The author shows that computer programs make it faster to make changes to blur prints.
A computer program is a set of instructions written in a programming language that a computer is supposed to obey.
Computer programs are one of the intangible components of software, which also includes documentation and other components.The version of a computer program that humans can read is called the source code. Source code must be run by another program because computers can only execute their native machine instructions. Consequently, source code can be transformed into machine instructions using the language's compiler. (Programs written in machine language are translated using an assembler.) The produced file's name is an executable. The language's interpreter may also be used as a backup.Hence it is clear that the author shows that computer programs make it much faster to make changes to blue prints.

a farmer is building a fence to enclose a rectangular area consisting of 2 separate regions. the 4 walls and one additional vertical segment to separate the regions are made up of fencing. if the farmer has 648 feet of fencing what are the dimensions of the region which enclose the maximum area?
The dimensions of the region which enclose the maximum area is a side of 162 feet and vertical segment of 108 feet
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the side parallel to the vertical segment and y represent the other side. If the farmer has 648 feet of fencing, hence:
x + x + y + y + x = 648
3x + 2y = 648
y = 324 - 1.5x
Area (A) = xy
A = xy
A = x(324 - 1.5x)
A = 324x - 1.5x²
The maximum area is at A' = 0, hence:
A' = 324 - 3x
324 - 3x = 0
3x = 324
x = 108 feet
y = 324 - 1.5(108) = 162 feet
x = 108 feet, y = 162 feet

Which term of the arithmetic sequence 7, 3, -1, -5, ... is -385?
99th term of the given arithmetic sequence 7, 3, -1, -5, ... is -385.
We are provided with the arithmetic sequence mentioned below;
7, 3, -1, -5, ................. -385
[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n−1)d
where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term and d is the difference between a term and its previous term.
With the help of provided arithmetic sequence we can write;
[tex]a_{n}[/tex] = -385
[tex]a_{1}[/tex] = 7
d = difference between a term and its previous term = 3 - 7 = -4
Put these values in equation 1 , we will get
-385 = 7 + (n-1) (-4)
392 = 4n -4
4n = 396
n = 99
So we can conclude that the 99th term of the arithmetic sequence 7, 3, -1, -5, ... is -385.

Using the figure below, Maggie used the definition of vertical angles to help her solve for x. Since vertical angles are congruent, she set the two given expressions equal to each other. After solving for x, her teacher said she got the wrong value for x. Explain where Maggie made her mistake when solving for x.
Using vertical angles, Maggie made her mistake when combining the like terms of x, which has a result of -3x and not 3x, hence the correct result is of x = 9.
What are vertical angles?Vertical angles are two angles that are opposite by the same vertex when two lines cross each other, and they are congruent, that is, they have the same measure.
For this problem, the vertical angles are given as follows:
4x + 2.7x - 25.Since they are congruent, we can solve for the variable x as follows:
4x + 2 = 7x - 25.
Moving all the terms with x to the left side of the equality and all the constant terms to the right side, with opposite signal, we have that:
4x - 7x = -25 - 2
Combining the like terms, it is found that:
-3x = -27.
Here happened Maggie's mistake, as 4x - 7x = -3x, hence the correct solution is given by:
3x = 27
x = 27/3
x = 9.

a) The tree diagram is given by the image at the end of the answer.
b) The probability is of 0.18 = 18%.
c) The probability is of 0.72 = 72%.
What is a probability?A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.
For item a in this problem, we have two independent events, hence the tree diagram will contain two nodes, one with each event and it's probabilities.
For item b, since the events are independent, to find the probability of both, we multiply the probability of each, hence:
0.3 x 0.6 = 0.18.
For item c, first we find the probability of none being completed, hence:
(1 - 0.3) x (1 - 0.6) = 0.7 x 0.4 = 0.28.
At least one is complementary to none, hence the probability is given as follows:
p = 1 - 0.28 = 0.72 = 72%.

If the polygon is translated 4 units down and 5 units right, what will the coordinates of the new image be? Use prime notation in expressing the new coordinates. (5 points)HELP ASAP
The coordinates of the image of polygon A'B'C'D' would be A' (-1, 1), B' (-1, -2), C' (3, -2), D' (3, 2).
What is a translation?A translation can be defined as a type of transformation which moves every point of the object in the same direction, as well as for the same distance.
Since the pre-image of polygon ABCD is translated (shifted) vertically downward by 4 units and right 5 units, the coordinates of the image of polygon A'B'C'D' would be given by:
(x, y) → (x + 5, y - 4)

what is the percent of 10 of 20 please give me a better understanding
We need to calculate the 10% of 20. By definition, a% is:
[tex]a\text{ \%}=\frac{a}{100}[/tex]Where a can be any positive number. In this case a = 10, then:
[tex]10\text{ \%}=\frac{10}{100}=\frac{1}{10}[/tex]In mathematics, the word "of" is reserved for the product. Then 10% of 20 is just:
[tex]10\text{ \% of }20=\frac{1}{10}\cdot20[/tex]Solving this leads to 2.
Answer:
50 percent.
Step-by-step explanation:
10 of 20 as a fraction is
10/20
- divide top and bottom by 10 and this simplifies to
1/2.
To convert to a percentage we multiply by 100:
= 1/2 * 100
= 50%.

Answer: c
Step-by-step explanation:
The solution set for the inequality is p > -9.4. See attachment below for the graph.
How to Graph the Solution Set for an Inequality?An open circle is used when the inequality sign involved is ">" or "<". That is, it is used for numbers that are less than or greater than.
An arrow shaded to the right means the solution set is greater than a given value, while an arrow shaded to the left means the solution set includes all values that are less than a given value.
Given the inequality, p + 3.6 > −5.8, solve for p:
p + 3.6 > −5.8
Subtract 3.6 from both sides
p + 3.6 - 3.6 > -5.8 - 3.6
p > -9.4
Thus, the solution set would be all the values that are greater than -9.4. The graph is shown below.
