Answer:
2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a , b ] is
\(\frac{f(b)-f(a)}{b-a} \)
Here [ a, b ] = [ - 1, 3 ] , then
f(b) = f(3) = 3² + 1 = 9 + 1 = 10
f(- 1) = (- 1)² + 1 = 1 + 1 = 2
average rate of change = \(\frac{10-2}{3-(-1)} \) = \(\frac{8}{3+1} \) = \(\frac{8}{4} \) = 2

For which situation does one quantity change at a constant rate per unit interval relative to another quantity?
Responses
For every day that passes, a person drives 54 miles.
.
For every month that passes, a savings account earns interest at a rate of 1.5%
For every week that passes, a vine doubles in length 2 times a week.
.
For every year that passes, a population of insects increases by 6%
Answer:
(a) For every day that passes, a person drives 54 miles
Step-by-step explanation:
You want to know the situation in which one quantity changes relative to another at a constant rate.
DrivingThe rate of change is described as 54 miles for each day. This is a constant rate of change. Miles relative to days are described by a linear function.
SavingsWe assume the description means that the balance in the savings account increases by 1.5% with each passing month. While this interest rate is a constant, the amount by which the balance changes each month is not constant. The balance relative to time is described by an exponential function.
VineIf the vine doubles in length twice a week, its length increases by 300% each week. As with savings, this growth rate is constant, but the amount of growth each week is not. The length of the vine is described by an exponential function.
PopulationAs with savings, this growth rate is constant, but the amount of increase each year is not. The population is described by an exponential function.
The situation with a constant rate of change is ...
For every day that passes, a person drives 54 miles.
__
Additional comment
When the quantity is graphed, the "rate of change" refers to the slope of the curve on the graph. The graph of an exponential growth function does not have a constant slope, but has a slope that increases exponentially.

Suppose that an angle is bisected to form two smaller angles that measure (3+30)° and (5+6)° . What is the measure of the original angle?
°
Based on the angles addition theorem, the measure of the original angle = 44°.
What is the Angles Addition Theorem?The angles addition theorem states that if an angle is bisected to form two smaller angles, then the sum of the measures of the two smaller angles equals the measure of the original angle that is bisected.
Given that the two smaller angles formed when bisected are: (3+30)° and (5+6)°. Based on the angles addition theorem:
The measure of the original angle = (3+30)° + (5+6)°
The measure of the original angle = 33° + 11°

Excel wants to increase the productivity of its line workers. four different programs have been suggested to help increase productivity. twenty employees, making up a sample, have been randomly assigned to one of the four programs and their output for a day's work has been recorded. you are given the results in the file name ahmadi. State the null and alternative hypotheses.
The null hypothesis would be that there is no significant difference in productivity between the four programs. The alternative hypothesis would be that there is a significant difference in productivity between at least two of the programs.
In this scenario, Excel is trying to increase the productivity of its line workers and is testing four different programs. A sample of twenty employees has been randomly assigned to one of the programs, and their daily output has been recorded in the file named "ahmadi." We will use these data to determine if any of the programs are effective in increasing productivity. The null and alternative hypotheses can be stated as follows:
Null Hypothesis (H0): There is no significant difference in productivity between the four programs. In other words, none of the programs have a meaningful impact on the productivity of the line workers.
Alternative Hypothesis (H1): At least one of the four programs has a significant impact on the productivity of the line workers, leading to increased output compared to the other programs.
To test these hypotheses, you would typically perform an analysis of variance (ANOVA) on the data provided in the "ahmadi" file. If the ANOVA result is significant, you would reject the null hypothesis and accept the alternative hypothesis, indicating that at least one program effectively increases productivity.

a quality control inspector has drawn a sample of 17 light bulbs from a recent production lot. suppose 30% of the bulbs in the lot are defective. what is the probability that between 3 and 6 (both inclusive) bulbs from the sample are defective? round your answer to four decimal places.
Answer: This is a binomial distribution problem with parameters n = 17 and p = 0.3, where n is the sample size and p is the probability of a defective bulb. We need to find the probability that between 3 and 6 (both inclusive) bulbs from the sample are defective.
Let X be the number of defective bulbs in the sample. Then X has a binomial distribution with parameters n = 17 and p = 0.3, i.e., X ~ B(17, 0.3).
We want to find P(3 ≤ X ≤ 6). Using the binomial probability formula, we have:
P(3 ≤ X ≤ 6) = P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)
= (17 choose 3)(0.3^3)(0.7^14) + (17 choose 4)(0.3^4)(0.7^13) + (17 choose 5)(0.3^5)(0.7^12) + (17 choose 6)(0.3^6)(0.7^11)
≈ 0.1566 (rounded to four decimal places)
Therefore, the probability that between 3 and 6 (both inclusive) bulbs from the sample are defective is approximately 0.1566.

There is need to design an observer for real operation. The analysis and design tasks are listed below. a) Discuss in what situation it needs for introducing the observer and what the role of each matrix of (L, M, and N) is in the observer. (the words limit is 80) b) From det[s1 - L], discuss why specify the observer poles with s, = -4 s, =-5 against the plant dynamics. (the words limit is 40) c) Design the state observer with the specified poles s =-4 =-5. d) Show the designed observer block diagram with matrices (L, M, and N)
a) Situations when an observer needs to be introduced and the role of each matrix: In order to observe the state of a system in practice, an observer must be introduced. The observer's role is to assess the system's state variables based on the system's input and output values, as well as the system's dynamics. The observer consists of three matrices:L: State feedback gain matrix M: Determines the observer's internal dynamics N: Maps the output signal to the observer's inputThe purpose of the observer is to estimate the system's states so that they can be fed back into the control loop.
b) Det[s1 - L] discussion: When designing an observer, the choice of observer poles has a significant impact on the system's efficiency. If the observer poles are placed far too close to the system poles, the observer may become unstable and diverge from the true state values. Alternatively, if the observer poles are placed far too far from the system poles, the observer may not be sensitive enough to changes in the system's states.In this context, det[s1 - L] refers to the determinant of the system's matrix minus the state feedback gain matrix. To ensure that the observer's poles are not too close or too far from the system's poles, this determinant must be non-zero.
c) Designing state observer: The observer's gain matrix L can be determined using the Ackerman formula.
By using Ackerman formula, the observer gain matrix is:L = acker(A', C', [s1, s2])L = [21 12]s1 = -4; s2 = -5 The observer's matrix M is given by:M = A - LC = [0 1;-1 -2] - [21; 12][1 0]M = [-21 -12;-21 -8]

Simplify each complex fraction. 2/x+4 + 2 / 1 + 3 / x+4
The simplified form of the complex fraction is (4x + 14) / (x + 5).
To simplify the complex fraction, we need to combine the fractions in the numerator and denominator. The given complex fraction is 2 / (x + 4) + 2 / (1 + 3 / (x + 4)).
In the first step, let's simplify the denominator of the second fraction in the numerator. 3 / (x + 4) can be rewritten as 3 / 1 * 1 / (x + 4), which is equal to 3 / (x + 4).
Now, we can combine the fractions in the numerator by finding a common denominator. The common denominator is (x + 4). Multiplying the first fraction by (1 + 3 / (x + 4)) / (1 + 3 / (x + 4)) and the second fraction by (x + 4) / (x + 4), we get (2 * (1 + 3 / (x + 4)) + 2 * (x + 4)) / (x + 4).
Expanding and simplifying the numerator, we have (2 + 6 / (x + 4) + 2x + 8) / (x + 4).
Combining like terms in the numerator, we get (4x + 14) / (x + 4).
Therefore, the simplified form of the complex fraction is (4x + 14) / (x + 4).

what is interval notation example ?
Interval notation is a way of representing a range of values on a number line. It is written using brackets and parentheses to indicate whether the endpoints are included or excluded from the interval.
For example, the interval notation for the range of values between 1 and 5 (inclusive) would be [1, 5]. The square brackets indicate that both 1 and 5 are included in the range.
If the endpoints are excluded, we use parentheses. For instance, the interval notation for the range of values between 1 and 5 (excluding 1 and 5) would be (1, 5).
In general, we use square brackets for closed intervals (where the endpoints are included) and parentheses for open intervals (where the endpoints are excluded).
