The value of c is 4.

Here, we are given an equation

2c - 12c + 13c = 12

Since, all the terms on the left hand side have a c in them, we can take it common outside the bracket as follows-

c (2 - 12 + 13) = 12

or c (2 + 13 - 12) = 12

Firstly, we add the positive terms in the bracket which will give us

c (15 -12) = 12

Now, we subtract 12 from 15 to get

c (3) = 12

or 3c = 12

Dividing by 3 on both sides we get

c = 12/3

c = 4

Thus, the value of c is 4.

g(x) = 3√(x-5) -1

The process of altering a graph to produce a different version of the preceding graph is known as graph transformation. The graphs can be moved about the x-y plane or translated. They may also be stretched, or they may undergo a mix of these changes.

Horizontal stretching: It means the graph is elongated or shrink in x direction.

Vertical stretching : It means the graph is elongated or shrink in y direction

Vertical translation : It means moving the base of the graph in y direction

Horizontal translation : It means moving the base of the graph in x direction

According to rules of transformation f(x)+c shift c units up and f(x)-c shift c units down.

Therefore, in order to  move the graph down 1 units, we need to subtract given function by 1 , we get

g(x) = 3√x -1

According to rules of transformation f(x+c) shift c units left and f(x-c ) shift c units right.

Therefore, in order to  move the graph left by 5 units, we need to add given function by 5 , we get

g(x) = 3√(x-5) -1

The domain of the function given on the graph is basically all numbers which are real and greater than or equal to -3.

Given a graph of a function.

We are required to choose the correct domain of the function from the options.

Function is basically a relationship between two or more variables that are expressed in equal to form. The values that we enter in the function are known as part of domain of that function and the values that we get from the function are known as part of range of that function.

Because the lowest point on x axis on which the curve starts is -3 and it continuously increases, so the domain of the function given on the graph is basically all real numbers which are greater than or equal to -3.

Hence the domain of the function given on the graph is all real numbers which are greater than or equal to -3.

The area and the perimeter are 18x^2 + 63x and 22x + 14

The given parameters are

Length = 9x

Width = 2x + 7

The area is calculated as

Area = Length * Width

So, we have

Area = 9x * (2x + 7)

This gives

Area = 18x^2 + 63x

The perimeter is calculated as

P = 2 * (Length + Width)

So, we have

P = 2 * (9x + 2x + 7)

Evaluate

P = 22x + 14

Using proportions and multiplication, it is found that the door's height is 4 times greater than the desk's height.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The ratio between two amounts a and b is the proportion of a to b, that is, the division of a by b.

Using measures of variability, it is found that:

a. The situations with constant measures involve constant distributions, such as the number of snow days in Miami each year.

b. The situations with different measures involve constant distributions, such as the number of snow days in Buffalo each year.

There are three measures of variability in a data-set: the range, the standard deviation and the variance.

The range is given by the difference between the maximum value and the minimum value of a data-set.

The standard deviation and the variance are described as follows:

Uniform(constants) data-sets will have similar measures. One example is the number of snow days in Miami each year, which is always of 0, hence the three measures will be of 0.

More disperse data-set will have different measures. Taking the city of Buffalo, in New York, as an example. On average, it should have 40 days of snow each winter, but on colder winters it can have 60 and warmer winters it can have 20. Hence the distribution with the number of snow days in Buffalo over a period of 20 years will have different range, standard deviation and variances.
