be :
[tex]B=\{3^x:x\in N, x\leq4\}[/tex], where N is the set of natural numbers.
