f(x) is the same thing as y so you can solve it the same way as any other equation. the only difference is when it has a number in the parentheses. if there is a number in the parentheses you will replace all of the x’s in the equation with that number. for example:

A set of numbers is given below.
{v/72 9.25, /83, pi 2 8.7}
Which list correctly orders the numbers from least to greatest
Answers
Answer:
Option (2)
Step-by-step explanation:
From the given set of numbers we have to arrange them in the increasing order.
{\(\sqrt{72},9.25,\sqrt{83},\pi^2,8.7\)}
Since, \(\sqrt{72}=8.49\)
\(\sqrt{83}=9.11\)
\(\pi ^2\) = 9.87
Therefore, set of numbers will be in the form of,
{8.49, 9.25, 9.11, 9.87, 8.7}
Now arranging these numbers in the increasing order,
8.49 < 8.7 < 9.11 < 9.25 < 9.87
Therefore, numbers in the increasing order will be,
{\(\sqrt{72},8.7,\sqrt{83},9.25,\pi ^{2}\)}

A taxi costs $2.50 and $0.20 for each 1/8 mile driven. Find the cost for hiring a taxi to get from the airport to your hotel if the distance is 9 1/2 miles.
Answers
The cost of hiring a taxi to travel 9 1/2 miles from the airport to the hotel is $19.50.
To calculate the cost, we need to consider both the fixed cost and the variable cost based on the distance traveled.
The fixed cost for hiring a taxi is $2.50.
The variable cost is based on the distance traveled, with a rate of $0.20 for each 1/8 mile driven. To convert the distance of 9 1/2 miles to the fraction of 1/8 mile, we can multiply it by 8, resulting in 76/8 miles.
Now, we can calculate the variable cost by multiplying the distance in 1/8 mile increments (76/8) by the rate of $0.20:
Variable cost = (76/8) * $0.20 = $9.50.
Finally, to find the total cost, we add the fixed cost and the variable cost:
Total cost = Fixed cost + Variable cost = $2.50 + $9.50 = $12.
Therefore, the cost of hiring a taxi to travel 9 1/2 miles from the airport to the hotel is $19.50.

3. If $1100 is invested at an interest rate, r, compounded annually, the amount in the account after 4 years is given by the polynomial function A (r) = 1100 (1 + r)4. Graph this function in an appropriate window. Describe how this function is transformed from the graph of f(r) = rª. At what interest rate would the money need to be invested in order to yield $2281 after 4 years? Show how this answer is represented on the graph of y = A(r). Verify this result by solving for this value algebraically.
Answers
An interest rate of approximately 8.09% compounded annually would yield $2281 after 4 years with an initial investment of $1100.
How to explain the functionThe function A(r) = 1100(1+r)^4 represents the amount in the account after 4 years with an initial investment of $1100 and an annual interest rate of r compounded annually.
It should be noted that to describe how this function is transformed from the graph of f(r) = r^a, we can compare the exponents in the two functions. The exponent in A(r) is 4, while the exponent in f(r) is a. The effect of changing the exponent from a to 4 is to increase the growth rate of the function. As the exponent increases, the function grows more quickly. In this case, raising the interest rate to the fourth power leads to a more significant growth in the account balance over time.
In this case, to find the interest rate that would yield $2281 after 4 years, we can set A(r) equal to 2281 and solve for r:
2281 = 1100(1+r)⁴
(1+r)^4 = 2281/1100
1+r = (2281/1100)^(1/4)
r = (2281/1100)^(1/4) - 1
r ≈ 0.0809
Therefore, an interest rate of approximately 8.09% compounded annually would yield $2281 after 4 years with an initial investment of $1100.

The height of the probability density function f(x) of the uniform distribution defined on the interval [a, b] is 1/(a-b). True False
Answers
The statement "The height of the probability density function f(x) of the uniform distribution defined on the interval [a, b] is 1/(a-b)" is False.
In a uniform distribution, the probability density function (PDF) is constant within the interval [a, b]. The height of the PDF represents the density of the probability distribution at any given point within the interval. Since the PDF is constant, the height remains the same throughout the interval.
To determine the height of the PDF, we need to consider the interval length. In a uniform distribution defined on the interval [a, b], the height of the PDF is 1/(b - a) for the PDF to integrate to 1 over the entire interval. This means that the total area under the PDF curve is equal to 1, representing the total probability within the interval [a, b].
Therefore, the correct statement is that the height of the probability density function f(x) of the uniform distribution defined on the interval [a, b] is not 1/(a - b), but rather it is a constant value necessary for the PDF to integrate to 1 over the interval, i.e., 1/(b - a).

A number is 2 times another number. If the larger number is increased by 14, the result is 4 less than 4 times the smaller number.
Answers
The smaller number is 9 and the larger number is 18.
According to the question,
We have the following information:
A number is 2 times another number. If the larger number is increased by 14, the result is 4 less than 4 times the smaller number.
Now, let's take the larger number to be x and the smaller number to be y.
So, we have the following expressions:
x = 2y ...(1)
x+14 = 4y-4
Putting the values of x from the equation 1:
2y+14 = 4y-4
Adding 4 to both sides of the equation:
2y+14+4 = 4y
2y+18 = 4y
Subtracting 2y from both sides of the equation:
18 = 4y-2y
18 = 2y
Dividing by 2 on both sides:
y = 18/2
y = 9
Now, putting this value in equation 1:
x = 2y
x = 2*9
x = 18
Hence, the smaller number is 9 and the larger number is 18.

Which of the following is not an item in the income statement? SELECT ONLY ONE a. Discount allowed b. Furniture & Fixture c. Furniture & Fixture d. Discount received
Answers
The item that is not an item in the income statement is b. Furniture & Fixture as it is considered a fixed asset and is reported on the balance sheet instead.
The income statement, also known as the profit and loss statement, provides a summary of a company's revenues, expenses, gains, and losses over a specific period. It helps to assess the financial performance of a business. The income statement typically includes various items such as revenues, cost of goods sold, operating expenses, interest income or expense, and other gains or losses.
a. Discount allowed is a revenue item that represents the discounts given to customers as an incentive for early payment or other reasons. It is usually reported as a deduction from sales revenue.
c. Furniture & Fixture is not typically included in the income statement. Instead, it is considered a non-operating or non-recurring item and is generally classified as a fixed asset on the balance sheet. Fixed assets represent long-term investments made by a company for its operations.
d. Discount received is also not an item in the income statement. It represents the discounts received by a company from its suppliers for early payment or other reasons. Similar to discount allowed, it is usually reported as a deduction from the respective expense account.
In summary, b. Furniture & Fixture is the item that is not included in the income statement. It is considered a fixed asset and is reported on the balance sheet instead.

What is the formula for the indicated variables? A-lw wh + lh, for w
Answers
Hello there. To solve this question, we have to remember some properties about solving equations for a variable.
Given the following equation:
\(A=lw+wh+lh\)We want to solve it for w.
First, notice we can group some factors
\(A=w\cdot(l+h)+lh\)Subtract lh on both sides of the equation
\(A-lh=w\cdot(l+h)\)Assuming l + h is not equal to zero, divide both sides of the equation by this factor
\(w=\dfrac{A-lh}{l+h}\)This is the answer to this question.
