What is trend analysis?Trend analysis uses observed historical data to predict future developments and monitor performances about a particular topic.
Undertaking a trend analysis for sales, which is a technical analysis, involves setting a base year. The sales figure for the base year is set to 100% and used to check changes during the review periods.
The other years' sales results, in percentages, are compared to the base year by dividing each year's sales by the base year.
Sales Trend Analysis:2013 (D) = 32% ($158,000/$500,000 x 100)

Givena² + b² = 15,ab = 3.FindValue of (a - b)²SolutionUse identity:
(a - b)² = a² - 2ab + b²Substitute values:
(a - b)² = a² + b² - 2ab = 15 - 2*3 = 15 - 6 = 9Answer:
(a - b)² = 9
Step-by-step explanation:
Expand (a - b)²:
[tex]\begin{aligned}\implies (a-b)^2&=a^2-2ab+b^2\\&=a^2+b^2-2ab\end{aligned}[/tex]
Given:

If a standardized exam's scores are normally distributed. The z-scores that correspond to each value are 1.22, -0.75, 2.18,- 0.31.
How to find the z-score?mu = population mean = 1487
sigma = population standard deviation = 314
x =1870
z = (x - mu)/σ
z = (1870-1487)/314

Step-by-step explanation:
we need to remember the squared numbers of the baud integers :
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
9² = 81
10² = 100
so, what squared integers are closest to 83 and 35 ?
well, 81 (9²) and 36 (6²).
so, the result has to be closest to 9 - 6 = 3.
83 is larger than 81 than 35 is smaller than 36. so, 3 is less than sqrt(83) - sqrt(35).

What is an exponential function?The definition of an exponential function is presented as follows:
[tex]y = ab^x[/tex]
In which the variables of the function are listed as follows:
a is the numeric value of the function when the input is of x = 0.b is the rate of change of the function, which is the constant by which y is multiplied when x is increased by one.From this data-set, when x increases by one, y is multiplied by 2, hence the rate of change is:
b = 2.
When x is increased by n, the rate of change is:
b^n = 2^n.
Hence, when x is increased by 2, from 2 to 4, in item c, the rate of change is:
2² = 4.
When x = 1, the output is the output at x = 0 multiplied by 2, hence the coefficient a of the function is given as follows:
a = 2/2 = 1.
Then the exponential function is:

Answers
The vertical asymptote of a given function is x = -2 and x = -3.
What is the vertical asymptote of a function?
A vertical line that directs the function's graph but is not actually a part of it is called a vertical asymptote. It appears at the x-value that is outside the domain of the function, therefore the graph can never cross it.
To find the vertical asymptotes, set the denominator equal to zero and solve for x.
For the given function,
[tex]F(x) = \frac{1}{7(x+2)(x+3)}[/tex]
To find the vertical asymptote, equate the denominator to zero.
7(x + 2)(x + 3) = 0
(x + 2)(x + 3) = 0
x + 2 = 0 (or) x + 3 = 0
x = -2 (or) x = -3
Hence, The vertical asymptote of the given function is x = -2 and x = -3.

This is just an example on how to simplify fractions: Write the simplified form of the fraction 12/24.
The given fraction is 12/24.
Step 1: Let us write the factors of 12 and 24.
Factors of 12 are: 1, 2, 3, 4, 6, 12
Factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24
Step 2: Let us identify the common factors of 12 and 24.
Common factors are: 1, 2, 3, 4, 6, 12
Step 3: Keep dividing the numerator and denominator by the common factors.
(12 ÷ 2)/(24 ÷ 2) = 6/12
And
(6 ÷ 2)/(12 ÷ 2) = 3/6
Now divide by 3,
(3 ÷ 3)/(6 ÷ 3) = 1/2
Thus, 1/2 is the simplified fraction of 12/24.

What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The domain and the range is shown in table.
Two points on the line are (2, 5) and (7, 20).
Now,
Since, The equation of line passes through the points (2, 5) and (7, 20).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (20 - 5) / (7 - 2)
m = 15 / 5
m = 3
Thus, The equation of line with slope 3 is,
⇒ y - 5 = 3 (x - 2)
⇒ y - 5 = 3x - 6
⇒ y = 3x - 6 + 5
⇒ y = 3x - 1

The penguin's depth after 4 minutes is d = 10.7 + 146m
what is rate?A rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate. The word "per" can be further replaced by the symbol "/" in problems.
if the penguin moves with a speed of 146 meters per minute, then its distance after m minutes is = 146 x m
Since it moved from an elevation 10.7 below the sea surface, its total distance(d) would be = 10.7 + 146m
substitute m = 4 minutes,
we have
d = 10.7 + 146(4)

Answers
R₀, 270° is the rule that describes the transformation
How to determine the rule that describes the transformation?
Rotation simply means turning. In a cartesian plane, if a point P, whose position vector is (x,y), is rotated through θ° about the origin, the position of the image P' is
a. (-y, x) for θ = 90°
b. (-x, -y) for θ = 180°
c. (y, -x) for θ = 270°
Given the: Triangle RST with vertices R(2, 0), S(4, 0), and T(1, -3). And the image of triangle RST after a rotation has vertices R'(0, -2). S'(0, -4), and T(-3, -1)
From the given vertices it is obvious that the relation between preimage and image is defined as
(x, y) => (y, -x)
Therefore, the rule that describes the transformation is (y, -x) for θ = 270° (i.e. when the figure rotates 270° counterclockwise). So the third option (R₀, 270° ) is the answer.

Does 4f+2(12 f−4)=3(2f−4)−f+3 have one solution, no solution, or infinitely many solutions?
Answers
Based on the calculations, this equation 4f + 2(12f − 4) = 3(2f − 4) − f + 3 has one solution, which is equal to -1/23.
What is no solution?In Mathematics, no solution is also referred to as zero solution, and an equation is said to have no solution when the left hand side and right hand side of the equation are not the same or equal.
This ultimately implies that, an equation would have no solution or zero solution when both sides of the equal sign are not the same and the variables cancel out.
From the information provided, we have the following equation:
4f + 2(12f − 4) = 3(2f − 4) − f + 3
Opening the bracket, we have:
4f + 24f - 8 = 6f - 12 - f + 3
28f - 8 = 5f - 9
By collecting like terms, we have the following:
28f - 5f = -9 + 8
23f = -1
Dividing both sides by 23, we have:
f = -1/23

Answers
The total amount Jaxon should paid for the apples is 12 dollars which is 1200 cents.
Given,
The quantity of apple bought by Jaxon = 10 2/3 pounds
The cost of one pound of apple = $1.80
We have to find the total amount Jaxon should paid for the apples, in dollars and cents;
Here,
Total amount Jaxon should paid = Quantity of apple bought by Jaxon × Cost of one pound of apple
Total amount Jaxon should paid = 10 2/3 × 1.80
Total amount Jaxon should paid = 12 dollars
1 dollar is equal to 100 cents
