What is the equation of the circle if the radius is 9 and the center is (2,7)
The equation of a circle that has a radius of 9 and a center at (-2, 7) is the option;
(x + 2)² + (y - 7)² = 81What is the definition of a circle?A circle is a set that comprises all points that are equidistant from a point on a plane
The general form of the equation of a circle is; x² + y² + 2•g•x + 2•f•y + c = 0
The equation of a circle can also be presented in standard form as follows;
(x - h)² + (y - k)² = r²Where;
(h, k) = The coordinates of the center of the circle
r = The measure of the length of the radius of the circle
The given parameters are;
The radius of the circle, r = 9
Taking the coordinates of the center of the circle, (h, k) = (-2, 7)
The equation of the circle in standard form is therefore obtained by plugging in the values of h, k, and r as follows;
(x - h)² + (y - k)² = r²
Which gives;
(x - (-2))² + (y - 7)² = 9²
Which gives;
(x + 2)² + (y - 7)² = 9² = 81
The equation of the circle is therefore the option;
(x + 2)² + (y - 7)² = 9² = 81Learn more about the equation of a circle given the center and radius here:

Write a two-column proof to prove that vertical angles are congruent.
The manipulatives and paragraph forms are the two-column proof to prove that vertical angles are congruent.
Using manipulatives: Draw the same two intersecting lines on the paper. Then, fold the paper along the line via the joint. The fold bisects the other two borders, but only the lines of the folded border which are on top of each other are required. The edges check and lie straight on top of each separately. This folding procedure can be utilized with two vertical corners. As a result, the vertical angles are the same.
Paragraph Form: When ∠1 and ∠3 are connected to ∠2, they form a linear pair. This indicates that whether added dimension ∠2 to dimension ∠1 or dimension ∠2 to dimension ∠3, the total is 180°. That is, the measures of 1 and 3 are equal to the sum left before adding ∠2. As a result, the angles are the same. This argument applies to all pairs of vertical angles.

Given ^PRS = ^CFH, find the values of x, y, and z.
Answer:
x = 23, y = 7, z = 11
Step-by-step explanation:
Since triangle PRS is congruent to triangle CFH,
PS = CH = 39
2x - 7 = 39
2x = 46
x = 23
Angle PRS = Angle CFH = 90°
13y - 1 = 90
13y = 91
y = 7
Sum of angles in a triangle add up to 180°.
Angle CHF = 180 - 90 - 28 = 62°
6z - 4 = 62
6z = 66
z = 11

Dan created a map of the state of ohio using a scale factor of 2 centimeters 25 miles The actual distance from cleveland to Columbus is 142 miles. About how far apart are Cleveland and Columbus on Dan's map
On Dan's map the distance between Cleveland and Columbus is 11.36 centimeters .
In the question ,
it is given that ,
the scale factor of Dan's map is 25 miles = 2 cm
So , 1 mile = 2/25 cm
= 0.08 cm
So , on Dan's map 1 mile is represented by 0.08 cm
Given that the actual distance between Cleveland and Columbus is 142 miles .
So , on Dan's map
142 miles = 0.08*142 cm
= 11.36 cm
we get , 142 miles = 11.36 cm

The amount that Reshma spent on comic books is Rs. 165.
The amount that is left with her is Rs. 495.
How much did she spend on comic books?A fraction is a quantity that is not a whole number. A fraction consists of a numerator and a denominator. An example of a fraction is 1/4. 1 is the numerator and 4 is the denominator.
In order to determine the amount she spent on comics, multiply the fraction spent by the amount of her pocket money. Multiplication is the process used to determine the product of two or more numbers. The sign that represents multiplication is ×.
Money spent on comics = fraction of the money spent x pocket money
1/4 x 660 = Rs. 165
The amount left can be determined by subtracting the amount spent on comics by the value of her pocket money.
Amount left = pocket money - amount left
Rs 660 - Rs 165 = Rs 495

The differential equation of the amount of a subject memorized in time t > 0 is k. a(t) + da(t)/dt = km, where k is a constant representing the rate at which a subject is memorized.
Translate the given word problem into an algebraic expression.
Let m be the total amount of a subject to be memorized.
Let a(t) be the amount memorized in time t > 0.
Let c(t) be the amount that is left to be memorized in time t > 0.
Then,
c(t) = m - a(t)
From the problem, the rate at which a subject is memorized is assumed to be proportional to the amount that is left to be memorized. It means:
da(t)/dt = k. c(t), where k is a constant
da(t)/dt = k. (m - a(t))
k. a(t) + da(t)/dt = km

By using linear equation, When the swimsuit was twice as much as the goggles and the swim cap was half the price of the goggles. If the total cost of the items was $59.50, then the price of the swimsuit is $34
The total cost of the items = $59.50
Consider the cost of goggles = 2x
The swimsuit was twice as much as the goggles
The cost of the swimsuit = 4x
Swim cap was half the price of the goggles
The cost of the swim cap = x
Then the price of the items = The cost of goggles + The cost of the swimsuit + The cost of the swim cap
Substitute the values in the equation
2x + 4x + x = 59.50
7x = 59.50
x = $8.5
The cost of the swimsuit = 4x
= 4×8.5
= $34

How to find the angles in parallel lines?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.
The value of x that makes the line l, m and n parallel can be calculated as follows:
124 + 5x - 4 = 180 (supplementary angles)
124 - 4 + 5x = 180
120 + 5x = 180
subtract 120 from both sides of the equation
120 - 120 + 5x = 180 - 120
5x = 60
divide both sides by 5
x = 60 / 5
x = 12
