Suppose you are a new employee. You notice that each payment option describes a sequence and decide to use rules to help determine which option to take.
Determine the iterative rule for each sequence. Show your work.
Your friend trusts your tables in Problem 1, but wonders if you wrote the iterative rules correctly. Show two calculations to convince your friend that both your rules work.
my table is below (it is correct, I checked with my math teacher, it is ten percent added to the previous week for all you doubters)
The iterative rule for each sequence in the table will be to use the slope-intercept form of the equation of a line y=mx+b.
How to depict the information?In this situation, x is the week, and y is the amount paid. Basically, you need to find the slope, represented by m, which is the amount the amount paid increases by each week, and the y-intercept, b, which is the "amount paid" at week 0.
The x-coordinate is the week, and the y coordinate is the amount paid. Because the weeks are incrementing by 1, x2-x1=1.
After that, to complete the rule, you need to find the y-intercept. If the amount paid is 200 on week 1, and the amount paid increases by 50 each week.
Another way to think about it is by plugging your points into the incomplete rule. Let b represent the y-intercept. Plug in the values for week 1 and solve for b.
The calculations to convince your friend that both your rules work are:
m=(y2-y1)/(x2-x1)
(x1,y1)=(1,200)
(x2,y2)=(2,250)
m=(250-200)/(2-1)
=50/1 =50

Find the equation for the line that passes through the point (2, -3), and that is parallel to the line with the equation x - 3y = 3
Step-by-step explanation:
the slope of a line is the factor of x, when the equating looks like
y = ...
so,
x - 3y = 3
x = 3y + 3
3y = x - 3
y = 1/3 x - 1
so, the original slope is 1/3.
a parallel line has the same slope.
having a specific point we can use the point-slope form as equation :
y - y1 = m(x - x1)
with m being the slope, and (x1, y1) being a point on the line.
y - -3 = 1/3(x - 2)
y + 3 = 1/3(x - 2)
simplified that is
y + 3 = 1/3 x - 2/3
y = 1/3 x - 2/3 - 3 = 1/3 x - 2/3 - 9/3 = 1/3 x - 11/3 =
= 1/3 × (x - 11)
Answer:
[tex]y=\frac{1}{3}x - \frac{11}{3}[/tex]
Step-by-step explanation:
We are given the line x-3y=3.
We want to write the equation of the line that is parallel to this line, and that passes through (2, -3).
Parallel lines have the same slope.
Therefore, let's find the slope of x-3y=3.
The line is currently written in standard form, which is ax+by=c, where a, b, and c are free integer coefficients.
In order to find the slope of this line, we can convert it into slope-intercept form, which is y=mx+b, where m is the slope and b is the value of y at the y intercept.
To do that, we need to isolate y on one side; this is the same as solving the equation for y.
x - 3y = 3
Start by subtracting x from both sides
-3y = -x + 3
Now divide both sides by -3
[tex]y = \frac{1}{3} x - 1[/tex]
The slope of the line is 1/3, as 1/3 is the coefficient in front of x.
It is also the slope of our new line.
Since the question doesn't specify which format for the equation of the line, we can use any form. However, let's put the equation of the new line into slope-intercept form.
So, substitute 1/3 as m in y=mx+b.
[tex]y = \frac{1}{3} x + b[/tex]
Now we need to find b.
As the equation passes through the point (2, -3), we can use its values to help solve for b.
Substitute 2 as x and -3 as y.
[tex]-3 = \frac{1}{3} (2) + b[/tex]
Multiply.
[tex]-3 = \frac{2}{3} + b[/tex]
Subtract 2/3 from both sides (we can write this as an improper fraction).
[tex]-\frac{11}{3} = b[/tex]
Substitute -11/3 as b in the equation.
[tex]y=\frac{1}{3}x - \frac{11}{3}[/tex]

The trigonometric identity (cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = cos⁴θ
How to solve the trigonometric identity?
Since (cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = [(cos²θ)² - (sin²θ)²]/[1 - (tan²θ)²]
Using the identity a² - b² = (a + b)(a - b), we have
(cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = [(cos²θ)² - (sin²θ)²]/[1 - (tan²θ)²]
= (cos²θ - sin²θ)(cos²θ + sin²θ)/[(1 - tan²θ)(1 + tan²θ)] =
= (cos²θ - sin²θ) × 1/[(1 - tan²θ)sec²θ] (since (cos²θ + sin²θ) = 1 and 1 + tan²θ = sec²θ)
Also, Using the identity a² - b² = (a + b)(a - b), we have
(cos²θ - sin²θ) × 1/[(1 - tan²θ)sec²θ] = (cosθ - sinθ)(cosθ + sinθ)/[(1 - tanθ)(1 + tanθ)sec²θ]
= (cosθ - sinθ)(cosθ + sinθ)/[(cosθ - sinθ)/cosθ × (cosθ + sinθ)/cosθ × sec²θ]
= (cosθ - sinθ)(cosθ + sinθ)/[(cosθ - sinθ)(cosθ + sinθ)/cos²θ × 1/cos²θ]
= (cosθ - sinθ)(cosθ + sinθ)cos⁴θ/[(cosθ - sinθ)(cosθ + sinθ)]
= 1 × cos⁴θ
= cos⁴θ
So, the trigonometric identity (cos⁴θ - sin⁴θ)/(1 - tan⁴θ) = cos⁴θ

Matthew picks flowers and sells them to tourists. the function s(t) approximates how many flowers matthew picks per hour. the function w(h) represents how hours per week matthew spends picking flowers. what are the units of measurement for the composite function s(w(h))?
Flowers/week is the unit of measurement for the composite function s(W(h)).
Given that the function w(h) indicates the number of hours per week that Matthew spends picking flowers and the function s(t) approximates how many flowers he collects every hour.
The process of combining two or more functions into one function is known as the composition of functions. The output of the function enclosed in parenthesis becomes the input of the function outside of them in a composition of functions.
Hours of flowers is the unit of function s(t).
Additionally, consider that W(h) denotes the number of hours per week that Matthew spends gathering flowers.
W(h) = hours/week as a unit.
The unit of the composite function s(W(h)) will be = (Flowershours)(hoursweek) = Flowersweek.
Hence, the units of measurement for the composite function s(W(h))where the function s(t) approximates how many flowers Matthew picks per hour and the function w(h) represents how hours per week Matthew spends picking flowers is flowers/week.
