We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.
What is the area?The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.
The area of the composite figure is equal to the sum of area 1, area 2, and area 3
Area 1 - triangle
Area 2 - rectangle
Area 3 - semicircle
We can decompose the composite figure into a triangle, a rectangle, and a semicircle in order to find the area of the composite figure.

A container in the shape of a rectangular prism has a height of 2 feet. Its length is four
times its width. The volume of the container is 200 cubic feet. Find the length and width of
the container.
Answer:
length = 20 feet and width = 5 feet
Step-by-step explanation:
Volume is equal to volume = height * width * length. The questions tells us the total volume is 200 cubic feet and that the lenght is equal to length = 4w. Set up the equation 4w * w * 2 = 200 cubic feet. Multiply to get 8w^2 = 200 and solve for w.

Answer:
x = 7y = 97°z = 19Step-by-step explanation:
The markings on the figure show this to be a parallelogram. That means opposite sides are congruent. Because the sides are parallel, "alternate interior" angles are also congruent.
__
Angle y forms a linear pair with the one marked 83°, so is supplementary to it:
y = 180°-83° = 97°
__
The angle marked y is an exterior angle to the triangle containing the angle marked (7x -5)°. As such, it is equal to the sum of the remote interior angles, the one marked (7x -5)° and the unmarked one that is congruent to (3x +32)°.
(7x -5) +(3x +32) = 97 . . . . . angle relations in the left-side triangle
10x +27 = 97 . . . . . . . collect terms
10x = 70 . . . . . . . . subtract 27
x = 7 . . . . . . . . divide by 10
__
The side marked Z is congruent to the opposite parallel side, so ...
z = 19
__
The missing measures are ...
x = 7y = 97°z = 19_____
Additional comment
You can also find the value of y by adding up the interior angles of the right-side triangle. The one not shown there is "alternate interior" to the one marked (7x -5)°, hence has the same measure. This gives ...
(7x -5) +(3x +32) +83 = 180
Subtracting 83° from both sides gives the equation we used above.
A firm is considering projects s and l, whose cash flows are shown below. These projects are mutually exclusive, equally risky, and not repeatable. The ceo wants to use the irr criterion, while the cfo favors the npv method. You were hired to advise the firm on the best procedure. If the wrong decision criterion is used, how much potential value would the firm lose?.
If the wrong discion criterion is used, the potential lose in value for the firm is $209.07.
What is the correct decision criterion?
The correct decision criterion is the net present value. Net present value is the present value of after-tax cash flows from an investment less the amount invested. The internal rate of return is the discount rate that equates the after-tax cash flows from an investment to the amount invested
What is the loss in value if the wrong decision criteria is used?The net present vaue and the internal rate of return can be calculated using the financial calcuator.
Project S:
Cash flow in year 0 = $-1025Cash flow each year from year 1 to 4 = $380I = 6%
NPV = 291.74
IRR = 17.86%
Project I:
Cash flow in year 0 = $-2150
Cash flow each year from year 1 to 4 = 765
I = 6%
NPV = 500.81
IRR = 15.78%
If the wrong criteria is used, Project S would be chosen.
Loss in value = 500.81 - 291.74 = $209.07.
Here are the cash flows used:
WACC: 6.00%

Find the outer perimeter of this figure. Round
your answer to the nearest hundredth. Use
3.14 to approximate pi.
P = [ ? ] ft.
Answer:
61.90 ft
Step-by-step explanation:
Perimeter: the boundary that surrounds a shape
1) Find the perimeter of the semicircle using this formula: [tex]\frac{1}{2} *2\pi r[/tex], where [tex]r[/tex] is the radius, and π is 3.14 (according to the question).
1.1) We need to find the radius first.
Radius = Diameter ÷ 2
So, 10 ÷ 2 = 5
1.2) Input the values into the semicircle formula.
[tex]\frac{1}{2} *2(3.14)(5)[/tex]
1.3) solve for the perimeter of the semicircle.
[tex]\frac{1}{2} *31.4[/tex]
= 15.7
2) Find the perimeter of the triangle and the rectangle.
= [tex]6 + 12.2 + 14 + 14[/tex]
= 46.2
3) Add them.
= [tex]46.2 + 15.7[/tex]

How to determine the domain of the function of the height of the ball in function
All functions are relations in which there is no value of the domain related to more than one value of the range, functions in explicit form related the variable of the range in terms of the variable of the domain.
Based on the information shown in the graph, the domain is represented by the set of values of the time, that is, the horizontal axis, and the range is represented by the set of values of the height, that is, the vertical axis.
Hence, the domain is represented by the set of values of the time, that is, the horizontal axis, and the domain of the given function is represented by t ∈ [0, 4.5].
