Answer:
112 cm (red, 4)
Step-by-step explanation:
length = b
width = a
b = 7a
42 = b - a
42 = 7a - a
42 = 6a
a = 7 => b = 7a b = 7*7 = 49
Perimeter = 2*(a+b)
= 2*(7+49)
= 2*(56)
= 112 cm

Suppose the function E(c) represents the earnings of a volleyball team from selling c cupcakes. They are selling each cupcake for $2. They only bought enough supplies to make 100 cupcakes. Describe an appropriate domain and range of this function using interval notation.
Answers
Using domain and range concepts, it is found that:
An appropriate domain for the function is: [tex]c \in [0,100][/tex]An appropriate range for the function is [tex]E \in [0,200][/tex].------------------------------
The domain of a function are the values that the input can assume.The range of a function are the values that the output can assume.------------------------------
The function E(c) represents the earnings of selling c cupcakes.The input is the number of cupcakes sold c.The output is the earnings E.------------------------------
They have enough supplies to make 100 cupcakes, thus, at most 100 cupcakes can be sold, meaning that an appropriate domain for the function is: [tex]c \in [0,100][/tex]If no cupcakes are sold, the earnings will be of $0. If all 100 cupcakes are sold, the earnings will be of $200, as each is sold for $2, meaning that an appropriate range for the function is [tex]E \in [0,200][/tex].A similar problem is given at https://brainly.com/question/2145599

What is graph transformation?
The technique of altering an existing graph or graphed equation to create a different version of the following graph is known as graph transformation. In particular, the change of algebraic equations, it is a typical kind of algebraic problem.
Graphs can be extended, rotated, inverted, or any combination of these transformations; they can also be translated or moved along the xyxy plane. The formulas "move the function f(x)f(x) by cc units in some direction," "stretch the function f(x)f(x) by cc units," and "rotate the function f(x)f(x) by xx units about the xx-, yy-, or zz-axis" are frequently used in mathematical issues. In every instance, the transformation has specific, calculable effects on the underlying function.
Since the triangle ABC and DEF is similar
So we can write,
DE/BC=EF/AB=FD/CA
scale factor =Length of CA/length of DF
=6/3
=2:1
Reflected at y axis i.e x=0
and raised by 2 units.
Therefore, In the similarity transformation of ΔACB to ΔEFD, ΔACB was dilated by a scale factor of 2, reflected across the y-axis, and moved through the translation 2 units

You are going to have a swimming pool put your back yard this summer. The dimensions of the pool are going to be 15 ft by 30 ft. There is going to be a concrete walkway around the outside of the pool, but they are not sure how wide it will be. The design of the pool, including the walkway, is shown below.
Answers
The perimeter of a shape is the sum of the all visible side lengths of the shape. The perimeter of the pool including the walkway is 90 + 8x
Given that:
[tex]Length = 15[/tex]
[tex]Width = 30[/tex]
Let the width of the walkway be x.
The dimension of the pool including the walkway is calculated by adding the dimension of the pool to the width of the walkway (on both sides):
So, we have:
[tex]Length = 15 + x + x[/tex]
[tex]Length = 15 + 2x[/tex]
[tex]Width = 30 + x + x[/tex]
[tex]Width = 30 + 2x[/tex]
The perimeter (P) of the walkway is then calculated using:
[tex]P = 2 \times (Length + Width)[/tex]
This gives:
[tex]P = 2 \times (15 + 2x + 30 + 2x)[/tex]
Collect like terms
[tex]P = 2 \times (15 + 30+ 2x + 2x)[/tex]
[tex]P = 2 \times (45+ 4x)[/tex]
Open brackets
[tex]P = 2 \times 45+ 2 \times 4x[/tex]
[tex]P = 90+ 8x[/tex]
Hence, the perimeter of the pool including the walkway is 90 + 8x (see attachment)
