The equation of the circle is given by (C) (x-3)² + (y + 4)² = 9

All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant. The radius of a circle is the separation between any point on the circle and its center.

The equation of the circle in the general form is given by the

(x-a)²+(y-b)²=r²

Where (a,b) is the co-ordinates of the center of the circle and the radius is r.

Now the center of the circle is given at (3,-4) and the radius is r.

We know that the general equation of a circle is  [tex]{\displaystyle (x-a)^{2}+(y-b)^{2}=r^{2}}[/tex]

Substituting the values in the equation we get:

(x-3)²+(y-(-4))²=(3)²

or, (x-3)²+(y+4)²=9

Hence the equation of the circle is (x-3)² + (y + 4)² = 9.

Step-by-step explanation:

From the following compound inequalities, all the compound inequalities have a solution.

What is compound inequality?

A compound inequality is a type of inequality that comprises two basic inequalities.

From the given information, we have:

3x-7 ≤ 5x + 5 and -4x +8 < 5x - 1

-2x+9>4x+3 and-8x-9 < -7x-3

-2(x-9) < 3(x+4) and -4(x-1) > -5(x-2)

3x+1 < 5x+7 and -2x+5 ≤ -5x -10

To determine the compound inequality with no solution, we need to solve each of the inequalities.

1.

3x-7 ≤ 5x + 5 and -4x +8 < 5x - 1

Collect like terms

-7-5 ≤ 5x-3x and 8+1 < 5x+4x

-12 ≤ 2x and 9 <9x

x ≥ -6 and x > 1 (has a solution)

2. -2x+9>4x+3 and-8x-9 < -7x-3

Collect like terms

9-3 > 4x+2x and -9+3 < 8x-7x

6 > 6x and -6 < x

x< 1 and x < -6 (has a solution)

3.

-2(x-9) < 3(x+4) and -4(x-1) > -5(x-2)

Open brackets

= -2x +18 < 3x + 12 and -4x + 4 > -5x +10

Collect like terms

= 2x + 3x > 18 - 12 and 5x-4x > 10 -4

=  5x < 6 and x > 6

= x > 6/5 and x > 6  (has a solution)

4.

3x+1 < 5x+7 and -2x+5 ≤ -5x -10

1-7 < 5x-3x and 5x -2x ≤ -10 +2

-6 < 2x and 3x ≤ -8

x > -3 and x ≤ -8/3 ( has a solution)

Therefore, no compound inequalities has no solution.

Answer: 8+7

The | | symbol means how far it is from 0 on the number line. -7 is still only 7 away from 0. Now, if you have -|8|, you apply that - to the 8, so then it's -8.

Solving a linear equation, we will see that 109 attendees did not visit the concession stand.

How to find the number of attendees who did not visit the concession stand?

First, we know that the total number of surveyed people is 680.

Of these 680, we know that:

Now, the 3 numbers above should add up to the total number of surveyed people.

527 + 44 + x = 680

Solving that linear equation for x:

x = 680 - 527 - 44 = 109

We conclude that the number of attendees who did not visit the concession stand is 109.

The direct variation is -27/7.

y=27/7 when x= 7

Y= -9 when x = 3 and y varies directly with x which can be written as y directly proportional to x.

[tex]x_{1} /x_{2}[/tex] = [tex]y_{1} /y_{2}[/tex]

3/7 = -9/y2

y2 = - 27/7

A variation is a connection between a set of values for one variable and a different set of values. If m is a nonzero constant and b = 0, the equation y = mx + b yields the function y = mx (often written y = kx), which is known as a direct variation.

The calculus of variations is a branch of mathematical analysis which finds maxima and minima of functionals: mappings from a set of functions to the real numbers. Variations are minor changes in functions and functionals.

The maximum profit the company can make given these constraints is; $1360

We are given that;

Its dealers demand at least 30 skateboards per day and 20 pairs of in-line skates per day. The factory can make at most 60 skateboards and 40 pairs of in-line skates per day. The total number of skateboards and pairs of in-line skates cannot exceed 90. The profit of each skateboard is $12 and the profit on each pair of in-line skates is $19

Thus, the inequalities are as follows;

Let x represent number of skateboards

Let y represent in-line skates

Thus;

x ≥ 30

y ≥ 20

x ≤ 60

y ≤ 40

x + y ≤ 90

y ≤  -x + 90

f(x, y) = 12x + 19y

At (30, 20), f(30, 20) = 12(30) + 19(20) = $740

At (30, 40), f(30, 40) = 12(30) + 19(40) = $1120

At (50, 40), f(50, 40) = 12(50) + 19(40) = $1360

At (60, 20), f(60, 20) = 12(60) + 19(20) = $1100

At (60, 30), f(60,30) =  12(60) + 19(30) = $1290

Thus, the maximum profit the company can make given these constraints is; $1360

The number that makes the statement is -5.8 + 6.8 = 1 > 0 so, the statement is -5.8 + 6.8 = a positive number is true statement.

The number that makes the statement is,

Based on given conditions , formulate,

-5.8+ _     = a positive number

Let us assume,

We can take positive number is '1'

Then, we can write,

⇒ 1 - (-5.8)

We can negative sign and negative signs are shows to positive sign,

⇒ 1 + 5.8

We can sum or difference in the product,

⇒ 6.8

Hence,

⇒ -5.8 + 6.8

⇒ 1

So, 1 is positive number.

Then,  -5.8 + 6.8 = 1 > 0

Therefore, The number that makes the statement is -5.8 + 6.8 = 1 > 0 so,

-5.8 + 6.8 = a positive number.

Sorry If I'm Wrong

the correct option is D:

" The inverse relation must pass the vertical line test."

Remember that a relation is only a function if each value in the domain is only mapped into a single value in the range.

All functions need to pass what is called the "vertical line test" this means that if you draw a vertical line on the graph of the function, the vertical line can intersect the graph at most one time. If the vertical line intercepts the graph two or more times, then it is not a function.

From this we conclude that the correct option is D:

" The inverse relation must pass the vertical line test."
