Answer:

D. 9

Step-by-step explanation:

The expression that represents the volume of the composite figure is (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)

The volume of the composite figure will be the sum of the volume of the prism and the volume of the pyramid.

The Volume of the prism = Area of the base * height of the prism

Area of the base = 1/2*4.4 *2

Height of the prism =5

So, the Volume of the prism =  (1/2)* (4.4)*(2)*(5)

The volume of the pyramid = 1/3 *(area of the base) * (height of the pyramid)

Area of the base of the pyramid =  1/2*4.4 *2

Height of the pyramid =3.9

So, the volume of the pyramid = (1/3)* (1/2)*(4.4)*(2)*(3.9)

So, total volume =  (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)

Hence, the expression that represents the volume of the composite figure is (1/2)* (4.4)*(2)*(5) + (1/3)* (1/2)*(4.4)*(2)*(3.9)

Answer:

1. ( w + 7 ) ( w + 2 )

2. ( x - 9 ) ( x - 5 )

Step-by-step explanation:

1.

w² + 9w + 14

= w² + 7w + 2w + 14

= w ( w + 7 ) + 2 ( w + 7 )

= ( w + 7 ) ( w + 2 )

Hence, factorised.

2.

x² - 14x + 45

= x² - 5x - 9x + 45

= x ( x - 5 ) - 9 ( x - 5 )

= ( x - 9 ) ( x - 5 )

Hence, factorised.

The equation of the area of the rectangle is w(2w + 5) = 50. Then the correct option is C.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A rectangle’s length is 5 inches more than twice its width. its area is 50 square inches.

Let the width of the rectangle be w, then the length of the rectangle will be (2w + 5).

Then the area of the rectangle is given as

Area = l × w

Then we have

w(2w + 5) = 50

Answer:

7.2

Step-by-step explanation:

We know that the radius is always the same throughout the entire circle. That is, any line going from the center of the circle to the edges = radius. In this problem, radius = 20.9 and so does the other 4 lines going from the center of the circle to the edge.

Since there is a right angle, we know that both triangles are right triangles where hypotenuse, c = 20.9 and b = 19.6. To solve for x, use pythagorean theorem:

a² + b² = c²

x² + 19.6² = 20.9²

x² + 384.16 = 436.81

x = √(436.81 - 384.16)

x = √52.65

x ≈ 7.256

1.  What would you use to graph the solution to an equation with one variable?      

I picked an example equation, y=2x+3, to demonstrate the impacts of changing condions.  It is the blue line.  I'm not sure how to answer the quesion "What would you use . . .", but my response would be "I would use DESMOS to graph the solution."  It is free, efficient, and very flexible.  It can handle multiple equations and a variety of functions.

2.  What would happen to the graph if all the y-values were increased by 1?

I added 1 to the right side of the equation to increase all the y values by 1.  It is the black line.  All points are raised by 1.

3.  What would happen to the graph if all the x-values were increased by 1?

I added +1 to each x value, shown as the red line.  All points are increased by 2 over the original line.

4.  What would happen to the graph if all the y-values were multiplied by 2 or by 1/2?

See Increeases2, attached.  The slopes of the lines are doubled when the y values are doubled, and decreased by (1/2) when they are multiplied by (1/2).  The y intercepts are also doubled or halved, respectively.

The expression that represents the volume of the composite figure is (8*6*4)+ 1/3 * (8*6*6).

The volume of the composite figure will be the sum of the volume of the cube and the volume of the pyramid.

Volume of the cube = length*breadth*height

So, the volume of the cube = 8*6*4

The volume of the pyramid = 1/3 *(area of the base) * (height of the pyramid)

Area of the base of the pyramid = 8*6

Height of the pyramid = total height - height of the cube

Height of the pyramid = 10-4 =6

So, the volume of the pyramid = 1/3 * 8*6*6

So, total volume = (8*6*4)+ 1/3 * (8*6*6)

Hence, the expression that represents the volume of the composite figure is (8*6*4)+ 1/3 * (8*6*6).

Step-by-step explanation:

Rate of Changes:

[tex]\displaystyle \large{\dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

Pick two values of x and y from the given table:

Therefore:

[tex]\displaystyle \large{\dfrac{\Delta y}{\Delta x}=\dfrac{5-13}{1-(-1)}}\\\displaystyle \large{\dfrac{\Delta y}{\Delta x}=\dfrac{-8}{1+1}}\\\displaystyle \large{\dfrac{\Delta y}{\Delta x}=\dfrac{-8}{2}}\\\displaystyle \large{\dfrac{\Delta y}{\Delta x}=-4}[/tex]

Therefore, rate of change is -4

By taking the quotient between the number of calls and the number of phone numbers, we see that each number was called 76 times.

We need to find the quotient between the total number of calls and the total number of phone numbers called.

We know that the total number of calls is 836, while it is equally distributed between 11 phone numbers.

The number of times that each of these numbers was called is given by:

N = 836/11 = 76

This means that he calls each number 76 times.

The points on the red arc are points A and B

The measure of the red arc is 75 degrees

From the complete question, we have:

Angle DCE = 75 degrees

By vertical angles theorem,

Angle ACB = Angle DCE = 75 degrees

So, we have:

Angle ACB = 75 degrees

The measure of the red arc is the same as the measure of the angle ACB.

So, we have:

Red arc = 75 degrees

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Your homeowners policy has a premium of $150, a deductible of $5000, and a limit of $300,000.

And,  Your home suffers $500,000 in damages.

Now,

Since, Homeowners policy has a premium of $150, So we can pay the amount = 12 x 150

           = $1,800

And,  Homeowners policy has a deductible of $5000.

Then, The remain amount = $500,000 - $5,000

                                        = $495,000

Since, The limit of the policy = $300,000

Hence, The remain amount = $495,000 - $300,000

                                           = $195,000

After including the deductible amount we get;

Deductible amount = $195,000 + $5,000

                             = $200,000

Thus, He will pay $200,000.
