With your team, create a piecewise-defined function with at least three “pieces.” The function does not need to be a step-function with horizontal line segments, but it needs to meet the definition of a function. Make a table and a graph for your function, and write an equation for each part. Be sure to state the domain for each part, as well as the domain for the whole function.

eg n=1
n=2
n=3
5x1 - 9
5x2 -9
5x3 -9
Answer and Step-by-step explanation:
What this question wants you to do is fill out the right side (or the outputs) of the table.
To do this, plug in the value of n into the equation and solve.
n = n, 5n - 9
n = 1, 5(1) - 9 = -4
n = 2, 5(2) - 9 = 10 - 9 = 1
n = 3, 5(3) - 9 = 15 - 9 = 6
So, the values (in bold) should go into the table as so:

\(\sqrt{9x^2+36\) , x/2=cot(∅)
Answers
Answer:
\(\sqrt{9x^2+36} = 6 \csc(\theta)\)
Step-by-step explanation:
Given
\(\frac{x}{2}=\cot(\theta)\)
Required
Express \(\sqrt{9x^2+36}\) as trigonometry expression
\(\sqrt{9x^2+36}\)
Factorize
\(\sqrt{9x^2+36} = \sqrt{9(x^2+4)}\)
Split
\(\sqrt{9x^2+36} = \sqrt{9} * \sqrt{(x^2+4)}\)
\(\sqrt{9x^2+36} = 3 * \sqrt{(x^2+4)}\)
\(\sqrt{9x^2+36} = 3\sqrt{(x^2+4)}\)
We have:
\(\frac{x}{2}=\cot(\theta)\)
Make x the subject
\(x = 2 \cot(\theta)\)
So:
\(\sqrt{9x^2+36} = 3\sqrt{(x^2+4)}\)
\(\sqrt{9x^2+36} = 3\sqrt{((2 \cot(\theta))^2+4)}\)
Evaluate all squares
\(\sqrt{9x^2+36} = 3\sqrt{4\cot^2(\theta)+4}\)
Factorize
\(\sqrt{9x^2+36} = 3\sqrt{4(\cot^2(\theta)+1)}\)
Split
\(\sqrt{9x^2+36} = 3\sqrt{4} * \sqrt{\cot^2(\theta)+1}\)
\(\sqrt{9x^2+36} = 3*2 * \sqrt{\cot^2(\theta)+1}\)
\(\sqrt{9x^2+36} = 6 * \sqrt{\cot^2(\theta)+1}\)
In trigonometry
\(\cot^2(\theta)+1 = \csc^2(\theta)\)
So, we have:
\(\sqrt{9x^2+36} = 6 * \sqrt{\csc^2(\theta)}\)
Evaluate the square root
\(\sqrt{9x^2+36} = 6 * \csc(\theta)\)
\(\sqrt{9x^2+36} = 6 \csc(\theta)\)

The name given to a triangle containing the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

Abby is buying a car. If the

$500 down and monthly
payments of $100. Write an
equation for when y, the
money she has paid for the
car is a function of x, the
number of months she has
made payments on the car.
Answers
Down payment = down payment percent times purchase price.
How do you figure out your down payment?The down payment is computed as down payment Equals down payment % times purchase price. For this computation, the down payment percentage must be converted to a decimal. Divide your annual interest rate by the amount of payments you’ll make. If your interest rate is 6% and you make monthly payments, divide 0.06 by 12 to get 0.005. Multiply that figure by your remaining loan balance to get how much interest you’ll pay that month.
The Excel PMT function is a financial function that computes loan payments based on a fixed interest rate, the number of periods, and the loan amount. The acronym “PMT” refers for “payment” hence the function’s name.

Fred brought a shirt and a wallet for a total of 34.26 before tax. The price of the wallet was $15 less than the price of the shirt. What was the price of the shirt?
Answers
Answer:
The price of the shirt is $24.63.
Step-by-step explanation:
Let's assume the price of the shirt is x. Then the price of the wallet will be x - 15. We know that the total cost before tax is 34.26, so we can set up the equation:
x + (x - 15) = 34.26
Simplifying, we get:
2x - 15 = 34.26
Adding 15 on both sides:
2x = 49.26
Dividing by 2:
x = 24.63
Therefore, the price of the shirt is $24.63.

A bank wants to estimate the difference in the proportion of its "big" customers who have a second account with a different bank and the proportion of its "small" customers who also have an account with another bank. Of the 200 “big” customers who were randomly selected, 160 claimed to also bank with other banks. Of the 300 “small” customers who were randomly selected, 120 claimed to also bank with other banks.
Based on the 99% confidence interval (0.297, 0.503), is there convincing evidence of a difference in the proportion of “big” bank customers who bank with more than one bank as compared with the “small” customers who bank with more than one bank?
Because
contained in the interval, there is
to believe there
a difference in the proportion of “big” bank customers who bank with more than one bank as compared to the “small” customers who bank with more than one bank.
Answers
Yes, based on the 99% confidence interval (0.297, 0.503), there is convincing evidence of a difference in the proportion of "big" bank customers who bank with more than one bank compared to the "small" customers who bank with more than one bank.
The confidence interval (0.297, 0.503) represents the range of values within which the true difference in proportions between the two customer groups is likely to fall with 99% confidence. Since the interval does not include zero (0), we can conclude that there is a statistically significant difference between the proportions.
To further explain, the confidence interval was constructed using the sample proportions and the standard error. The sample proportion for the "big" customers who bank with other banks is 160/200 = 0.8, and for the "small" customers, it is 120/300 = 0.4. The standard error takes into account the sample sizes and proportions, and it measures the uncertainty in the estimation.
Since the confidence interval does not include zero, it indicates that the true difference in proportions is unlikely to be zero. In other words, there is strong evidence that the proportion of "big" bank customers who bank with more than one bank is higher than the proportion of "small" customers who do the same.
Therefore, based on the provided data and the confidence interval, we can conclude that there is convincing evidence of a difference in the proportion of "big" bank customers who bank with more than one bank compared to the "small" customers who bank with more than one bank.

for the given
Answers
When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.
The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.
Replacing x with 1, we have:
ƒ(1) = -4(1) - 5
Simplifying further:
ƒ(1) = -4 - 5
ƒ(1) = -9
Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.
Let's break down the steps taken to arrive at the solution:
1. Start with the function f(x) = -4x - 5.
2. Replace x with 1 in the function.
3. Evaluate the expression by performing the necessary operations.
4. Simplify the expression to obtain the final result.
In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.
It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.
Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.

Use the unit circle to find the value of sin (-90)
Answers
The value of Sin(90) is equal to 1.
What are trigonometric functions?In mathematics, trigonometric functions are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant, and Cotangent.
Given here: Sin(90) and to find the value using the unit circle
Rotate ‘r’ anticlockwise to form a 90° angle with the positive x-axis.
The sin of 90 degrees equals the y-coordinate(1) of the point of intersection (0, 1) of unit circle and r.
The value of sin 90 degrees can be calculated by constructing an angle of 90° with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of sin 90° is equal to the y-coordinate (1). ∴ sin 90° = 1.
Hence, Sin (90) is equal to 1.
