Answer:

[tex]Area = 476m^2[/tex]

Step-by-step explanation:

Given

See attachment

Required

The uncovered area

First, calculate the area of the rectangle

[tex]Area = Length * Width[/tex]

From the attachment

[tex]Length = 25m[/tex] and [tex]Width = 20m[/tex]

So:

[tex]Area = 25m * 20m[/tex]

[tex]Area = 500m^2[/tex]

The area of the triangle is:

[tex]Area = \frac{1}{2} * Base * Height[/tex]

From the attachment

[tex]Base = 8m[/tex]

[tex]Height = 6m[/tex]

So:

[tex]Area = \frac{1}{2} * 8m * 6m[/tex]

[tex]Area = \frac{1}{2} * 48m^2[/tex]

[tex]Area = 24m^2[/tex]

The uncovered area is:

[tex]Area = 500m^2 - 24m^2[/tex]

[tex]Area = 476m^2[/tex]

Answer:

25(x+2)(x−2)

Step-by-step explanation:

The solution is A = 25 ( x - 2 ) ( x - 2 )

The equation to the expression is given as A = 25 ( x - 2 ) ( x - 2 )

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

A = 25x² - 100   be equation (1)

On simplifying the equation , we get

Taking 25 as the common factor of the equation , we get

A = 25 ( x² - 4 )

Now , ( x² - a² ) = ( x + a ) ( x - a )

So , the value of ( x² - 4 ) can be simplified as

A = 25 ( x + 2 ) ( x - 2 )

Therefore , the value of A is 25 ( x + 2 ) ( x - 2 )

Hence , the equation is A = 25 ( x + 2 ) ( x - 2 )

Step-by-step explanation:

edge

The region outside the circle is under the consideration. Then the correct option is B.

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x – h)² + (y – k)² = r²

The inequality equation of the graph is given below.

(x – 3)² + (y + 4)² > 36

(x – 3)² + (y + 4)² > 6²

From the equation, the radius of the circle will be 6 units and the center of the circle will be (3, –4).

The region outside the circle is under the consideration.

Then the correct option is B.

Answer:  [tex]y = \frac{1}{2}x+3[/tex]

This is the same as writing y = (1/2)x + 3

========================================================

Explanation:

Two points on the blue line are (0,3) and (2,4)

To go from the left point to the right, we go up 1 and over to the right 2.

Slope = rise/run = 1/2

Or we can use the slope formula to get the same value

m = (y2-y1)/(x2-x1)

m = (4-3)/(2-0)

m = 1/2

The y intercept is b = 3 because this is the location on the vertical y axis where the blue line crosses. This is the location (0,3).

With m = 1/2 and b = 3, we go from y = mx+b to y = (1/2)x + 3

On a piece of paper, that would look like the equation [tex]y = \frac{1}{2}x + 3[/tex]

Answer:

x=9

Step-by-step explanation:

The expression is for the interior angle of the hexagon; one interior angle is equal to .

Since an interior angle of a hexagon measures 120°, we have the equality

.

Now it is just a matter of solving for  

11x=120-21

11x=99

x=99/11

x=9

The value of {x} for the hexagon shown is 9.

A hexagon is a polygon with 6 equal sides. The perimeter of a hexagon is the sum of all the six lengths. The measure of the interior angle of a hexagon is 120 degrees.

Given is to find the value of {x} in the Hexagon shown below.

The measure of the internal angle of a hexagon is 120 degrees. So, we can write -

(11x + 21) = 120

11x = 120 - 21

11x = 99

x = 9

Therefore, the value of {x} for the hexagon shown is 9.

Answer: a=-3.4

Step-by-step explanation: you mean solve for a:)

-2a+7-3(-9-4a)=0        We would have to equal this equation to 0

-2a+7+27+12a=0         We multiply the -3 with the parentheses

10a+34=0                     Add the like terms, and subtract 34 from both sides

10a=-34                        Then divide both sides by 10

a=-3.4

Answer: A. The amplitude is 3.

Step-by-step explanation:

Period of a sine function is [tex]2\pi.[/tex]

Since [tex]-1\leq \sin x \leq 1[/tex]

[tex]\Rightarrow\ -3\leq -3\sin x\leq 3\\\\\Rightarrow\ -3+2\leq -3\sin x+2\leq 3+2\\\\\Rightarrow\ -1\leq -3\sin x+2\leq 5[/tex]

i.e. Range is [-1,5]

Amplitude = 3 [coefficient of sin x]

Answer: The value of (f+g)(2) = -1

Step-by-step explanation:

Given: f(2)=-14 and g(2)=13

To find: (f+g)(2)

Addition of two functions:

(f+g)(x) = f(x)+g(x)

Then, (f+g)(2) = f(2)+g(2)

(f+g)(2)  = -14+13  [given]

(f+g)(2)  = -1

Therefore , the value of (f+g)(2) = -1
