Fill in the blanks below in order to justify whether or not the mapping shown represents a function.

Answers

Answer 1

The mapping shown does not represents a function

Determining if the mapping is a function

From the question, we have the following parameters that can be used in our computation:

The mapping

From the mapping, we have

(1, 7), (8, 3), (8, -1) and (3, 0)

The above ordered pair is not a function

This is so because the input value 8 have different output values 3 and -1

i.e. it would not pass the vertical line test when represented on a graph

Answers

(I've done this assigment so here are all the answers.)

Answer :

Q1. f'(x)=-20x+4. When x=11, this is f'(11)=-20×11+4=-220+4=-216.

Q2. Lim(x➝4) of x²+3x-1. The expression can be evaluated by direct substitution without constraints: 16+12-1=27.

Q3. The derivative is 7 for all values of x because the function is linear with a constant slope.

Q4. The function is piecewise. We need the conditions that apply when x is close to zero. We need to look at x approaching from the negative side and the positive side. If the limits are not the same the limit does not exist. So, when x<0 we use 7-x². When x is just less than zero, this left-hand limit is 7. When x>0 we use 10x+7. When x is just bigger than zero, this right-hand limit is 7. We are not interested in x=0, we are only interested in the left- and right-hand limits, which happen to be the same. So the limit is 7.

Q5. f'(x)=-3/x². f'(1)=-3.

Q6. In all limit questions, you can always ignore what happens when x=limit, because it’s the approaches that matter. So x➝2⁻ means look at the graph on the left of the limit. The horizontal line at y=4 means the left limit is 4. x➝2⁺ means look at the graph on the right of the limit. This is where y=-3, so the right limit is -3. The answer is 4 and -3 for left and right limits respectively.

Q7. First find left and right limits: x➝-1⁻: use x<-1: f(x)=x+1, so left limit is 0; x➝-1⁺: use x>-1: f(x)=1-x: so right limit is 1-(-1)=2. The left and right limits are different, so the limit does not exist.

Q8. 1/(x-7). When x=7, this quantity is not defined and this is a vertical asymptote. When x➝7⁻ we can use a value of x slightly less than 7 and see what happens. First try x=6.99, then 1/(x-7)=-100. Now try x=6.999, then we get -1000. So it’s getting larger in magnitude, and it’s negative. An infinitely large negative value is -∞. So the limit as x approaches 7 from the left is -∞.

Q9. Ignore the closed point at (3,7). For x➝3⁻, we are on the sloping line, so the limit is 1.5.

Q10. As x approaches zero the numerator approaches 1. The denominator gets smaller so its reciprocal gets larger, and it can be positive or negative depending on how we approach zero. So we can’t define the limit, so it doesn’t exist.

Q11. Derivative is -(-3/x²)=3/x². When x=-4, this is 3/16, because (-4)²=16.

Q12. x²-2➝-2 when x➝0.

Q13. (x²-16)/(x-4)=(x-4)(x+4)/(x-4)➝x+4 because the common factor x-4 cancels. Note that the quantity does not exist at precisely x=4 but in the limit it approaches x+4=8 when x=4. So the answer is 8 for the limit.

Q14. The derivative is constant -13 and is independent of t, so the instantaneous velocity is -13.

Q15. 1/(x-2)² is always positive, so it doesn’t matter whether we look at the left or right limits. The result as x➝2 is ∞, which is an undefinable quantity. x=2 is a vertical asymptote.

Answers

Step-by-step explanation:

1 and 2 are taken away, therefore you have 3, 4, 5, and 6 left as options to roll. So the answer is 4/6 since there's 4 numbers, but simplified it's 2/3.

Answer:

There are six possible outcomes when rolling a die, each of which is equally likely. Of these six outcomes, three are greater than 2 (3, 4, 5) and three are not (1, 2, 6). Therefore, the odds in favor of rolling a number greater than 2 are 3 to 3, or simply 1 to 1. Alternatively, we could express this as a probability: the probability of rolling a number greater than 2 is 3/6, or 1/2, since there are three favorable outcomes out of a total of six possible outcomes.

the number of days, d, that it will take to run a marketing campaign is given by d = 192/n where n is the number of people needed each day. alex’s company will take 32 days to run the campaign. shay’s company will take 24 days to run the campaign. shays company will have to use more people each day than alex’s company. how many more?

Answers

Answer:

2 more people each day.

Step-by-step explanation:

We are given the following relation:

$d = \frac{192}{n}$

In which d is the number of days that will take to run a marketing campaign with n people.

Alex’s company will take 32 days to run the campaign.

So the number of people in his campaign is given by:

$32 = \frac{192}{n}$

$32n = 192$

$n = \frac{192}{32}$

$n = 6$

Shay’s company will take 24 days to run the campaign.

So the number of people in her campaign is given by:

$24 = \frac{192}{n}$

$24n = 192$

$n = \frac{192}{24}$

$n = 8$

Shays company will have to use more people each day than alex’s company. how many more?

8 - 6 = 2

26. The graph shows a polynomial function f. Polynomial function g=x^2(6-x). Compare the maximum values and the end behavior of the functions f and g when x>0

Answers

The end behavior of the polynomial is, rises to the left and falls to the right.

What is end behavior of polynomial?

A polynomial function typically behaves at its end in the same way that its leading term, or the term with the largest exponent, does at its end.

Look at the leading term of the polynomial function to understand its end behavior. Given that the leading term has the highest power, its behavior will dominate the graph because it will grow much more quickly than the other terms as x gets very large or very small.

Consider, the given polynomial g(x) = x^2 (6 - x)

From the graph of the polynomial function we can see that the maximum point of the polynomial is at its vertex.

The vertex of the polynomial is (10, 90).

So this is the maximum value of the function is (10, 90).

Now to find the end behavior of the polynomial.

The degree of the polynomial is 3 and the leading coefficient of the polynomial is, -1.

By using: Odd degree and Negative leading coefficient the graph Rises to the left and falls to the right.

Hence, the end behavior of the polynomial is, rises to the left and falls to the right.

x + 3y = 38
x + 6y = 53

Answers

Answer: 5968430.999

Step-by-step explanation:

Answer:

(x, y) = (23, 5)

Step-by-step explanation:

To solve this system of equations, we can use the method of substitution or elimination.

Substitution Method:

We can solve for x in the first equation, then substitute it into the second equation:

x + 3y = 38 => x = 38 - 3y

Substituting x into the second equation, we get:

(38 - 3y) + 6y = 53

Simplifying this equation, we get:

3y = 15

y = 5

Substituting y back into the first equation, we get:

x + 3(5) = 38

x + 15 = 38

x = 23

Therefore, the solution to the system of equations is (x, y) = (23, 5).

The ratio of the length of a rectangle to its width is 4 1/2 : 2 1/4. What is the unit rate of the length per width of the rectangle?

Answers

Answer:

The ratio simplifies fully to 2:1

=======================================================

Work Shown:

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

2 & 1/4 = 2 + 1/4 = 2 + 0.25 = 2.25

The original ratio is the same as 4.5 : 2.25

Divide both parts by 2.25 and you'll end up with 2:1

4.5/2.25 = 2

2.25/2.25 = 1

This means the length is twice as long compared to the width.

Income tax payable refers to a business organization's tax liability to the government in the jurisdiction in which it operates. The amount of liability will be determined by the company's profitability over a given time period and the applicable tax rates. Tax payable is considered a current liability rather than a long-term liability because it must be settled within the next 12 months.

Based on the table, we are using the tax rate of 15% for the taxable income of $11,757.

The tax payable will equals to:

= 15%*$11,757 + $927.50

The Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random. Given that the stamp chosen is from the 20th century, what is the probability it is British?

Answers

The probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

What is the Venn diagram?

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

f = 100 stamps in the collection

A = stamps in the 20th century

B = British stamps

We can make a linear equation to solve for x as the total stamps are 100 in the collection.

$\rm x(x-6)+x+2x+32= 100\\\\\rm x^2-6x+x+2x+32 = 100\\\\\rm x^2-3x-68 = 0$

After solving x = 9.88, or x = -6.88

Probability can't be negative so neglecting the negative ones

x = 9.88

The probability that it is British:

$=\rm \frac{x +2x + 32}{100}$

$=\rm \frac{9.88 +2(9.88) + 32}{100}$

= 61.64/100

= 0.6164

Thus, the probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

The distance from our house to the grocery store is five and one quarter kilometres.The distance from our house to the mall is ten and three quarter kilometres .How much further is the mall than grocery store from our house?

Answers

After subtracting the given two distances, It can be obtained that the mall is five and a half kilometers further than the grocery store from the house.

How to find the distance between two points?

If there are three points $A, B, C$ and the distance between $A$ and $B$ is $d_1$ and the distance between $A$ and $C$ is $d_2$. Also, $d_2 > d_1$. Then the distance between $B$ and $C$ can be obtained by subtraction $d=d_2-d_1$.

Given that the distance from the house to the grocery store is five and one-quarter kilometers i.e., $d_1=5.25$ km and the distance from the house to the mall is ten and three-quarter kilometers i.e., $d_2=10.75$ km.

So, the distance from the grocery store to the mall is $d=d_2-d_1=10.75-5.25=5.5$ km.

Therefore, after subtracting the given two distances, we can conclude that the mall is five and a half kilometers further than the grocery store from the house.
