find the area of the Shaded region in square centimeters ​

Answer:

9

Step-by-step explanation:

that's because angle B is twice angle A in which they add up to 180 because they are supplementary angles

20x=180

divide both sides by 20

in which

x=9

Answer:

The y-intercept is y = -$150

Step-by-step explanation:

We know that:

Each necklace is sold for $8.

The total cost for Michelle is $150.

The profit equation is:

Profit = Revenue - Cost.

We already know that Cost = $150

The revenue will depend on x, the number of necklaces sold, so if each one costs $8, and she sells x of them, the revenue is:

Revenue = $8*x

Then the profit, as a function of x, is:

y = P(x) = $8*x - $150

Where y represents the profit.

Now we want to find the y-intercept of the profit equation, where the y-intercept is the y-value when we use x = 0

Then the y-intercept is:

P(0) = $8*0 - $150 = -$150

Also the graph of the equation can be seen below, where you need to remember that x can be any value in [0, 200] and only can be an integer.

So you only need to graph the line between x = 0 and x = 200.

Answer:

y= 327(0.85)^t

Step-by-step explanation:

Given data

Initial Population= 327

Increase= 15%

The model for an exponential function is represented as

y= P(1-r)^t

Substitute

y=327(1-0.15)^t

y= 327(0.85)^t

Answer:

(x+1)²+(y-2)² = 25

Step-by-step explanation:

Standard equation of the circle is expressed as;

(x-a)²+(y-b)² = r²

(a,b) is the center of the circle

r is the radius

Get the radius

r = √(x2-x1)²+(y2-y1)²

r = √(2+1)²+(6-2)²

r = √3²+4²

r = √9+16

r = √25

r = 5

Substitute into the formula

(x-a)²+(y-b)² = r²

a = -1, b = 2, r = 5

(x-(-1))²+(y-2)² = 5²

(x+1)²+(y-2)² = 25

This gives the required equation

Answer: 24 cm²

Step-by-step explanation:

To find the area, first find the width of the rectangle.

Perimeter = (2 * Length) + (2 * Width)

20 = (2 * 6) + (2w)

20 = 12 + 2w

2w = 20 - 12

w = 8/2

w = 4 centimeters

Area = Length * Width

= 6 * 4

= 24 cm²

Answer: X = -12

Step-by-step explanation:  1)  12 + x/4 = 9

                                              2)  12 + x/ 2^2 = 9

                                              3)   x/ 2^2  + 12 = 9  

Answer:

46.05degrees

Step-by-step explanation:

Given the following

Height of tree = 18ft (Opposite)

length of shadow = 25ft (hypotenuse)

Required

Angle of elevation

Sin theta = opp/hyp

Sin x = 18/25

sin x = 0.72

x = arcsin(0.72)

x = 46.05

Hence the angle of elevation of the sun is 46.05degrees

Answer:

length=x-4

Step-by-step explanation:

Answer:

x = 55° and y = 25°

Step-by-step explanation:

Since we have two triangular patios with angles  (x + 5)°, (y + 15)°, and 80° and the second patio has angles, (x + 25)°, 40°, and 60° respectively, and the sum of angles in a triangle is 180, we have that,

(x + 5)° + (y + 15)° + 80° = 180° and

(x + 25)° + 40° + 60° = 180°

Simplifying both expressions, we have

x + 5° + y + 15° + 80° = 180° and

x + 25° + 40° + 60° = 180°

collecting like terms, we have

x  + y + 5° + 15° + 80° = 180° and

x + 25° + 40° + 60° = 180°

Adding the like terms, we have

x  + y + 100° = 180°  and

x + 125° = 180°

So,

x  + y = 180° - 100° and

x = 180° - 125°

Thus,

x  + y = 80°   and

x = 55°  

So, y = 80° - x = 80° - 55° = 25°

So, x = 55° and y = 25°

Answer:

x = 11

Step-by-step explanation:

24+4x=6x+2

substract 2x from both sides 4x-4x and 6x -4x

24 = 2x + 2

Substract 2 from both sides 24-2 and 2-2

22 = 2x

Divide by 2 to both sides 22/2 and 2x/2

x = 11

Look at the explanation

Step-by-step explanation:

From this equation, we know our point slope form: y-4= 1/2(x-4)

From here, we also know our point: (4,4)

Our slope is 1/2

We first plot (4,4) on the graph. Then we graph the slope by moving one space up from (4,4) and moving over two spaces.

Our graph would look something like this:

Answer:

  5000π mm³ ≈ 15,700 mm³

Step-by-step explanation:

The volume of the cylinder is given by the formula ...

  V = πr²h

For the given radius and height, the volume is ...

  V = π(10 mm)²(50 mm) = 5000π mm³

Using 3.14 for π, the volume is ...

  5000(3.14) mm³ = 15,700 mm³

Answer:

( x + 2 )² + ( y - 1 )² = 25

Step-by-step explanation:

Circle equation - ( x - h )² + ( y - k )² = r²

Important notes:

(h,k) = center

r = radius

The first step would be to find the center

( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )

Like stated before ( h , k )  = center point

* replace center point with (-2,1) *

( h , k ) = ( -2 , 1 )

h = -2

k = 1

* plug in the h and k values into the circle equation *

now we have ( x - ( -2) )² + ( y - 1 )²

Now to find the radius

We can find the radius by using the distance formula with the center point and any point on the circle's outline

The point chosen can vary but i chose (3,1)

Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius

3 - (-2)

the two negative signs cancel out

3 + 2 = 5

So the radius equals 5

* plug in the value of the radius into the equation *

Now we have

( x - (-2) )² + ( y - 1 )² = 5²

our final step is to simplify

- (-2) the two negative signs cancel out and it turns into +2

5² = 25

Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

Answer:

x = 1

Step-by-step explanation:

Given

[tex]\frac{2x^2-7x-4}{x^2-5x+4}[/tex] ← factor numerator and denominator

= [tex]\frac{(x-4)(2x+1)}{(x-4)(x-1)}[/tex] ← cancel (x - 4) on numerator/ denominator

= [tex]\frac{2x+1}{x-1}[/tex]

The denominator of the rational expression cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that x cannot be.

x - 1 = 0 ⇒ x = 1 ← excluded value
