The equation of the circle with radius 8 and center at (5 , -2) is (x - 5)^2 + (y + 2)^2 = 64.

The general form of the equation of  circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius 8 and center at (5 , -2), substitute these values to the general form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

where (h , k) = (5 , -2)

r = 8

(x - 5)^2 + (y - -2)^2 = 8^2

(x - 5)^2 + (y + 2)^2 = 64

Let radius of circle is r=18 units

Perimeter of full circle is given by 2πr

Thus, perimeter of three quarters circle is given by,

( ¾ × 2πr) + (2 × r)

Given equation x + 2y = 15 and 3x -15 = -6y are real numbers so the equation has a solution.

Some equations have no solutions. In these equations, there is no value for the variable that makes the equation true. You can tell that an equation has no solutions if you try to solve the equation and get a false statement.

We have been given that

x + 2y = 15 ..........(1)

3x -15 = -6y ..........(2)

Multiply equation (1) with 3.

3(2y+x)=5

6y+3x=-15

Subtract equation (1) from equation (2)

0=15

Instead of 6y+3x=-15, 3x-15=-6y becomes 6y+3x=15. So, these 2 equations are saying the same thing (this is the first equation times 3), and therefore the solution is all real numbers.

Hence, The equation has a solution since the given values of x + 2y = 15 and 3x -15 = -6y are real numbers.

The required answers are-

Part a: The equation that represents the total cost C is C = 250 + 7x.

Part b: The equation that represents the average cost A per person is A = 250 + 7 = 257.

Part c: The estimate number of people who must attend before the average cost drops to $15 per meal is 25.

Part d: The average cost keeps on decreasing exponentially and then becomes straight.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Rental of banquet hall = $250

One time charge for meal = $7 per plate

x = the number of people who attend.

Part a: The equation that represents the total cost C

Since there are x people in the banquet

So, number of plates = x

Thus, Total One time charge for meal = 7x

So Total Cost = Rental of banquet hall + Total One time charge for meal

⇒ C = 250 + 7x

this is the equation that represents the total cost C

Part b: The equation that represents the average cost A per person

Putting x = 1 in the above equation of total cost we get,

A = 250 + 7 = 257

this is the equation that represents the average cost A per person

Part c: The estimate number of people who must attend before the average cost drops to $15 per meal

From the graph it is seen that there are 25 people who must attend before the average cost drops to $15 per meal.

Part d: what happens to the average cost as the number of people who attend increases.

The average cost keeps on decreasing exponentially and then becomes straight.

The total surface area of the pyramid 806.12 [tex]m^{2}[/tex].

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

Side (s) = 12

Altitude (h) = 6

Area = 3√3/2*s² + 3*s*√(h²+3s²/4)

Area = 3√3/2*(12)² + 3*(12)*√[6²+3(12)²/4]

Area = 806.12 [tex]m^{2}[/tex]

A 3D object's surface area is the entire area that all of its faces cover. For instance, the surface area of a cube is its surface area if we need to determine how much paint is needed to paint it.  

Area of a square is equal to the sum of the lengths of its sides, where an is a square side.

The surface area of a three-dimensional shape refers to the amount of open space that it occupies. A solid shape's volume is the amount of space it takes up.

Answer:

27.25 feet long

Explanation and Check part below

Hope this helps :)

Step-by-step explanation:

The area is 599.5 square feet and it is 22 feet wide. So in order to find the area we have to multiply the width (22 feet wide) and the legth (unknow number which will stand for "x"). Since we area multiplying the width and legth we need to do the inverse operation which is dividing. We didvide the area 599.5 by the width 22 to get 27.25 feet long.

22x = 599.5

----- -------- <------ Fraction bar/divide

22 22

x = 27.25

Check:

When a number is next to parenthesis it means to multiply the 2 numbers.

22 (27.25) = 599.5

599.5 = 599.5

True statement.

The equation of a line is ax + by = c.

full co-ordinate of the point, in terms of a, b, c, d is (d,(c-ad)/b)

equation of a line is ax + by = c

The phrase equation and its cognates in other languages can also have subtly extraordinary meanings; as an example, in French an équation is described as containing one or more variables, even as in English, any well-shaped components together with two expressions related with an equals sign is an equation.

fixing an equation containing variables includes figuring out which values of the variables make the equality real.

The variables for which the equation must be solved are also referred to as unknowns, and the values of the unknowns that satisfy the equality are referred to as answers of the equation.

Answer:

Step-by-step explanation:

the correct answer would be  -5/-1=|6x|

The absolute value equation for each of the graphs are |x + 3| = 2 and |x - 4| = 1 respectively.

An equation is an expression that shows the relationship between two or more numbers and variables.

An inequality shows the non equal comparison of numbers and variables.

A) For the inequality shown, the midpoint is [(-1) + (-5)]/2 = -3. The distance from each of the endpoint to the midpoint is 2 units (i.e. from -1 to -3 or from -5 to -3). Hence:

Absolute inequality is:

|x - midpoint| = distance from endpoint to midpoint

This gives:

|x - (-3)| = 2

|x + 3| = 2

B) For the inequality shown, the midpoint is [3 + 5]/2 = 4. The distance from each of the endpoint to the midpoint is 1 units (i.e. from 3 to 4 or from 5 to 4). Hence:

Absolute inequality is:

|x - midpoint| = distance from endpoint to midpoint

This gives:

|x - 4| = 1

Answer:

x=7, y=11

Step-by-step explanation:

Using simultaneous equations we can sub y in equation 1 into equation 2.

Equation 1. y=2x-3

Equation 2. x+y=18

Since y=2x-3 we can replace it so that

2'. x+2x-3=18

Now simplify

= 3x-3=18

Add 3 onto both sides to undo the subtraction of 3 so that,

3x=21

Now divide both sides by three to undo the multiplication of 3 so that,

x=7

Now sub in x (which is 7) into one of the equations to find y

7+y=18

To undo the five, subtract 7 from both sides so that

y=11

The measure of each of the small arcs of the circled glass stained window is 45°.

Congruent in circle:

Circles having the same radii are said to be congruent of one another.

For example,

When two circles are congruent, we can also say that they have the same area and circumference. Thus they can also be said to be equal circles.

Given,

In the stained glass window design, all of the small arcs around the circle are congruent. Suppose the center of the circle is point O.

Here we need to find the measure of each of the small arcs.

We know that.

Congruent circles can be defined as circles which are having the same or equal radii.

So, based on this the circle we need to divided it as equal radius arcs.

We know that, the measurement of the full circle is 360°.

So, here we have to divide it by 8.

Then we have each arc as,
