Answer:
(x -h)² +(y -k)² = r²r(h, k)Step-by-step explanation:
You are being asked for the equation of a circle, and a description of what it is.
Points equidistantThe distance equation tells you that the distance of (x, y) from (h, k) is ...
d = √((x -h)² +(y -k)²)
If this distance is r, the radical can be removed, and we can write the equation as ...
(x -h)² +(y -k)² = r² . . . . formula for P(x, y)
DescriptionThis is a circle of radius r, with a center at (x, y) = (h, k).
The equation of a circle of radius r with center at (x, y) = (x -h)² +(y -k)² = r².
Given that, P(x, y) is a distance r>0 from a fixed point C(h, k).
What is a circle equation?The equation of circle provides an algebraic way to describe a circle, given the center and the length of the radius of a circle. The equation of a circle is different from the formulas that are used to calculate the area or the circumference of a circle.
The standard equation of a circle with center at (x1,y1) and radius r is (x-x1)²+(y-y1)²=r²
Using distance formula,
The distance between (x, y) from (h, k) is
d = √((x -h)² +(y -k)²)
If this distance is r, then we get
(x -h)² +(y -k)² = r²
Hence, the equation of a circle of radius r with center at (x, y) = (x -h)² +(y -k)² = r².

in a table that shows no exact solutions, how do you know if there are any solutions? How can you find an approximate solution?
If we have a quadratic equation described in a table and it does not show the exact solution (roots) of the equation, we can look if, with the values of x or the independent variable sorted, we have a change of sign.
This indicates that there is a root between those two values of x.
For example:
x = 2 --> f(x) = -3
x = 3 --> f(x) = 4
We can see that from x=2 to x=3, we have a sign change. Then we know that, because of the continuity of the quadratic function, we must have a value between x=2 and x=3 for which f(x)=0. This is an application of the Intermediate Value Theorem.
We can then approximate the value of the root x=r as the average between x=2 and x=3. This is the bisection method to find roots of functions. In this case, it would give a result r=2.5.
There are other methods (Newton-Raphson or False position, for example), but this bisection method is the simplest approximation.
If Rolle's Theorem can be applied, find all values of c in the open interval (a, b) such that f '(c) = 0. (Enter your answers as a comma-separated list. If Rolle's Theorem cannot be applied, enter NA.)
Since we can apply Rolle's Theorem:
[tex]\begin{gathered} f^{\prime}(x)=-\sin (x) \\ so\colon \\ f^{\prime}(x)=0 \\ -\sin (x)=0 \end{gathered}[/tex]Take the inverse sine of both sides:

Given Point A, what is the coordinate for A' after the following transformation has occurred?(x, y) + (x – 5, -y + 2)A (5, 7)
So we have the point A=(5,7) and the following transformation:
[tex](x,y)\rightarrow(x-5,-y+2)[/tex]Transformations take a point as input and return another point that usually is different than the one used as input. Since our input is (5,7) then we just need to replace 5 and 7 in place of x and y on the transformation:
[tex]\begin{gathered} A^{\prime}=(x-5,-y+2)=(5-5,-7+2)=(0,-5) \\ A^{\prime}=(0,-5) \end{gathered}[/tex]Then, the point we are looking for is A'=(0,-5).
What is the slope-intercept form of a line? What two specific pieces of information do you need to write an equation of a line in slope-intercept form? Explain/discuss how you would find those two pieces of information if you were only given two points on the line. Use the points (-3,1) and (3,-5) to illustrate this process.
The slope-intercept form of a line is:
y = ax + b
In which a is the slope and b is the y-intercept, which is the value of y when x = 0.
To write an equation in this form, we need the slope and the y-intercept.
Using two points, we find the slope a dividing the change in y by the change in x. Then, having a, we can replace one of these points into the equation, to find the intercept b.
In this question:
We have points (-3,1) and (3,-5)
Finding the slope:
Change in y: -5 - 1 = -6
Change in x: 3 - (-3) = 3 + 3 = 6
Slope: a = -6/6 = -1
So
y = -x + b
Using the point (-3,1), we have that when x = -3, y = 1. So
1 = -(-3) + b
1 = 3 + b
3 + b = 1
b = 1 - 3
b = -2
The equation is:
y = -x - 2

1. Find the domain and range of f(x) = sqrt(x)2. Find the domain and range of f(x) = 3x + 2
We have the function:
[tex]f(x)=\sqrt[]{x}[/tex]The domain is the set of values of x for which f(x) is defined. In this case, f(x) is defined only for non-negative values of x, so the domain is D:{x≥0}.
The range is the set of values that f(x) can take for the domain in which it is defined. In this case, f(x) will only take non-negative values, so the range can be defined as R: {y≥0}.
For the linear function f(x) = 3x+2, we don't have restrictions for the domain and the the range: both x and y can take any real value, so the domain and range are D: {x: all real numbers} and R: {y: all real numbers}.
Answer:
For the function f(x) = √x, the domain is D:{x≥0} and the range is R: {y≥0}.
For the function f(x) 3x+2, the domain is D: {x: all real numbers} and the range is R: {y: all real numbers}.

He wants to reduce the width by 6 feet and increase the length by 6 feet.Let xrepresent the length of one side of the square patio Write expressions for the length and width of the new patio. Then find the area of the new patio if the original patio measures 13 feet by 13 feet.
Explanation:
Ezra has a square brick patio where x represents the length of one side of this square patio:
And hee wants to reduce the width by 6 feet, and increase the length by 6 feet.
The new width is x-6,
The new length is x+6.
[tex]\begin{gathered} Expressions\text{ for the length and the width of the new patio:} \\ l=x+6 \\ w=x-6 \end{gathered}[/tex]Then, we need to find the area of the new patio:
[tex]A=lw[/tex]We multiply the length by the width. The area is:
[tex]lw=(x+6)(x-6)[/tex]And finally, if the original measure of the sides is x=13 ft, the area of the new patio is:
[tex]\begin{gathered} (x+6)(x-6) \\ \downarrow \\ (13+6)(13-6) \\ \downarrow \\ (19)(7) \\ \downarrow \\ 133 \end{gathered}[/tex]Since it represents the area the units are square feet:
133 square feet.
These results are shown in option B.
Answer:
[tex]lw=(x+6)(x-6);133\text{ square feet}[/tex]Circle B is a transformation of Circle A. Describe the transformations that show why Circle A is similar to Circle B. YA 12 Circle B is the result of dilating Circle A with A as the center of dilation and using a scale factor of . then translating the image 12 units down. 10 8 6 A А Circle B is the result of dilating Circle A with A as the center of dilation and using a scale factor of then reflecting the image in the y-axis. 4 N -2 0 -2 2 4 6 8 10 12 x -4 Circle B is the result of dilating Circle A with A as the center of dilation and using a scale factor of, then translating the image 12 units down. -6 B -8 -10 -12 Circle B is the result of dilating Circle A with A as the center of dilation and using a scale factor of then rotating the image 180°.
The two circles, A and B have different diameters. The diiameter of circle A is 5 units while the diameter of circle B is 4 units. This means that circle B is smaller than circle A. This means that there is a dilation and it is a reduction. Thus, we can say that B is 4/5 * A
4/5 * 5 = 4
The image was then translated 12 units down. The correct option is the third one

An open topped box can be created by cutting congruent squares from each of the four corners of a piece of cardboard that has dimensions of 30 cm by 40 cm and folding up the sides. Determine the dimensions of the squares that must be cut to create a box with volume of 2448cm^3.
Let's start by drawing the situation:
According to this, one of the dimensions of the box is 40-2x. The other one is 30-2x and the last one, that we could say it's the height, is x.
The volume of a box is given by the product of the three dimensions:
[tex]\begin{gathered} V=(40-2x)\cdot(30-2x)\cdot x \\ V=(1200-80x-60x+4x^2)\cdot x \\ V=1200x-140x^2+4x^3 \end{gathered}[/tex]Use the given value of the volume to find x:
[tex]\begin{gathered} 2448=1200x-140x^2+4x^3 \\ 4x^3-140x^2+1200x-2448=0 \end{gathered}[/tex]Factoring this expression we have that:
[tex]\begin{gathered} 4(x-3)(x^2-32x+204)=0 \\ x-3=0 \\ x=3 \end{gathered}[/tex]One of the possible dimensions of the square is 3. Now, solve the quadratic expression (third factor) to find the other 2 options:
[tex]\begin{gathered} x^2-32x+204=0 \\ x=\frac{-(-32)\pm\sqrt[]{(-32)^2-4(1\cdot204)}}{2\cdot1} \\ x=\frac{32\pm\sqrt[]{1024-816}}{2} \\ x=\frac{32\pm\sqrt[]{208}}{2} \\ x1=\frac{32+\sqrt[]{208}}{2} \\ x2=\frac{32-\sqrt[]{208}}{2} \end{gathered}[/tex]It means that the squares can have 3 different dimensions, which are:
[tex]3,\frac{32+\sqrt[]{208}}{2},\frac{32-\sqrt[]{208}}{2}[/tex]Nevertheless, the second possible option is not coherent since it's value is close to 23 and the dimensions of the cardboard are 30 and 40. It means that the possible dimensions are 3 and (32-sqrt(208))/2.
