The observation I can make of the pattern is that the sequence always increase by 10.
How to solve an arithmetic pattern?The sequence above shows an arithmetic pattern. Therefore, the arithmetic formula can be used to solve the next sequence.
7, 17, 27, 37, 47, 57..
Therefore,
aₙ = a + (n - 1)d
where
a = first termd = common differencen = number of termsTherefore,
a = 7
d = 17 - 7 = 10
Hence, the arithmetic formula is as follows:
aₙ = 7 + (n - 1)10
aₙ = 7 + 10n - 10
aₙ = 10n - 3
The sequence always increase by 10.

Answer:
[tex]f(x)=6(x-2)^2+18[/tex]
Step-by-step explanation:
Given quadratic function:
[tex]f(x)=6x^2-24x+42[/tex]
To complete the square, begin by grouping the x terms within parentheses:
[tex]\implies f(x)=(6x^2-24x)+42[/tex]
Factor out the coefficient of x²:
[tex]f(x)=6\left(x^2-4x\right)+42[/tex]
Add the square of half the coefficient of the term in x inside the parentheses, and subtract the distributed value outside the parentheses:
[tex]\implies f(x)=6\left(x^2-4x+\left(\dfrac{-4}{2}\right)^2\right)+42-6\left(\dfrac{-4}{2}\right)^2[/tex]
Simplify:
[tex]\implies f(x)=6\left(x^2-4x+\left(-2\right)^2\right)+42-6\left(-2\right)^2[/tex]
[tex]\implies f(x)=6\left(x^2-4x+4\right)+42-6\left(4)[/tex]
[tex]\implies f(x)=6\left(x^2-4x+4\right)+42-24[/tex]
[tex]\implies f(x)=6\left(x^2-4x+4\right)+18[/tex]
Factor the perfect square trinomial inside the parentheses:
[tex]\implies f(x)=6(x-2)^2+18[/tex]
[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Vertex form of a quadratic equation}\\\\$y=a(x-h)^2+k$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the vertex. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]
Comparing the derived equation with the vertex formula, the vertex of the derived equation is (2, 18). Hence the completion of the square is correct.

At a sale this week, a desk is being sold for $108.80 This is a 66% discount from the original price.
What is the original price?
Answer:
[tex]\$320.29[/tex]
Step-by-step explanation:
Determine the formula:
[tex]x - (x \times 0.66) = 108.90[/tex]
Solve for x to get the original price:
[tex]x - (x \times 0.66) = 108.90\\x - 0.66x = 108.90\\x(1-0.66) = 108.90\\x = \frac{108.90}{1-0.66}\\x = \frac{108.90}{0.34}\\x \approx 320.29[/tex]

Step-by-step explanation:
Consider the following y-intercept and slope:
(0,−3), m=12
Step 2 of 2 : Determine the graph of the line with the given y-intercept and slope.
The equation of the line will be y = 12x -3 and the graph of the line with the given y-intercept and slope is shown below.
First, let us understand the slope intercept form of a line:
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept.
We are given:
(0, −3), m = 12.
We need to determine the graph of the line with the given y-intercept and slope.
To find the value of b;
substitute the given values in the equation of the line, we will get;
y = mx + b
-3 = 12 *0 + b
b = -3
So, the equation of the line will be:
y = 12x -3
Thus, the equation of the line will be y = 12x -3 and the graph of the line with the given y-intercept and slope is shown below.

What is y-intercept?In Mathematics, the y-intercept of any graph such as a linear function, generally occur at the point where the value of "x" is equal to zero (x = 0).
How to calculate the slope and equation of this line?Mathematically, the slope-intercept form of a line can be calculated by using this equation:
y = mx + c
Where:
m represents the slope of a line.x and y are the points on a graph.c represents the y-intercept.Making slope (m) the subject of formula, we have the following:
Slope, m = (y - c)/x
Slope, m = (1 - (-2.5))/-2
Slope, m = (1 + 2.5)/-2
Slope, m = -3.5/2
Slope, m = -1.75.

3. Your original purchase price was $825.00 plus 7% sales tax. You enter into an agreement
where the interest (12.5% APR) is waived for the first 12 months provided you make the
required monthly payments; otherwise the interest is accrued from the date of purchase. You
miss the first payment due date. The late fee is $35.00. How much is the interest?
O$103.13
O $110.34
O $8.59
O $9.20
The original price of purchasing is $825 plus 7% sales tax, then the interest will be $9.20. Hence, option D is correct.
What is the Percentage?The Latin term "per centum," which signifies "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship here between a component and a whole, in which the value of the whole is always assumed to be 100.
As per the given data in the question,
The original purchase price = $825
The sales tax = 7% of $825 = 825 × 7/100 = $57.75
Total credit = $825 + $57.75 = $882.75
The monthly interest rate = 12.5%/12 = 1.0417%
Interest = $882.75 × 1.0417/100
Interest = $9.20

According to the question,
The distribution of the number of daily request is bell-shapes means Number of daily request follows Normal distribution
Mean of normal distribution : μ = 36

The equation of the line that has a slope of -2 and x-intercept of -1 in point slope form is y = -2(x + 1).
How to write equation in point slope form?Linear equations can be represented in different form such as point slope form, slope intercept form, general form and standard form.
Therefore, let's represent the equation of the line in point slope form.
Using point slope form,
y - y₁ = m(x - x₁)
where
m = slopex₁ and y₁ are the variables.Therefore, the equation of the line has a slope of -2 and an x-intercept of -1.
The slope of a line is the change in the dependent variable with respect to the change in the independent variable.
The x-intercept is where a line crosses the x-axis. The x-intercept is the value of x when y = 0.
hence,
m = -2 and (-1, 0)
x₁ = -1
y₁ = 0

C. The y-intercept of the function f(w) represents the initial length of the petal.
D. The reasonable domain to plot the growth function is week 0 to week 2.
The length of the flower petal and the weeks passed are denoted by f(w) and w. The equation of the function is given below.
f(w) = 3(1.03)w
The simplified function is f(w) = 3.09w.
The rate of change of the function from weeks 2 to 5 is calculated below.
