3. [tex](x+3)^2+(y+11)^2=\sqrt{51}[/tex]
4. [tex](x+3)^2+(y-0)^2=25[/tex]
For Questions 1-2:Step 1: Formula
The standard form of a circle is [tex](x-h)^2+(y-k)^2=r^2[/tex].
The h represents the x value of the coordinates of the circle's center and the k is the y value of the coordinates. The r is the radius.
So in the first problem h is going to be 3 and k is going to be -15. (In this problem the signs are flipped, so if you have a positive number it will be negative in the formula)
After inserting the values in the formula you have your answer of [tex](x-3)^2+(y+15)^2=r^2[/tex]. Now let us find the radius
Step 2: Find the radius
To find the radius of the first two problems what you can do is you can use the distance formula.
To use the distance formula you find have to identify the (x1, y1) and the (x2, y2)
In the first problem, the (x1, y1) would be the center of the circle. The reason for this is that on a graph you have to read it left to right (kinda like English) so to find the values you have to imagine what values would come first, in this case, the center point would come first.
So let us input the values in the formula. The formula is [tex]d = \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }[/tex]. This is the distance formula, this formula will be used in this problem.
Okay so the x1 is 3 and the y1 is -15. The x2 is 0 and the y2 is -13. So lets us input these values.
[tex]d = \sqrt{(0-3)^{2}+(-13--15)^2 } \\\\ = \sqrt{(-3)^{2}+(2)^2} \\\\=\sqrt{9+4}\\\\=\sqrt{13}\\\\= 3.605[/tex]
3.605 is our radius.
Now let us write our finished equation.
[tex](x-3)^2+(y+15)^2=\sqrt{13} ^2[/tex] or [tex](x-3)^2+(y+15)^2=13[/tex].
Doing these steps for the next problem gives us our second answer of [tex](x+9)^2+(y+14)^2=5[/tex]
For Questions 3-4:Step 1: Midpoint Formula
To solve this problem you need to use the midpoint formula. The midpoint formula is [tex]\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2}[/tex]. In the first problem, the x1 would be -10, the y1 would be -13. The x2, on the other hand, is 4 and the y2 is -9. Now find the center of the circle.
Step 2: Find the center
To find the center of the circle we need to insert the values of x and the values of y into the midpoint formula. We can do this because they gave us the diameter and the diameter goes through the middle of the circle. So we can do this.
[tex]\frac{-10 + 4}{2} ,\frac{-13+-9}{2}\\\\\frac{-6}{2} ,\frac{-22}{2}\\\\(-3,-11)[/tex]
So (-3, -11) is the center of the circle.
Step 3: Find the radius
Now that we have the center of the circle we can use the distance formula to find the radius. We already have two of the ends of the radius so we can simply use the distance formula with the center and the ends.
[tex]d = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }\\\\=\sqrt{(4--3)^2+(-9--11)^2 }\\\\= \sqrt{(7)^2+(2)^2 }\\\\=\sqrt{49+4 }\\\\=\sqrt{51}[/tex]
Step 4: Write your final equation
Know we can insert all the values we have into the standard form of a circle equation.
[tex](x-h)^2+(y-k)^2=r^2\\\\(x+3)^2+(y+11)^2=\sqrt{51} ^2[/tex] or [tex](x+3)^2+(y+11)^2=\sqrt{51}[/tex]. This is our answer.
Doing these steps for the next problem gives us our answer of [tex](x+3)^2+(y-0)^2=25[/tex]

Based on the information about the angles, the value of x is 10.
How to calculate the value of xFrom the information, n - 2 = 43
Solving for n, we get:
n = 45
The polygon has 45 sides.
sum of interior angles = (n - 2) * 180 degrees
sum of interior angles = (45 - 2) * 180 degrees
sum of interior angles = 7560 degrees
Since the polygon is regular, all of its angles have the same measure, which we are told is (17x+2)°. Let's use this to find x:
sum of interior angles = number of angles * measure of one angle
7560 = 45 * (17x+2)
7560 = 765x + 90

Reflection across y-axis: (-x, y)
Reflection across x-axis: (x, -y)
7 - Correct
8 - Correct
9 - Correct
10 - This is correct, but your work is incorrect. The formula for reflection across the y-axis is (-x, y). So, you have to take all the points and make their x-values negative. A is located at (-2, -5). -2 = x, so -(-2) = 2 because negative x negative = positive. A' is located at (2, -5), D' is not. C' = (2, 0) is correct, because C is located at (-2, 0). B' = (3, 0) is correct because B was originally at (-3, 0). D' is located at (-2, -2) because D was originally located at (2, -2). So, all you have to do is swap what you wrote for A and D next to the graph, but the graph is completely correct.
11 - Correct
12 - Your answer for 12 isn't visible. I can see you said that P is located at (3, -2) and that P' is located at (-4, -1) which is correct. This means that (x - 7, y + 1) is the correct rule for this question because 3 - 7 = -4 and -2 + 1 = -1.
13. Your answer for 13 is incorrect. This is a reflection across the x-axis, not a translation. So there should be no adding/subtracting in the rule. The formula for reflection across the x-axis is (x, -y). We can find if this graph is a reflection across the x-axis by seeing if each of the prime versions of the original coordinates are a negative y version of the original coordinates.
U is located at (-4, 4), V is located at (-2, 4), and T is located at (-5, 2).
U' is located at (-4, -4), V is located at (-2, -4), and T is located at (-5, -2).
Since U' is located at (-4, -4) and U is located at (-4, 4), the y value turned negative, meaning that U' was a reflection across the x-axis because of (x, -y). Since V' and T' have negative y values of their corresponding original coordinates, Triangle U'V'T' is a reflection over the x-axis.
So, the correct rule you should put for question 13 is (x, -y).
14 - Correct
15 - Incorrect. All y-values turned negative, meaning this is another case of reflection over the x-axis. The correct rule is (x, -y).
16 - Correct
17 - Correct
18 - Correct
19 - Correct
20 - Incorrect. This was a translation over the x-axis, because all y-values turned negative. The correct rule is (x, -y).
For example, J is located at (-1, -1). J' is located at (-1, 1). The y-value turned negative because -(-1) = 1.
--Suggestion: Keep the formulas for the reflection across the x-axis and y-axis by you while doing homework like this.
Reflection across the x-axis formula: (x, -y).
Reflection across the y-axis formula (-x, y).
Translation up/down: (x, y +/- __)
Translation right/left: (x +/-, y)
Apply these formulas to each coordinate, not just one, to see if they all match up.

How to Determine the Series of Transformation?If two shapes are congruent to each other, it means they have the same shape and size. The only series of transformation that can be used to produce an image that is congruent to a preimage of a shape is either a translation, rotation, or a reflection. This therefore implies that any transformation that involves a dilation will not produce congruent images of a shape but would rather produce similar images.
Therefore, option A, B, and C, which involves dilation cannot produce quadrilateral H' that is congruent to quadrilateral H.
The series of transformation that can produce that is: D. a translation of 6 units down, a rotation, and then a reflection.

Priya hiked 1 2/3 miles. Diego hiked 1/2 mile. How much farther did Priya hike than Diego?
Answers
By taking the difference between the distances, we see that Priya hiked (1 + 1/6) miles more than Diego.
How much farther did Priya hike than Diego?To find this, we just need to take the difference betwee the two distances given.
We know that Priya hiked 1 2/3 miles and Diego hiked 1/2 mile, then the difference is:
D = (1 + 2/3) mi - (1/2) mi
D = (1 + 2/3 - 1/2) mi
D = (1 + 4/6 - 3/6) mi
D = (1 + 1/6) mi
We can see that Priya hiked (1 + 1/6) miles more than Diego.

The distance farther Priya hike than Diego is 1 1 / 6 miles.
How to find distance travelled?Priya hiked 1 2/3 miles. Diego hiked 1/2 mile. Therefore, let's find how much farther Priya hiked than Diego.
Hence,
Distance hiked by Priya = 1 2 / 3 = 5 / 3 miles
Distance hiked by Diego = 1 / 2 miles
Therefore,
Amount of distance farther Priya hiked than Diego = 5 / 3 - 1 / 2
Amount of distance farther Priya hiked than Diego = 10 - 3 / 6
Amount of distance farther Priya hiked than Diego= 7 / 6 miles
Amount of distance farther Priya hiked than Diego = 1 1 / 6 miles

Mason would receive $10,000 every year for five years. The rate of interest is 10%. What would be the present value of the amount that would be received by Mason at the end of five years?
Answers
The present value of the payments that Mason would receive over five years is $37,901.
How to Calculate the Present Value of Amount?To find the present value of the payments that Mason would receive over five years, we can use the present value formula for an annuity:
PV = PMT x [1 - (1 + r)^(-n)] / r
Where we have:
PV = present value of the payments
PMT = amount of each payment ($10,000 in this case)
r = interest rate per period (10% or 0.10 in this case)
n = total number of periods (5 in this case)
Plug in the values:
PV = $10,000 x [1 - (1 + 0.10)^(-5)] / 0.10
PV = $10,000 x [1 - 0.6209] / 0.10
PV = $10,000 x 3.7901
PV = $37,901
