Use the relevant information to compute the derivative of h(x)=f(g(x)) at x =1, where f(1) = 0, g(1)=2,f' (2)=3, g' (1) = 4, and g '(3) = -4.
h' (1)= ______

Answers

Answer 1

The derivative of h(x) at x = 1 is 12.

For a function y=f(u) and u=g(x), the derivative of y with respect to x is \(dy/dx=dy/du * du/dx\). Here, \(u = g(x)\) and \(y = h(x)\), so \(dy/dx=dh/du * du/dx.\)

Given that \(h(x)=f(g(x))\) => \(u = g(x)\) and \(y = f(u)\). Then, \(h'(1) = f'(g(1)) * g'(1)h'(1) = f'(2) * 4\). Hence, \(h'(1) = 3 * 4 = 12\). So, the derivative of h(x) at x = 1 is 12. Therefore, the correct option is (D) 12.

Find the surface area of the figure. Hint: the surface area from the missing prism inside the prism must be ADDED!

Answers

To find the surface area of the figure, we need to consider the individual surfaces and add them together.

First, let's identify the surfaces of the figure:

The lateral surface area of the larger prism (excluding the base)

The two bases of the larger prism

The lateral surface area of the smaller prism (excluding the base)

The two bases of the smaller prism

The lateral surface area of a prism is given by the formula: perimeter of the base multiplied by the height.

The bases of the prisms are rectangles, so their areas can be calculated by multiplying the length by the width.

To find the missing prism's surface area, we need to consider that it is a smaller prism nested inside the larger prism. The lateral surface area and bases of the missing prism should also be included.

Once we have calculated the individual surface areas, we add them together to find the total surface area of the figure.

#SPJ11

It will take about 30.8 years for the total to reach $1,000,000. The exponential function that represents the situation.

When Mario invested $280 at 8% interest compounded continuously is given by:

\(A(t) = a * e^{(rt)\)

where

A(t) represents the total amount of money after t years,

a represents the initial investment,

e is the base of the natural logarithm,

r is the annual interest rate, and

t represents the number of years elapsed.

Substituting the given values into the formula,

\(A(t) = 280 * e^{(0.08t)\)

Now, we need to find out at what time the total will reach $1,000,000.

So we can write the equation in this form:

1,000,000 = 280 * \(e^{(0.08t)\)

Dividing both sides by 280, we get:

\(e^{(0.08t)\) = 1,000,000 / 280

\(e^{(0.08t)\) = 3571.42857

Taking natural logarithm on both sides,

we get: 0.08t = ln 3571.42857

t = ln 3571.42857 / 0.08

t ≈ 30.8

Consider the first question,

We need to find the roots of given equation (3x + 7)(2x - 5) = 0

From above equation we can say that either 3x + 7 = 0 or 2x - 5 = 0

of 100 patients selected at random from a clinic, 33 were found to have high blood pressure. construct a 95% confidence interval for the percentage of all patients at this clinic that have high blood pressure.

Answers

We can say with 95% certainty that the genuine rate of all patients at this clinic who have high blood pressure is between 24% and 42%. 

To develop a 95% certainty interim for the rate of all patients at this clinic that have tall blood weight, we will utilize the equation:

CI = p ± z*(p*(1-p)/n))

where p is the sampling extent, z is the z-score related to the required certainty level (in this case, 1.96 for 95% certainty), and n is the test measure.

We are given that out of a test of 100 patients, 33 have high blood weight. In this manner, the test extent is:

p = 33/100 = 0.33

Utilizing the equation over, we will calculate the edge of the mistake:

Arduino

ME = z*(p*(1-p)/n)) = 1.96*(0.33*(1-0.33)/100)) ≈ 0.09

At that point, we are able to develop the 95% certainty interim:

CI = p ± ME = 0.33 ± 0.09 = (0.24, 0.42)

February 1,420
March 1,380
a. Apply four period moving average forecast method to calculate demand for the month of April 2020?
b. What should Al Artz Bakery decide to do with capacity? justify your opinion.
c. If the bakery calculated forecasts for all products it makes, would this forecast be more accurate than the one you just d. calculate? justify your opinion.
e. If bakery decides to use qualitative methods, what sources of opinion it could use in these methods?

Answers

A2: a. The four period moving average forecast method is a technique that is used to calculate the demand for a particular month based on the average demand for the previous four months. In this case, to calculate the demand for the month of April 2020, we will take the average of the demand for the months of December, January, February, and March. The formula for this method is:

Four period moving average forecast = (Demand for December + Demand for January + Demand for February + Demand for March) / 4

= (1,450 + 1,410 + 1,420 + 1,380) / 4

= 5,660 / 4

= 1,415

Therefore, the demand for the month of April 2020 is 1,415 loafs.

b. Based on the demand forecast for the month of April 2020, Al Artz Bakery should decide to maintain their current capacity as the demand is relatively stable and there is no significant increase or decrease in demand. This will ensure that they are able to meet the demand without overproducing or underproducing.

c. If the bakery calculated forecasts for all products it makes, the forecast would be more accurate than the one calculated for just one product. This is because it would take into account the demand for all products and would give a more comprehensive view of the overall demand for the bakery.

d. If the bakery decides to use qualitative methods, it could use sources of opinion such as customer feedback, expert opinion, and market research. These sources of opinion can provide valuable insights into the demand for the bakery's products and can help to improve the accuracy of the demand forecast.

The following system of periodic tasks are to be scheduled and executed according to structured cyclic schedule with fixed frame size. (5, 1), (7, 1), (12,0) and (45,9). Determine the appropriate frame size for the given task set?

Answers

The appropriate frame size for the given task set is 140.

The frame size is the length of a time interval in which all the tasks in the system are scheduled to be executed. The frame size must be a multiple of the period of each task in the system.

In this case, the periods of the tasks are 5, 7, 12, and 45. The smallest common multiple of these periods is 140. Therefore, the appropriate frame size for the given task set is 140.

Here is a more detailed explanation of the calculation of the frame size:

The first step is to find the least common multiple of the periods of the tasks. The least common multiple of 5, 7, 12, and 45 is 140.

The second step is to check if the least common multiple is also a multiple of the execution time of each task. The execution time of each task is equal to its period in this case. Therefore, the least common multiple is also a multiple of the execution time of each task.

Therefore, the appropriate frame size for the given task set is 140.

statistics computed for larger random samples are less variable than the statistic computed for smaller random samples

Answers

Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.

This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.

The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.

In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.

Given that the cumulative area of 0.2420, a mean of 0, and a standard deviation of 1, the required z-score has to be determined.We know that the standard normal distribution with mean 0 and standard deviation 1 is denoted as N(0, 1). The inverse normal distribution with a cumulative area of x is the inverse of the normal distribution with cumulative area x. Let z be the z-score corresponding to a cumulative area of x, then we can say that P(Z ≤ z) = x, where P is the cumulative distribution function of the standard normal distribution.

Substituting the given values in the formula, we get:0.2420 = P(Z ≤ z)We need to find the corresponding z-value using inverse normal distribution. Therefore, we take the inverse of the cumulative distribution function, as follows:z = invNorm(0.2420)z = -0.71 (rounded to two decimal places)Thus, the required z-score is -0.71.

The population of bats in a large cave is 130 and is growing exponentially at 20% per year. Write a function to represent the population of bats after tt years, where the monthly rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per month, to the nearest hundredth of a percent.

Answers

The exponential expression for the population of the bat will be \(y = 130(1.2)^x\).


What is an exponential expression?

Powers can be expressed succinctly using exponential expressions. The exponential function can be written as \(y = k^x\). Because 2 is the "base" and 5 is the "exponent," the number 32 can be represented as 2x2x2x2=25.

Given that a large cave has 130 bats, and their population is growing at a rate of 20% per year.

The exponential expression for the population of the bats will be written as:-

\(y = 130(1.2)^x\).

Here, y is the population and x is the number of years.

Therefore, the exponential expression for the population of the bat will be \(y = 130(1.2)^x\).

Answer:

(1) p(x) = 7x³ + 4x² + 6 - 9x⁴

Standard Form: - 9x⁴ +  7x³ + 4x² + 6Degree: 4Leading Coefficient: -9Leading Term: -9x⁴

(2) p(x) = 1 + 3x - 9x⁵

Standard Form:  -9x⁵ +3x + 1Degree: 5Leading Coefficient: -9Leading Term: - -9x⁵

(3) y = 9x² - x³ + x⁹

Standard Form: x⁹ - x³ + 9x²Degree: 9Leading Coefficient:  1    (x⁹ = 1x⁹)Leading Term: x⁹

(4) f(x) = (x +3)(x-2)(x+5)

Standard Form: x³ + 6x² - x - 30Degree: 3Leading Coefficient: 1Leading Term: x³

Step-by-step explanation:

Standard form has terms arranged from the highest to the lowest power

Degree is the highest power

Leading coefficient is the coefficient of the highest term

Leading term is the term containing the highest power

(x + 3) (x - 2)(x + 5)

(x + 3) (x - 2) = x² + x - 6 using the FOIL method
(x² + x - 6)(x +5) = x³ + 6x² -x - 30

Step-by-step explanation:

come on, we explained this already in previous questions. if you understood the explanations there, you should have been able to some that here without any problems.

again, standard form is the sorted polynomial from highest variable exponent to the lowest (as the potential constant at the end represents the x⁰ term).

the leading term is the first term on the left (with the highest exponent).

the leading coefficient is the factor in this leading term.

degree is the highest exponent used in the polynomial (again, given by the leading term).

so, what is still the problem ?

i have a slight problem with your handwriting. it is unclear, if there is 7x³ or 17x³. or 13x or 3x.

1.

p(x) = 17x³ + 4x² + 6 - 9x⁴

now, just sort this from the highest to the lowest exponent.

p(x) = -9x⁴ + 17x³ + 4x² + 6

if it should be 7x³ instead of 17x³, please use 7x³ in the polynomial.

degree = 4

leading coefficient = -9

leading term = -9x⁴

2.

p(x) = 1 + 13x - 9x⁵

again sort from highest to lowest exponent

p(x) = -9x⁵ + 13x + 1

again, if it should be 3x instead of 13x, please use 3x in the polynomial.

degree = 5

leading coefficient = -9

leading term = -9x⁵

3.

y = 9x² - x⁵ + x⁹

remember, y = f(x)

that is the same thing, means the same thing. it just gives the result variable a specific name.

again sort by exponent.

y = f(x) or p(x) or ... = x⁹ - x⁵ + 9x²

degree = 9

leading coefficient = 1

leading term = x⁹

4.

f(x) = (x+3)(x-2)(x+5)

this is really like the other question I just answered.

so, we always multiply 2 terms. that result we multiply by the third term. and if they're are more, then that result with the fourth term, and that with the 5th term,...

I usually start at the left :

(x+3)(x-2) = x² - 2x + 3x - 6 = x² + x - 6

now

(x² + x - 6)((x+5) = x³ + 5x² + x² + 5x - 6x - 30 =

= x³ + 6x² - x - 30

so,

f(x) = x³ + 6x² - x - 30

degree = 3

leading coefficient = 1

leading term = x³
