At which root does the graph of f x x 5 3 * x 2 2 touch the X axis?
The root of the graph of f(x) =(x - 5)3(x + 2)2 touches the x-axis at -2,5
(x - 5)^3 has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.
(x + 2)^2 has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.
Given: Function f(x) is (x - 5)3(x + 2)2
If a curve touches the x-axis then f(x) = 0
⇒ (x - 5)3(x + 2)2 = 0.
But if ab = 0 ⇒ either a = 0 or b = 0 or both zero.
⇒ (x - 5)3 = 0 and (x + 2)2 = 0
⇒ (x - 5) = 0 and x + 2 = 0
⇒ x = 5 and x = - 2.

Determine whether each graph represents a function explain
The correct statement regarding whether each graph represents a function is given as follows:
a. Represents a function, as each input is mapped to only one output.
b. Does not represent a function, as there are inputs mapped to two outputs.
When does a graph represents a function?A graph will represent a function if the graph contains no vertically aligned points, that is, each value of x is mapped to only one value of y.
Vertically aligned points mean that a value of the input x is mapped to multiple values of the output y, that is, a single input is mapped to multiple outputs which disqualify the relation as a function.
In the context of this problem, we have that:
In the discrete graph a, each value of x, x = 1, x = 2, x = 3, x = 4 and x = 5, is mapped to only one value of y, hence the graph is a function.In the continuous graph b, there are values of x mapped to two values of y, hence it is not a function.On the continuous graph, a vertical line is drawn and shown at the end of the answer, representing visually when does a graph does not represent a function, as the vertical line crosses the function at multiple points.

umber cube has sides numbered 1 through 6. what is the probability that the outcome of the roll is a sum that is a multiple of 6 or a sum that is a multiple of 4?
The probability to obtain the sum of two rolled dice as a multiple of 6 or a multiple of 4 is 13/36.
What is defined as probability of an event?When comparing the likelihood of an outcome to all other possible outcomes, we use a sort of ratio known as probability.
Given that a dice is rolled twice. Sum of the two rolls has following possibilities,
2,3,4,5,6,7,8,9,10,11,12
A multiple of 6 is obtained when the sum is either 6 or 12.
Sum of 6 is obtained when the two rolls are (1,5) , (2,4) , (3,3), (4,2) , (5,1)
Probability for each is 1/36. Therefore total probability to obtain sum of 6 is 5/36.
Sum of 12 is obtained only when the two rolls (6,6).
Probability to obtain sum of 12 is therefore 1/36.
Similarly for a sum of 4, the probability is 3/36.
For a sum of 8, the probability is 4/36.
Therefore the required probability is the sum of above calculated probabilities,
Required probability = 5/36 + 1/36 + 3/36 + 4/36 = 13/36

how to determine if a function has a horizontal asymptote
If the function approaches a specific value (y = c) as x approaches infinity or negative infinity, then it has a horizontal asymptote at y = c.
To determine if a function has a horizontal asymptote, consider the behavior of the function as x approaches positive or negative infinity. The main idea is to analyze the end behavior of the function.
Degree of Polynomials:
If the degree of the numerator is less than the degree of the denominator, the function has a horizontal asymptote at y = 0 (the x-axis). If the degree of the numerator is equal to the degree of the denominator, divide the coefficients of the highest degree terms. The resulting ratio determines the horizontal asymptote. If the degrees are unequal, there is no horizontal asymptote.
Limits:
Take the limit of the function as x approaches positive or negative infinity. If the limit evaluates to a finite value, that value represents the horizontal asymptote. If the limit is infinite (∞) or does not exist, there is no horizontal asymptote.
Infinity:
If the function involves terms like exponential functions or logarithmic functions, analyze their behavior as x approaches infinity. Exponential functions with positive exponents tend to infinity, while those with negative exponents approach zero. Logarithmic functions tend to negative infinity as x approaches zero.
By considering these methods, you can determine if a function has a horizontal asymptote and find its equation or behavior as x approaches infinity or negative infinity. Remember to apply these techniques with caution and consider the specific characteristics of the function being analyzed.

8 men working assemble 466 application in a 12-hour shift.
a. find the constant proportionality then write the formula
b. If 3 report sick how long the others will work to accomplish the same task?
c. What if the management reports that due to a demand the task has to be accomplished in 4 hours, how many will be hired temporarily?
Answer:
Step-by-step :
a) To find the constant proportionality, we can use the formula:
Number of applications = k * (number of workers) * (number of hours)
where k is the constant proportionality we want to find. We can plug in the values given in the problem:
466 = k * 8 * 12
Solving for k:
k = 466 / (8 * 12) = 4.875
So the formula is:
Number of applications = 4.875 * (number of workers) * (number of hours)
b) If 3 workers are sick, then 8 - 3 = 5 workers are left. To find how long they will have to work to assemble 466 applications, we can again use the formula:
466 = 4.875 * 5 * (number of hours)
Solving for the number of hours:
number of hours = 466 / (4.875 * 5) = 19.07 hours (rounded to two decimal places)
So the remaining workers will have to work for approximately 19.07 hours to assemble 466 applications.
c) If the task has to be accomplished in 4 hours, we can again use the formula with the new values:
466 = 4.875 * (number of workers) * 4
Solving for the number of workers:
number of workers = 466 / (4.875 * 4) = 23.97
Since we cannot have a fraction of a worker, we need to round up to the nearest whole number of workers.
Therefore, we would need to hire 24 temporary workers to accomplish the task in 4 hours.

if the researcher knows that the mean is 60 and the standard deviation is 6, then the majority of the scores falling between 1 or -1 standard deviation of the mean fall between:
If the researcher knows that the mean is 60 and the standard deviation is 6, then it can be concluded that the majority of the scores will fall within 1 standard deviation above or below the mean. This is because the standard deviation is a measure of how spread out the data is from the mean.
In this case, a standard deviation of 6 means that the majority of the scores will fall between 54 and 66 (60 plus or minus 6). This also means that approximately 68% of the scores will fall within this range. However, it's important to note that there will still be some scores outside of this range. The standard deviation of the mean can be calculated by dividing the standard deviation by the square root of the sample size. This value will indicate the variability of the sample means.

Over the past 4 years, a customer's fixed income portfolio value has dropped by 5%. During the same period, the Consumer Price Index has dropped by 2%. Based on these facts, which statement is TRUE?
The statement that is TRUE based on the given facts is that the customer's fixed income portfolio has experienced a greater decline in value than the decrease in the Consumer Price Index (CPI).
To elaborate, the customer's fixed income portfolio has dropped by 5% over the past 4 years. This means that the value of their portfolio has decreased by 5% compared to its initial value. On the other hand, the Consumer Price Index (CPI) has dropped by 2% during the same period. The CPI is a measure of inflation and represents the average change in prices of goods and services.
Since the customer's portfolio has experienced a decline of 5%, which is larger than the 2% drop in the CPI, it indicates that the value of their portfolio has decreased at a higher rate than the general decrease in prices. In other words, the purchasing power of their portfolio has been eroded to a greater extent than the overall decrease in the cost of goods and services measured by the CPI.

The function f is defined for all x in the closed interval [a,b]. If f does not attain a maximum value on [a,b], which of the following must be true?
answer choices
O f is not continuous on [a,b].
O f is not bounded on [a,b].
O f does not attain a minimum value on [a,b].
O The graph of f has a vertical asymptote in the interval [a,b].
O The equation f'(x) = 0 does not have a solution in the interval [a,b].
If f does not attain a maximum value on [a,b], then the function does not attain a maximum value. The option "f does not attain a minimum value on [a,b]" must be true.
What is a maximum value?A maximum value is the highest value of a function, that is, the largest y-value of a graph. For example, f(x) = x² has a maximum value of infinity because the parabola opens upwards, and its value keeps increasing infinitely. Therefore, the highest value it attains is infinite.
How does it relate to the problem?If f does not attain a maximum value, then there is no highest value, meaning that the value of the function increases indefinitely. In that case, there must not exist a minimum value, since the function keeps rising indefinitely without any upper bound. Hence, f does not attain a minimum value on [a,b].
Option C must be true, which is: O f does not attain a minimum value on [a,b].
