How to obtain the function?

The parent function in this problem is defined as follows:

\(f(x) = \sqrt{x}\)

For the vertical shrink by a factor of 1/6, the function is multiplied by 1/6, hence it is given as follows:

\(g(x) = \frac{1}{6}\sqrt{x}\)

For the translation left 3 units, we have that x -> x + 3, hence:

(i) Write the zeroes of the polynomial by using above graph. (ii)Form a quadratic polynomial for above

Answers

There is no real Value of k that will satisfy the equation 2x² - x + 8k = 0 if a and 1/a are the roots of the polynomial.

(i) Zeroes of the polynomial:

In the graph, we have two points where the curve intersects the x-axis: one is at (-1,0), and the other is at (2,0).The corresponding values of x are -1 and 2, and they are the zeros of the polynomial. Therefore, the zeros of the polynomial are -1 and 2.(ii) Forming the quadratic polynomial:

From the graph, we can observe that the curve intersects the y-axis at the point (0,5), implying that the constant term of the polynomial is 5.

We can use the formula to find the quadratic polynomial if we have two zeros and one constant term. Thus, the quadratic polynomial is given by:(x + 1)(x - 2) = x² - x - 2x + 2 = x² - 3x + 2. Therefore, the quadratic polynomial is x² - 3x + 2.(iii) Value of k if a, 1/a are the zeroes of the polynomial 2x² - x + 8k:

We know that a and 1/a are the zeroes of the polynomial 2x² - x + 8k. Therefore, we can find the sum and product of the roots and use them to determine the value of k.

The sum of the roots is a + 1/a, and their product is a(1/a) = 1. Using the sum and product of the roots, we can write: a + 1/a = 1/2 (1/2 is the coefficient of x)Substituting a with 1/a in the above equation, we get: 1/a + a = 1/2Multiplying both sides of the equation by 2a, we get: 2 + 2a² = a

Simplifying the equation, we get: 2a² - a + 2 = 0Multiplying both sides by 2,

we get: 4a² - 2a + 4 = 0Dividing both sides by 2, we get: 2a² - a + 2 = 0

Using the quadratic formula, we get: a = [1 ± √(1 - 4(2)(2))]/(2(2))

Simplifying, we get: a = [1 ± √(-31)]/4Since the discriminant of the quadratic formula is negative, the roots are imaginary. Therefore, there is no real value of k that will satisfy the equation 2x² - x + 8k = 0 if a and 1/a are the roots of the polynomial.

Suppose five officials O1, O2, O3 , O4 , O5 are to be assigned five different city
cars: an Escort, a Lexus, a Nissan, a Taurus, and a Volvo. O1 will not drive an
Escort or a Nissan; O 2 will not drive a Taurus; O3 will not drive a Lexus or a
Volvo; O 4 will not drive a Lexus; and O5 will not drive an Escort or a Nissan. If
a feasible assignment of cars is chosen randomly, what is the probability that
(a) O1 gets the Volvo?
(b) O2 or O5 get the Volvo? (Hint: Model this constraint with an altered board.)

Answers

(a) The probability that O1 gets the Volvo is  3/10 .

(b) The probability that O2 or O5 will get the Volvo is 1/2  .

In the question ,

it is given that ,

the five officials : O1, O2, O3 , O4 , O5 are to be assigned five different city cars: a Escort,  Lexus,  Nissan, the Taurus, and the Volvo .

From the given data , the table formed is shown below .

From the table , we can observe that ,

O1 will not drive the Escort or a Nissan . So, he has chance of getting one car among Lexus, Taurus & Volvo = 3 possibilities

O2 will not drive the Taurus​ . So, he has chance of getting one car among Escort , Nissan ,Lexus, & Volvo = 4 possibilities

O3 will not drive the Lexus or Volvo​ . So, he has chance of getting one car among Escort , Nissan ,Taurus = 3 possibilities

O4 will not drive the Lexus so he has chance of getting one car among Escort , Nissan ,Taurus, Volvo = 4 possibilities

O5 will not drive the Escort or a Nissan . So, he has chance of getting one car among Lexus, Taurus & Volvo = 3 possibilities .

The  20 possible arrangements for E,L,N,T,V are :

{ (O2, O1, O3, O4, O5),  (O2, O1, O3, O5, O4),  (O2, O1, O4, O3, O5),  

(O2, O5, O3, O1, O4),  (O2, O5, O3, O4, O1),(O2, O5, O4, O3, O1),  

(O3, O1, O2, O4, O5),  (O3, O1, O2, O5, O4),  (O3, O1, O4, O5, O2),  

(O3, O2, O4, O1, O5), (O3, O2, O4, O5, O1),  (O3, O5, O2, O1, O4),  

(O3, O5, O2, O4, O1),  (O3, O5, O4, O1, O2),  (O4, O1, O2, O3, O5),

(O4, O1, O3, O5, O2),  (O4, O2, O3, O1, O5),  (O4, O2, O3, O5, O1),  

(O4, O5, O2, O3, O1),  (O4, O5, O3, O1, O2)  }

Part(a)  : The probability that O1 gets the Volvo is = 6/20 = 3/10 .

and

Part(b) :

Probability of O2 or O5 gets the Volvo = (Probability of O2 getting Volvo
) + (Probability of O5 getting Volvo) .

= 4/20 + 6/20

= 10/20 = 1/2 .

Therefore , the required probability for (a)  is 3/10 and for (b) is 1/2  .

The temperature at midnight was -8°C. The temperature at 5 am was -3°C. (a) Work out the difference between the two temperatures. (b) The temperature at midday was 9°C higher than the temperature at 5 am.. Work out the temperature at midday.​

Answers

a) The difference between the temperatures is 5°c.

b) We will see that at midday, the temperature is 12°C.

How to find the differences between the temperatures?

We know that at midnight the temperature was T = -8°C, and at 5am the temperature was T' = -3°C.

a) First we want to find the difference between the temperatures, we can compute that directly:

T' - T = -3°C - (-8°C) = 5°C

This means that the temperature increased 5°C in that time interval.

b) At midday, the temperature was 9°C higher than at 5am, this means that:

T'' - T' = 9°C

T'' - 3°C = 9°C

Now we can solve this for T''

T'' = 9°C + 3°C = 12°C

At midday, the temperature is 12°C.

John can change four tires on a car
in a half hour. How many tires can
he change in 6 hours? How many
cars is that? How long does it take
John to change one tire?

Answers

Answer:
In 6 hours John can change 48 car tires
That is 12 cars
It takes 7 minutes and 39 seconds to change a car tire

Explanation:
4x12=48
48/4=12
30/4=7.5
Take the 4 tires he changed and multiply it by two.

In one hour he can change 8 tires

8 tires times 6 hours is 48

He changes 48 tires in 6 hours.

Divide 48 by 4 because there are at least 4 tires on a car

That gives you 12

So he changed the tires of 12 cars in 6 hours.

To find the time of one tire you would take 30 min and divide it by 4. Because it takes 30 minutes to change 4

That gives you 7.5

So 7 minutes and 30 seconds to change one tire


How many can he change in 6 hours?
4x2=8 8x6=48 tires

How many cars is that?
48 divided by 4=12

How long for one tire?

30 divided by 4= 7.5 minutes

How much would you need to deposit in an account now in order to have $2000 in the account in 5 years? Assume the account earns 5% interest compounded monthly.

Answers

I need to deposit $1558.41 to have $2000 in the account in 5 years.

What is compound interest?

The interest charged on a debt or deposit is known as compound interest. It is the idea that we use the most regularly. Compound interest is calculated for a sum based on both the principal and cumulative interest.

    ∴ Compound interest = P(1 + \(\frac{r}{100*12}\))ⁿ  (∵ for monthly interest)

        P = Principal

        r = rate of interest per month

        n = number of months

Given:

r = 5% per month

n = 5 years = 5*12 = 60 months

  CI = P (1+5/(12 * 100))⁶⁰

2000 = P(1.0041)⁶⁰

2000 = P(1.2834)

      P = 1558.41

Therefore, the amount required to deposit is 1558.41 dollars to get 2000 dollars after 5 years with 5 percent interest per month.

An interesting rectangular box is one whose sides have integer lengths, and which has the property that it’s surface area is numerically equal to its volume. Find the dimensions of all interesting rectangular boxes.

Answers

Therefore, the only interesting rectangular box has dimensions 3 x 3 x 6.

What is area?

Area is a measure of the size of a two-dimensional surface or region, typically expressed in square units, such as square meters or square feet. It is the extent or measurement of a surface or region, often described as the amount of space inside the boundaries of a two-dimensional shape.

Here,

Let's assume the dimensions of the rectangular box are a, b, and c, where a is the length, b is the width, and c is the height. We can set up the equation:

2ab + 2ac + 2bc = abc

Simplifying, we get:

2(ab + ac + bc) = abc

Dividing both sides by 2abc, we get:

1/a + 1/b + 1/c = 1/2

Since a, b, and c are integers, we know that each of them must be greater than or equal to 2. Without loss of generality, assume that a ≤ b ≤ c. Then, we have:

1/a + 1/b + 1/c ≤ 3/a

Therefore:

3/a ≥ 1/2

So, a ≤ 6. Let's try each value of a from 2 to 6:

a = 2: 1/b + 1/c = 1/4, so b + c = 4b c. We can see that there are no integer solutions for b and c in this case.

a = 3: 1/b + 1/c = 1/2, so b + c = 2b c. The only integer solution is b = 3, c = 6, so the dimensions are 3 x 3 x 6.

a = 4: 1/b + 1/c = 3/8, so b + c = 8b c/3. There are no integer solutions for b and c in this case.

a = 5: 1/b + 1/c = 3/10, so b + c = 10b c/3. There are no integer solutions for b and c in this case.

a = 6: 1/b + 1/c = 2/9, so b + c = 9b c/2. There are no integer solutions for b and c in this case.

What is the probability that a random sample of 400 U.S. youth will provide a sample proportion (p¯) that is within 0.03 of the population proportion (p)?

Answers

Complete Question

The proportion of adult women in the United States is 51% (p=0.51).What is the probability that a random sample of 400 U.S. youth will provide a sample proportion (p¯) that is within 0.03 of the population proportion (p)?

Answer:

The probability is  \(P( 0.48 < p < 0.54 ) = 0.77\)  or  \(P( 0.48 < p < 0.54 ) = 77\%\)

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  400

    The population proportion is  p = 0.51

Generally the standard deviation of this sampling distribution is mathematically represented as

          \(\sigma = \sqrt{\frac{p(1-p)}{n} }\)

=>      \(\sigma = \sqrt{\frac{0.51(1-0.51)}{400} }\)

=>      \(\sigma = 0.02499\)

Generally the lower limit for the range of the population proportion within 0.03 is

    \(a = p - 0.03\)

=>\(a = 0.51 - 0.03\)

=>\(a = 0.48\)

Generally the  upper  limit for the range of the population proportion within 0.03 is

    \(b = p + 0.03\)

=>\(a = 0.51 + 0.03\)

=>\(a = 0.54\)

Generally the  probability that a random sample of 400 U.S. youth will provide a sample proportion (p¯) that is within 0.03 of the population proportion (p) is mathematically represented as

     \(P( a < p < b) = P( \frac{a - p }{\sigma } < \frac{\^ p - p }{\sigma} < \frac{b - p}{\sigma } )\)

=>   \(P( 0.48 < p < 0.54 ) = P( \frac{0.48 - 0.51 }{0.02499 } < \frac{\^ p - p }{\sigma} < \frac{0.54 - 0.51}{0.02499 } )\)

\(\frac{\^ p -p }{\sigma }  =  Z (The  \ standardized \  value\  of \  \^ p )\)

=>   \(P( 0.48 < p < 0.54 ) = P( -1.2 < Z < 1.2 )\)

=>   \(P( 0.48 < p < 0.54 ) = P( Z < 1.2) - P(Z < -1.2 )\)

From the z table  the area under the normal curve to the left corresponding to  1.2 and  -1.2  is

     \(P( Z < 1.2) =0.88493\)

and  

    \(P( Z < -1.2) =0.11507\)

So

   \(P( 0.48 < p < 0.54 ) = 0.88493 - 0.11507\)

=>  \(P( 0.48 < p < 0.54 ) = 0.77\)

To compare the prevalence of HIV and associated factors for participating HIV voluntary counseling and testing (VCT) among older clients of fernale sexworkers (CFSWs) in Luzhou City and Fuyang City in China. Methods. A cross-sectional study was conducted and the study employed 978 male CFSWs, aged 50 years and above from October 2016 to December 2017. AIl participants were required to complete a questionnaire and provide blood samples for HiV testing. Multivariate logistic regression analysis was used to analyze theinfluential factors of using VCT program and tested for HIV. Results. The HIV infection prevalence rate was 1.2% and 0.5%, while 52.3% and 54.6% participants had ever utilized VCT service and tested for HIV in Luzhou City and Fuyang City, respectively. The older CFSWs who ever heard of VCT program were more likely to uptake VCT program in both cities 0. Participants, whose marital status was married or cohabiting O, who have stigma against individals who are living with HIV/AIDS O, whose monthly income is more than 500 yuan 0. and whose age is more than 60 years old O, were less likely to visit VCT clinks. Those who are worried about HIV infected participants were more likely to utilize VCT services inFuyang City O, Conclusion: Combine strategy will be needed to promote the utilization of VOl service, based on the socioeconomic characteristics of older male CFSWs in differentcities of ChinaThe study measures?
