The area of the circle is 254. 502 square units

The formula for area of a circle is expressed as;

Area = πr²

Where;

r is the radius of a circle

Note that the radius of a circle with an inscribed triangle is expressed as;

Radius = ABC/4A

Where;

A, B and C are the sides of the inscribed triangle

Radius = 6 × 6 × 6 / 4(6)

Radius = 216/ 24

Radius = 9 units

Now, substitute the value of the radius into the formula

Area = 3. 142 × (9)²

Area = 3. 142 × 81

Area = 254. 502 square units

Thus, the area of the circle is 254. 502 square units

Step-by-step explanation:

Equation of the horizontal line through the given point is: y = -13.

Equation of the vertical line through the given point is: x = 13.

The equation of a vertical line is expressed as, x = b, where b is the constant representing the point where the line intercepts the x-axis. The line is parallel to the y-axis.

On the other hand, the horizontal line intersects the y-axis at a point, b, and it is parallel to the x-axis. It is written as y = b.

Given the point, (13, -13), we have the following:

Equation of the horizontal line through the given point is: y = -13.

Answer:  y = -4x + 6

Step-by-step explanation:

supposing m1 is the gradient of the line  for whose equation  we want to find

m1  * m2 =-1  for perpendicular lines

if m1 = 1/4

meaning m2 = -4

m2= -4 at point (2,-2)

we can get value of constant  c

y = mx =c

-2 = (-4)(2) +c

c = 6

substituting c and m2 in gen eqn of line : y =mx +c

y = -4x + 6

Step-by-step explanation:

The sum of the polynomials in the equation is 3x² - 2x - 3

Step-by-step explanation:

(3 - 4x + 8x²) + (-6 + 2x - 5x²)

Distribute the positive sign to (-6 + 2x - 5x²). So all of these terms will stay the same and maintain their original signs.

3 - 4x + 8x² - 6 + 2x - 5x²

Combine like terms.

- 3 - 2x + 3x²

Now put the equation in standard form. This means that the exponential numbers will be ordered in descending order.

According to the percentage, Stephen played this week is 24.2 minutes.

According to the statement

We have to find that the number of minutes has he played this week.

So, For this purpose, we know that the

A percentage is a number or ratio expressed as a fraction of 100.

From the given information:

Stephen has logged 220 minutes of game play today. His dashboard says that today's game time represents 11% of his game play for the week.

Then

Time of logged of game play = 220 minutes

Today's game time = 11% of his game play

Then

The minutes he played game in a week = 11% of 220 minutes

The minutes he played game in a week = 11/100*220

The minutes he played game in a week = 0.11*220

The minutes he played game in a week = 24.2 minutes.

So, According to the percentage, Stephen played this week is 24.2 minutes.

Answer:

15.  x-intercept = (-4, 0)

      y-intercept = (0, 2.5)

16.  A. An infinite number of solutions.

Step-by-step explanation:

The x-intercepts are where the line crosses the x-axis, i.e. when y = 0.

The y-intercepts are where the line crosses the y-axis, i.e. when x = 0.

Given equation:

[tex]5x-8y=-20[/tex]

Substitute y = 0 into the given equation to find the x-intercept:

[tex]\begin{aligned}y=0 \implies 5x-8(0) &=-20\\5x & = -20\\x & = \dfrac{-20}{5}\\x & = -4\end{aligned}[/tex]

Therefore, the x-intercept is (-4, 0).

Substitute x = 0 into the given equation to find the y-intercept:

[tex]\begin{aligned}x=0 \implies 5(0)-8y &=-20\\-8y & = -20\\y & = \dfrac{-20}{-8}\\y & =2.5\end{aligned}[/tex]

Therefore, the y-intercept is (0, 2.5).

Given system of equations:

[tex]\begin{cases}3x-2y=14\\6x=4y+28\end{cases}[/tex]

Multiply the first equation by 2:

[tex]\implies 2(3x-2y)=2(14)[/tex]

[tex]\implies 6x-4y=28[/tex]

Add 4y to both sides:

[tex]\implies 6x-4y+4y=4y+28[/tex]

[tex]\implies 6x=4y+28[/tex]

Therefore, the two equations are the same.  

A system of linear equations has an infinite number of solutions when the graphs are the exact same line.

9(0.11)= 0.99

12.62-0.99= 11.63

B ∪ A is the relationship between Set A and Set B.

We have two sets A and B.

We have to determine the relationship between set A and set B if A intersects B = B.

A set is a collection of elements, numbers or objects, represented within the curly brackets { }.

According to the question -

A ∩ B = B.

This means that the intersection of set A and set B is equal to B. This means common elements in both the set are same as the elements of set B. This can only happen when -

B ∪ A → B is the subset of A.

Hence, B ∪ A is the relationship between Set A and Set B.

In a certain city, if the cost of availing drinking water service is $62.44, and we have to pay an additional $6.35 for every m³ of water consumed, then the algebraic expression that describes the total to be paid (T) on a consumption of (C) m³ of water will be [T = (6.35C + 62.44)].

As per the question statement, in a certain city, the cost of availing drinking water service is $62.44, and we have to pay an additional $6.35 for every m³ of water consumed.

We are required to determine an algebraic expression that can describe the total amount to be paid (T) for a consumption of (C) m³ of drinking water.

Here, if we suppose that 1 m³ of drinking water is consumed, then total amount to be paid = [tex][(6.35*1)+62.44][/tex]

Similarly, if we suppose that 2 m³ of drinking water is consumed, then total amount to be paid = [tex][(6.35*2)+62.44][/tex]

Thus, on consumption of "C" m³ of drinking water is consumed, total amount to be paid [tex][T=(6.35*C)+62.44][/tex]
