Decide whether each of the following relations is a function. Explain your answer.
Input Outputs Functions?
(A) States Capitals
(B) States Cities
(C) Families Pets
(D) Families Last names

Answers

The functions are option (A) States Capitals and option (D) Families Last names

A function is a rule that determines the relationship between one variable and another. If we have a variable which we input into the relationship and gives a unique value for the other variable, the input value is the independent variable while the output is the dependent variable.

For an expression to be function, we must have a unique value of output for every value of input.

So, for option A, States have a unique capital, so it is a function.For option B, States have many cities, so the output is not unique, so it is not a function.For option C, Families can have many pets, so the output is not unique. So, it is not a function.For option D, Families can have only one last name, so the output is unique. So, it is a function.

So, the functions are option (A) States Capitals and option (D) Families Last names

Here is the algebraic solution:

T is the tens digit

O is the ones digit

T+O = 14

So O = 14 - T <---- this is the first equation

The original number is 10*T + O

If the digits are reversed the original number is increased by 18.

The number if the digits are reversed is:

10*O + T = 10*T + O + 18

10*(14-T) + T = 10*T + (14-T) + 18 <--- substitutes O with 14-T per first equation above in bold

140 - 10T + T = 10T + 14 - T + 18 <--- distributive left side

140 - 9T = 9T + 32

140 = 9T + 9T + 32

140 - 32 = 9T + 9T

108 = 18T

108/18 = T

T= 6

THe tens digit is 6.

The ones digit must be 8.

Reversing 86 - 68 = 18

The original number is 68.

If an arithmetic sequence has terms a5 = 20 and a9 = 32, what is a15?

Answers

Based on the information given, it can be deduced that the value of the 15th term is 50.

a + 8d = 32 ..... i

a + 4d = 20 ...... ii

Subtract ii from i

4d = 12

d = 12/4

d = 3

Therefore, a will be:

a + 4d = 20

a + 4(3) = 20

a + 12 = 20

a = 20 - 12 = 8

Therefore, the 15th term will be:

= a + 14d

= 8 + 14(3)

= 8 + 42

= 50

The 15th term is 50.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary).
6, 8, 32/3...
Find the 6th term.

Answers

Answer:

a₆ ≈ 25.284

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

8 ÷ 6 = [tex]\frac{32}{3}[/tex] ÷ 8 = [tex]\frac{4}{3}[/tex]

This indicates the sequence is geometric with nth term

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 6 and r = [tex]\frac{4}{3}[/tex] , then

a₆ = 6 × [tex](\frac{4}{3}) ^{5}[/tex] = 6 × [tex]\frac{1024}{243}[/tex] = [tex]\frac{6(1024)}{243}[/tex] ≈ 25.284 ( to the nearest thousandth )

Step-by-step explanation:

it is a geometric sequence.

the common ratio or factor is 4/3.

I got this by simply trying to get from the 2nd to the 3rd term.

8×x = 32/3

24x = 32

x = 32/24 = 16/12 = 8/6 = 4/3

s1 = 6

s2 = s1 × 4/3 = 6 × 4/3 = 24/3 = 8

s3 = s2 × 4/3 = s1 × 4/3 × 4/3 = 6 × 16/9 = 2 × 16/3 = 32/3

sn = s1 × (4/3)^(n-1)

s6 = 6 × (4/3)⁵ = 6 × 1024/243 = 2 × 1024/81 = 2048/81 =

the ans is 0.72, your answer is 479.20

Step-by-step explanation:

The solution to the given decimal division is calculated as: 479.17

How to divide decimal numbers?

To divide decimals, we need to convert both numbers to a simple unit and divide to get:

345.00/0.072

We know that 0.072 can be written as:

0.072 = 72 * 10⁻³

345.00 can be written as:

345.00 = 34500 * 10⁻²

Thus, we have:

(34500 * 10⁻²)/(72 * 10⁻³)

= (34500/72) * (10⁻²/10⁻³)

= 479.17 * 10

In the library, computers are on 68% of the desks. The library has 25 desks in total, 17 of which have computers.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

It is given that, in the library, 68% of the desks have computers. If 17 desks have computers.

Suppose the total number of desks is x.

68 % of x = 17

(68/100) × x = 17

x =(17×100) /68

x =25 desks

Thus, in the library, computers are on 68% of the desks. The library has 25 desks in total, 17 of which have computers.

Hi there!

When dividing fractions, we flop over the fraction that we divide by and multiply by it instead. Look what happens:

[tex]\frac{1}{4} :\frac{9}{1} =\frac{1}{4} *\frac{1}{9}[/tex]

Now we multiply the numerator by the numerator and the denominator times the denominator:

[tex]\frac{1}{36}[/tex]

Now we do the same thing with the following fractions:

[tex]\frac{9}{1} :\frac{1}{4} =\frac{9}{1} *\frac{4}{1} =36[/tex]

Therefore, our answers are: [tex]\frac{1}{36}[/tex] and 36.

hi hun!

From what I understand, ill explain to the best of my knowledge so u understand!

First. off they asked for "proportionality" basically asking for the rate it's growing at or weeks its taking.

I see that:

Flower 1: 6 inches

Flower 2: 10 inches

Flower 3: 14 inches

The proportionality which these flowers are growing at is 4 inches every two weeks.

And I also see:

Week 3

Week 5

Week 7

When u look closer u can see that the weeks are divisible by the inches for each of the flowers and each answer u get is 2!

And also just by looking at the weeks which are 2 weeks separate if u count them.

Week 3 would be:

6/3=2

Week 5 would be:

10/5=2

Week 7 would be:

14/7=2

so the proportionality is 2! c:
