What Is The Domain And The Range To This

Answers

Answer 1

Answer:

Look Down below :P

Step-by-step explanation:

If you were looking for if it even has a domain and range let's say if the point (15/4,7) should have read (15/4,17) then a plot of these points appears to show a hyperbola and the x and y (f(x)) axes look like Asymptotes. If the general function has the form f(x)=a/x, then there should be a consistent value for a which can be found be substituting the points in the equation. Take one point (17,15/4) and we get 15/4=a/17, from which a=255/4. f(x)=255     x/4. We have no negative values as examples so we cannot assume that the function is defined for negative values of x. f(x)=255 x/4 fits all the points except for (15/4,7), which is possibly mis-typed. The domain of the function is therefore all values of x>0 and the range of f(x) is f(x)>0, assuming continuity and extrapolation of the function.

If the point (15/4,7) is valid then f(x) as defined above is invalid or incomplete. f(x) may be a piece wise function where f(x)=7 if and only if x=15/4. For 0<x<15/4 and x>15/4, f(x)=255 x/4. These would be the domain for x. The range of f(x) is f(x)>0 and f(x)=7 only when x=15/4.

Answers

Answer:

=

7

i

Explanation:

A square root of a number  

n

is a number  

x

such that  

x

2

=

n

Note that if  

x

is a Real number then  

x

2

0

.

So any square root of  

49

is not a Real number.

In order to be able to take square roots of negative numbers, we need Complex numbers.

That's where the mysterious number  

i

comes into play. This is called the imaginary unit and has the property:

i

2

=

1

So  

i

is a square root of  

1

. Note that  

i

is also a square root of  

1

, since:

(

i

)

2

=

(

1

i

)

2

=

(

1

)

2

i

2

=

1

(

1

)

=

1

Then we find:

(

7

i

)

2

=

7

2

i

2

=

49

(

1

)

=

49

So  

7

i

is a square root of  

49

. Note that  

7

i

is also a square root of  

49

.

What do we mean by the square root of  

49

For positive values of  

n

, the square root is usually taken to mean the principal square root  

n

, which is the positive one.

For negative values of  

n

, the square roots are both multiples of  

i

, so neither positive nor negative, but we can define:

n

=

i

n

With this definition, the principal square root of  

49

is:

49

=

i

49

=

7

i

The question remains: Where does  

i

come from?

It is possible to define Complex numbers formally, as pairs of Real numbers with rules for arithmetic like this:

(

a

,

b

)

+

(

c

,

d

)

=

(

a

+

c

,

b

+

d

)

(

,

b

)

(

c

,

d

)

=

(

a

c

b

d

,

a

b

+

c

d

)

These rules for addition and multiplication work as expected with commutativity, distributivity, etc.

Then Real numbers are just Complex numbers of the form  

(

a

,

0

)

and we find:

(

0

,

1

)

(

0

,

1

)

=

(

1

,

0

)

That is  

(

0

1

is a square root of  

(

0

Then we can define  

i

=

(

0

and:

(

=

A bacteria can double every 4 hours. If you start with 22, how many will you have in 18 hours?

Answers

Answer:

ii cud givee uu an explanation for understandment for help if still don't understand im sowwyy thenn.

Step-by-step explanation:

It is given that the number of bacteria doubles every hour.

Therefore, the number of bacteria after every hour will form a G.P.

with first term (a=30) and common ratio (r=2)

∴a

3

=ar

2

=(30)(2)

2

=120

Therefore, the number of bacteria at the end of 2nd hour will be 480.

a

5

=ar

4

=(30)(2)

4

=480

and a

n+1

=ar

n

=(30)(2)

n

 

Thus the number of bacteria at the end of nth hour will be (30)(2)

n

Geometric sequence can model the considered situation. The number of bacteria in 18 hours for the considered situation will be 264

What is  a geometric sequence and how to find its nth terms?

There are three parameters which differentiate between which geometric sequence we're talking about.

The first parameter is the initial value of the sequence.The second parameter is the quantity by which we multiply previous term to get the next term.The third parameter is the length of the sequence. It can be finite or infinite.

Suppose the initial term of a geometric sequence is [tex]a[/tex] and the term by which we multiply the previous term to get the next term is [tex]d[/tex]  

Then the sequence would look like

[tex]a, ad, ad^2, ad^3, ad^4,...[/tex] (till the terms to which it is defined)

Thus, the nth term of such sequence would be

[tex]T_n = ad^{n-1}[/tex]

We can model the given situation with the geometric sequence since each previous count is being doubled(multiplied by 2) per 4 hours.

We're given initial number of bacteria = a = 22

Each new element will be denoting number of bacteria after 4 hours from previous count.

So, from 0 to 16 hours, there are four set of 4 hours. Thus, n = 4

Since number of bacteria are doubling, thus, d= 2

We get fourth term  = number of bacteria after 16 hours

[tex]T_n = a(d)^{n-1} = 22 \times (2)^3 = 176[/tex]

Now, in the last 2 hours, assuming that if x -> 2x in 4 hours(which is increment of x), then in 2 hours, only x/2 must be incremented.(assuming linear growth in each 4 hour group).

Thus, after 18 hours, 176 + 176/2 will be the number of bacteria.

Thus, Number of bacteria after 18 hour for the given case = 176 + 88 = 264

Casey burrows 3200 for a computer system at a rate of 4.25% per year. How much simple interest will he owe if he takes 4 months to repay the loan? Round to the nearest cent.

Answers

Answer:

$45.33

Step-by-step explanation:

First we find 4.25% of $3200 to find the interest in 1 year.

For simple interest, use this formula:

I = Prt

where

I = amount of interest

P = principal amount (the amount deposited or borrowed)

r = annual interest rate

t = number of years

We have

I = ?

P = $3200

r = 4.45% = 0.425

t = 1 year

I = ($3200)(0.0425)(1)

I = $136

The interest in 1 year is $136.

Now we convert 4 months to years

1 year = 12 months

4/12 = 1/3

4 months are only 1/3 of a year, so he pays only 1/3 of the interest of an entire year.

1/3 * $136 = $136/3 = $45.3333...
