how can you use a mapping diagram to determine the domain and the range of a relation?

Answers

Step 1: Draw the mapping diagram for the given relation.
Step 2: A relation is a function if each element in the domain is paired with one and only one element in the range.
Step 3: From the mapping diagram, it can be observed that the given relation is not a function as '3' in the domain is paired with two elements - 1 and - 2 in the range and '6' is paired with - 1 and - 2.

  Domain Range
    3   | -1
|

  6    |   -2

The method of using a mapping diagram to determine the domain and the range of a relation is outlined in; Steps 1 to 3 below.

A mapping diagram is one that shows how the elements are paired. Furthermore It is drawn like a flow chart for a function to depict the input and output values.

Now, mapping diagrams consists of two parallel columns. The first column is one that represents the domain of a function while the second column represents the range of the function.

Now the steps in using a mapping diagram to determine the domain and the range of a relation are;

Step 1: Draw the mapping diagram for the given function relation.

Step 2: A relation from the mapping diagram will be tagged as a function if each element in the domain column is paired with only one element in the range column

Step 3: However, if an element in the domain column of the mapping diagram can be paired to than 1 element in the range column, then the relation is said to not be a function.

which statement describes the function below f(x)=2x^3-3x+1

Answers

The given function is f(x)=2x^3+2x^2-x. In this case, the highest degree among the terms is 3. According to the Fundamental Theorem of Algebra, the number of zeros or roots of the equation is equal to the highest degree among the terms. Hence for every value of y, there are 3 equivalent x's. The answer thus is B. It is a many-to-one function.

The ratio is boys to girls is 3:5. If there are 24 boys how many girls are in the class

Anne is comparing savings accounts. One account has an interest rate of 1.2 percent compounded yearly, and one account has an interest rate of 1.2 percent compounded monthly. Which account will earn more money in interest?

Answers

in short and without much fuss

let's say Anne puts "x" amount in the account at 1.2% rate annually, that means after 1 year, she will have "x" + 1.2% of "x", or 1.012x to be exact.

the 1.2% rate, kicks in as the period of a year is met.

now, what if Anne puts it in the monthly compounded type? that means, the compounding period is a month, so after 1 month, she has 1.2% extra, or 1.012x, and after 2 months, she will have 1.2% extra of 1.012x, or 1.012144x, and after 3 months, she will have 1.2% extra of 1.0121x, or 1.012145728x and so on.

anyhow, the shorter the compounding period, the more the 1.2% kicks in, the more accumulation in the account.

Final answer:

An account with an interest rate of 1.2 percent compounded monthly will earn more money than one compounded yearly because of how compound interest works, earning 'interest on interest' throughout the year.

Explanation:

The student's question asks which savings account would earn more money, one with an interest rate of 1.2 percent compounded yearly, or one with the same interest rate but compounded monthly. When interest is compounded, it means the bank pays interest on both the original amount of money and any interest that account has already earned. With compounded interest, you end up earning interest on interest.

For the account with yearly compounding at a rate of 1.2 percent, the formula to calculate the amount after one year would be A = P(1 + r/n)^(nt), where P is the principal amount, r is the annual interest rate (decimal), n is the number of times interest is compounded per year, and t is the time in years. In this case, n is 1 because the interest is compounded annually. Therefore, the amount after one year would be A = P(1 + 0.012/1)^(1×1) or A = P(1.012).

For the monthly compounded account, the same formula applies, but n would be 12 because the interest is compounded monthly. So, the amount after one year would be A = P(1 + 0.012/12)^(12×1).

When you perform these calculations, the account with the monthly compounding will yield a slightly higher amount than the annually compounded account because interest is being added more frequently. Each month's interest is then earning interest in the following months, leading to a process known as 'interest on interest'. Though the difference may not be substantial for small amounts and low interest rates, over longer periods, or with higher rates and balances, the difference can become significant.

What is the sum of the first eight terms of a geometric series whose first term is 3 and whose common ratio is 1/2?

Answers

The answer to this question What is the sum of the first eight terms of a geometric series whose first term is 3 and whose common ratio is 1/2 is (7/65/128)

Answer:

[tex]\frac{765}{128}[/tex]

Step-by-step explanation:

We have been given that 1st term of a geometric series is 3 and common difference is 1/2 . We are asked to find the sum of 1st 8 terms of the given series.

We will use geometric series formula to solve our given problem.

[tex]S_n=\frac{a_1(1-r^n)}{1-r}[/tex]

Upon substituting our given values in the above formula we will get,

[tex]S_8=\frac{3(1-(\frac{1}{2})^8)}{1-\frac{1}{2}}[/tex]

[tex]S_8=\frac{3(1-\frac{1^8}{2}^8)}{\frac{2-1}{2}}[/tex]

[tex]S_8=\frac{3(1-\frac{1}{256})}{\frac{1}{2}}[/tex]

[tex]S_8=\frac{3(\frac{256-1}{256})}{\frac{1}{2}}[/tex]

[tex]S_8=\frac{3(\frac{255}{256})}{\frac{1}{2}}[/tex]

[tex]S_8=3(\frac{255}{256}\times\frac{2}{1})[/tex]

[tex]S_8=3(\frac{255}{128})[/tex]

[tex]S_8=\frac{765}{128}[/tex]

Therefore, the sum of our given series is [tex]\frac{765}{128}[/tex].

store decreased its price on a computer by $112 to $478. What was the original price

Answers

Well if it's $112 less and the price is now $478. You just have to add $112 to $478= $590.

Answer:

$590.

Step-by-step explanation:

Let x be the original price of computer.

We have been given that a store decreased its price on a computer by $112 to $478.

This means x minus 112 equals to 478. We can represent this information in an equation as:

[tex]x-\$112=\$478[/tex]

Let us add $112 to both sides of our equation.

[tex]x-\$112+\$112=\$478+\$112[/tex]

[tex]x=\$590[/tex]

Therefore, the original price of computer was $590.

a company must select 4 candidates to interview from a list of 12, which consist of 8 men and 4 women.

How many selections of 4 candidates regardless of gender?
How many selections are possible, if 2 women must be selected?
How many selections are possible, if at least 2 women must be selected?

Answers

Part A

If 4 candidates were to be selected regardless of gender, that means that 4 candidates is to be selected from 12.

The number of possible selections of 4 candidates from 12 is given by

[tex] ^{12}C_4= \frac{12!}{4!(12-4)!}= \frac{12!}{4!\times8!} =11\times5\times9=495[/tex]

Therefore, the number of selections of 4 candidates regardless of gender is 495.

Part B:

If 4 candidates were to be selected such that 2 women must be selected, that means that 2 men candidates is to be selected from 8 and 2 women candidates is to be selected from 4.

The number of possible selections of 2 men candidates from 8 and 2 women candidates from 4 is given by

[tex] ^{8}C_2\times ^{4}C_2= \frac{8!}{2!(8-2)!}\times \frac{4!}{2!(4-2)!} \\ \\ = \frac{8!}{2!\times6!}\times\frac{4!}{2!\times2!} =4\times7\times2\times3=168[/tex]

Therefore, the number of selections of 4 candidates such that 2 women must be selected is 168.

Part 3:

If 4 candidates were to be selected such that at least 2 women must be selected, that means that 2 men candidates is to be selected from 8 and 2 women candidates is to be selected from 4 or 1 man candidates is to be selected from 8 and 3 women candidates is to be selected from 4 of no man candidates is to be selected from 8 and 4 women candidates is to be selected from 4.

The number of possible selections of 2 men candidates from 8 and 2 women candidates from 4 of 1 man candidates from 8 and 3 women candidates from 4 of no man candidates from 8 and 4 women candidates from 4 is given by

[tex] ^{8}C_2\times ^{4}C_2+ ^{8}C_1\times ^{4}C_3+ ^{8}C_0\times ^{4}C_4 \\ \\ = \frac{8!}{2!(8-2)!}\times \frac{4!}{2!(4-2)!}+\frac{8!}{1!(8-1)!}\times \frac{4!}{3!(4-3)!}+\frac{8!}{0!(8-0)!}\times \frac{4!}{4!(4-4)!} \\ \\ = \frac{8!}{2!\times6!}\times\frac{4!}{2!\times2!}+\frac{8!}{1!\times7!}\times\frac{4!}{3!\times1!}+\frac{8!}{0!\times8!}\times\frac{4!}{4!\times0!} \\ \\ =4\times7\times2\times3+8\times4+1\times1=168+32+1=201[/tex]

Therefore, the number of selections of 4 candidates such that at least 2 women must be selected is 201.

Selections of 4 candidates regardless of gender would result in 12c4, or 12!/(8!*4!) = 9*10*11*12 = 495 possibilities. Selections of 4 candidates where exactly two must be women would result in 8c2 (for the men) * 4c2 (for the women) = 8!/(6!*2!) * 4!/(2!*2!) = 28 * 6 = 168 possibilities. Selections of 4 candidates where AT LEAST two must be women would result in the above 168 (2 women) plus groups where there are exactly three women (8c1*4c3 = 8*(4!/(3!*1!) = 8*4 = 32) plus groups where there are exactly 4 women (1). So there are 168 + 32 + 1 = 201 possible selections of 4 from this group where at least 2 are women.

Which second-degree polynomial function has a leading coefficient of –1 and root 5 with multiplicity 2?

Answers

A second degree polynomial function has the general form:

[tex]\displaystyle{f(x)=ax^2+bx+c[/tex], where [tex]a\neq0[/tex].

The leading coefficient is a, so we have a=-1.

5 is a double root means that :

i) f(5)=0,
ii) the discriminant D is 0, where [tex]D=b^2-4ac[/tex].

Substituting x=5, we have

f(5)=a(5)^2+b(5)+c,

and since f(5)=0, and a is -1 we have:

0=-25+5b+c
thus c=25-5b.

By ii) [tex]\displaystyle{b^2-4ac=0[/tex].

Substituting a with -1 and c with 25-5b we have:

  [tex]\displaystyle{b^2-4ac=0[/tex]
  [tex]\displaystyle{b^2-4(-1)(25-5b)=0[/tex]
  [tex]\displaystyle{b^2+4(25-5b)=0[/tex]
  [tex]\displaystyle{b^2-20b+100=0[/tex]
  [tex]\displaystyle{(b-10)^2=0[/tex]
  [tex]\displaystyle{b=10[/tex]

Finally we find c: c=25-5b=25-50=-25

Thus the function is      [tex]\displaystyle{f(x)=-x^2+10x-25[/tex]

Remark: It is also possible to solve the problem by considering the form

[tex]f(x)=-1(x-5)^2[/tex] directly.
