The required paragraphs regarding with given expression f(x) = x²-2x+1/4x+5 have been explained later in the section.
A rational expression is a fraction in which the numerator and denominator are polynomials.
Here,
a) To determine the values of x that make the rational function f(x) equal to 0, we need to solve the equation:
x² - 2x + 1 = 0
Next, we can factor the quadratic on the left-hand side of the equation:
(x - 1)(x - 1) = 0
The quadratic is a perfect square, and we can see that it is equal to 0 when x = 1. So, the value of x that makes the rational function 0 is x = 1.
b) To determine the values of x where the rational function f(x) is undefined, we need to look for values of x that would make the denominator, 4x+5, equal to 0. If the denominator is equal to 0, then we would be dividing by 0, which is undefined.
So, we set the denominator equal to 0,
4x + 5 = 0
4x = -5
x = -5/4
Therefore, the value of x where the rational function is undefined is x = -5/4.

A graphing calculator is recommended. In this problem you are asked to find a function that models a real-life situation and then use the model to answer questions about the situation. Use the guidelines on page 237 to help you. A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 12 in, by 20 in. by cutting out equal squares of side x at eech corner and then folding up the sides (see the figure). 20 in. 12 in. (a) Find a function that models the volume V of the box. (b) Find the values of x for which the volume is greater than 230 in2. (Rgund your answers to three decimal places. Enter your answer using interval notation) (c) Find the largest volume that such a box can have. (Round your answer to three decimal places) in2
A function modeling the volume of the box can be found, and the values of x for which the volume is greater than 230 in2 are x = [-2.636, 2.636]. The largest volume is 480 in2, which is achieved when x = 5.
A function that models the volume V of the box can be found by subtracting four [tex]x2[/tex]from both the length and the width, and then multiplying the result to get the volume:
V = [tex](12 - 4x2)(20 - 4x2)[/tex]
To find the values of x for which the volume is greater than 230 in2, we can solve the equation
V = [tex](12 - 4x2)(20 - 4x2) = 230[/tex] for x.
This gives x values of ±2.636
Thus, the values of x for which the volume is greater than 230 in2 are x = [[tex]-2.636, 2.636[/tex]].
The largest volume that such a box can have is 480 in2, which is obtained when x is equal to the length or width divided by two. This occurs when x = 10/2 = 5. Thus, the largest volume that such a box can have is 480 in2.

Tamaya borrowed $8,500 to buy a car. After 42 months, she ended up paying $1,785 in interest on the car loan. What was the simple interest rate on Tamaya’s car loan?
Answer:
5%
Step-by-step explanation:
We can use the formula for simple interest to solve for the interest rate:
I = Prt
where:
I is the interest
P is the principal (the amount borrowed)
r is the interest rate
t is the time in years
We know the principal (P) is $8,500, the interest (I) is $1,785, and the time (t) is 42 months, or 42/12 = 3.5 years. So, we can plug in the values and solve for r:
I = Prt
$1,785 = $8,500 * r * 3.5
$1,785 / $8,500 / 3.5 = r
r = 0.05, or 5%
So, the simple interest rate on Tamaya's car loan was 5%.

4.)M=9,100(0.95)^6
Answer:
1.) M=9,100(1 + 0.05)^6
Step-by-step explanation:
Compound Interest Rate Formula:
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
In this formula the "P" represents the principle amount, or the original amount. The "r" represents the interest rate in decimal form, while the "n" represents the number of compounds in the time unit (usually years), and the "t" represents the amount of time that has passed (usually years)
In this case it says annual interest rate of 5% and nothing of compound monthly, etc... so n=1, and r=0.05. We're also given the principle amount of 9,100 and the time passed is just 6 years, so t=6. Plugging all this information into the equation we get:

factorise 1331x³y-11y³x pls i really need it!! thank you :) !!
Answer:
11xy(121x²-y²)
Step-by-step explanation:
When factorizing, you should always look for what each term has in common.
First, let's look at the coefficients (numbers) in each term: 1331 and 11. Both are divisible by 11, so let's factorize out 11:
1331x³y-11y³x
11(121x³y-y³x)
Looking at the terms in the bracket, we see they both have 'x's in common (121x³y has three x's multiplied in and y³x has one). Let's factorize out this x:
11(121x³y-y³x)
11x(121x²y-y³)
We can also see both terms in the brackets have 'y's in common (121x²y has one y and y³ has three multiplied in). Let's factorize out this y:
11x(121x²y-y³)
11xy(121x²-y²)
Since there is nothing in common left between the terms, we can say the expression is fully factorized!

of the time. Haris Rauf is bowling the last ball of the innings to Harry Brook. Before running in to
bowl this last ball, Haris Rauf has decided to bowl a yorker, what is the probability that a boundary
will be scored of this last ball of the innings.
Answer:
To solve it, you need to use probability. Let me show you how.
We can use a tree diagram to represent the possible outcomes of the last ball. Here is the diagram:
```
Haris Rauf
/ \
yorker full toss
0.8 0.2
/ \ / \
boundary no boundary boundary no boundary
0.2 0.8 0.9 0.1
```
The probability of a boundary is the sum of the probabilities of the branches that end with a boundary. To find the probability of each branch, we multiply the probabilities along the branch. For example, the probability of a yorker and a boundary is 0.8 × 0.2 = 0.16.
So, the probability of a boundary is:
0.8 × 0.2 + 0.2 × 0.9 = 0.16 + 0.18 = 0.34
Therefore, the probability that a boundary will be scored of the last ball is 0.34 or 34%.

Each worker at a store gets paid $15.90 for that first 40 hours worked. After 40 hours, they earn time and a half wages. Every employee has a 28% of his/her gross pay deducted for taxes, insurance etc. how much of a net pay does each worker take home?
Each worker would take home a net pay of $586.71.
What is the net pay?
The net pay is the amount of money that an employee takes home after all deductions have been made from their gross pay. Gross pay is the total amount of money an employee earns before taxes and other deductions are taken out.
To calculate net pay, you need to subtract all the required deductions from the employee's gross pay.
To calculate the net pay for each worker, we first need to determine their gross pay. The gross pay will depend on the number of hours they worked and whether they worked any overtime.
For the first 40 hours worked, each worker earns $15.90 per hour, so their gross pay for those hours would be:
Gross Pay for 40 hours = $15.90/hour x 40 hours = $636
For any hours worked beyond 40, the worker earns time and a half wages. This means they earn 1.5 times their regular hourly wage of $15.90, or $23.85 per hour. So, if they worked, for example, 45 hours in total, the additional 5 hours would be paid at the overtime rate, resulting in an additional gross pay of:
Gross Pay for 5 overtime hours = $23.85/hour x 1.5 x 5 hours = $178.88
Therefore, their total gross pay would be:
Total Gross Pay = Gross Pay for 40 hours + Gross Pay for 5 overtime hours = $636 + $178.88 = $814.88
Now, we need to calculate the deductions, which we are told are 28% of the gross pay. So the total deductions would be:
Total Deductions = 28% x $814.88 = $228.17
Finally, to determine the net pay, we need to subtract the total deductions from the gross pay:
Net Pay = Gross Pay - Total Deductions = $814.88 - $228.17 = $586.71
Therefore, each worker would take home a net pay of $586.71.

The median monthly rent in 1990 was $447 and $658 in 2002. What was the percent increase in the median monthly rent prices from 1990 to 2002? Round to the nearest tenth of a percent.
Answer:
Step-by-step explanation:
Step 1: Define each variable
Let's define some variables to make the calculations easier:
t1 = the median monthly rent in 1990, which is $447
t2 = the median monthly rent in 2002, which is $658
Δ = the change in median monthly rent, which is t2 - t1
Step 2: Calculate the change in median monthly rent
Δ = t2 - t1 = $658 - $447 = $211
This means that the median monthly rent increased by $211 from 1990 to 2002.
Step 3: Divide the change by the original amount
To find the percentage increase, we need to divide the change by the original amount and multiply by 100:
Δ / t1 * 100 = ($211 / $447) * 100 = 47.2%
This means that the median monthly rent increased by 47.2% from 1990 to 2002.
Step 4: Round to the nearest tenth of a percent
The final answer is 47.2%, rounded to the nearest tenth of a percent.
The percent increase in the median monthly rent prices from 1990 to 2002 was 47.2%.

One reason to compute a correlation coefficient to measure the strength of the relationship between two variables is that ______.
One reason to compute a correlation coefficient to measure the strength of the relationship between two variables is that quantify the strength and direction of the correlation in a precise and standardized way..
When we have two variables that are related, we say that there is a correlation between them. The most common way to visually represent a correlation is by plotting the data on a scatter plot, where each point represents a pair of values for the two variables.
While a scatter plot is a useful tool to visualize the relationship between two variables, it doesn't tell us how strong or weak the correlation is. For instance, two variables might show a positive correlation, but the scatter plot might be quite dispersed, indicating that there is a lot of variability in the data. In this case, we would say that the correlation is weak. On the other hand, if the scatter plot is tightly clustered around the line, we would say that the correlation is strong.
This is where the correlation coefficient comes in. The correlation coefficient is a mathematical measure that quantifies the strength and direction of the relationship between two variables. It ranges from -1 to 1, where a value of -1 indicates a perfect negative correlation, a value of 0 indicates no correlation, and a value of 1 indicates a perfect positive correlation.
To compute the correlation coefficient, we first need to calculate the covariance between the two variables. Covariance is a measure of how much the two variables vary together, and it is defined as the sum of the products of the deviations of the values from their respective means. Once we have the covariance, we can divide it by the product of the standard deviations of the two variables to get the correlation coefficient.

Which of the following equations represents a linear function? Please show the steps of the answer! Thank you
Answer:
2nd choice y = 1/2x - 5
Step-by-step explanation:
y = 1/2x - 5 is the only function listed that if you graph it, it makes a straight line. A linear function forms a straight line when it is plotted on a graph.
The first and last choices are number values of x.
The 3rd choice, if you graph it, makes a parabola.
Answer:
Second option:
[tex]y = \dfrac{1}{2}x -5[/tex]
Step-by-step explanation:
A linear function should have y as a function of x (or x as a function of y) and the degree of the function (the highest power has to be 1)
Both x and y must be present to make it a linear function
General slope intercept form is y = mx + b where m = slope, b = y-intercept
With these restrictions the second option is the correct one
[tex]y = \dfrac{1}{2}x -5[/tex]
This line is in slope intercept form y = mx + b where m = slope(in this case 1/2) and y-intercept b(in this cae -5)
Option 1: x = 3 is a straight vertical line parallel to the y-axis. Such a line has a slope of ∞
Option 3 is a function with degree 2 and is a quadratic function
Option 4 : 3x - 6 = 4==> 3x = 6 + 4 = 10 or x = 10/3, again another vertical line with slope = ∞

For number 6, it is not shown on the photo, sorry!
Step-by-step explanation:
2. The square at the corner means that it is 90°, so 90 - 34 = 56
4. The line is straight, so it means that it is 180°, so 180 - 124 = 56
A faucet gives 20 gallons of water in 5 seconds. How many gallons does it give in 7 seconds?
Answer:
28
Step-by-step explanation:
IF 20 GALLONS IS EQUIVALENT TO 5 SECONDS WHAT ABOUT 7 SECONDS
CROSS MULTIPLY
Answer:
20 gallons / 5 seconds = 4 gallons / second
Therefore, In 7 seconds you get (7 x 4 ) or 28 gallons.

a) The probability of rolling a 5 or a number greater than 3 is 1/2.
b) The probability of rolling a number less than 4 or an even number is 5/6.
c) The probability of rolling a 4 or an odd number is 2/3.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
In rolling a six-sided die, the total number of outcomes is 6.
The sample space is {1,2,3,4,5,6}
The probability formula is -
Probability = Number of outcomes corresponding to events / total number of outcomes.
(a) Let A be the event of rolling a 5. Then A = {5}.
Let B be the event of rolling a number greater than 3. Then B = {4,5,6}.
The event of rolling A or B is given by A∪B = {4,5,6}.
So, apply the probability formula -
P(A∪B) = 3/6 = 1/2
Therefore, the probability value is 1/2.
(b) Let C be the event of rolling a number less than 4. Then C = {1,2,3}.
Let D be the event of rolling an even number. Then D = {2,4,6}.
The event of rolling C or D is given by C∪D = {1,2,3,4,6}.
So, apply the probability formula -
P(C∪D) = 5/6
Therefore, the probability value is 5/6.
(c) Let E be the event of rolling a 4. Then E = {4}.
Let F be the event of rolling an odd number. Then F = {1,3,5}.
The event of rolling E or F is given by E∪F = {1,3,4,5}.
So, apply the probability formula -
P(E∪F) = 4/6 = 2/3
Therefore, the probability value is 2/3.
