Is "8.313313331..." a rational or irrational number

Mathematics

Answer:

Irrational

Step-by-step explanation:

Repeating decimals are rational.  Nonrepeating are irrational.

This is a nonrepeating decimal.  First you have one 3, then two 3s, then three 3s.  It's not a repeating pattern.  So it's an irrational number.

Which graph represents the function f(x)=−4x−3?
Evgen [1.6K]
<h2>Answer:</h2>

The graph on the top left.

<h2>Step-by-step explanation:</h2>

f(x) = -4^x - 3

That means that when x = 0...

f(0) = -4^0 - 3

f(0) = -1 - 3

f(0) = -4

So, the function will have a point at (0, -4). We can eliminate the two graphs on the right.

When x = 1...

f(1) = -4^1 - 3

f(1) = -4 - 3

f(1) = -7

So, the function will have a point at (1, -7). That corresponds to the graph on the top left.

Alright I have a question for all of you! You put $550 in an account that earns 4.4% simple interest per year. How much interest
svetlana [45]
First, converting R percent to r a decimal
r = R/100 = 4.4%/100 = 0.044 per year,
putting time into years for simplicity,
6 months ÷ 12 months/year = 0.5 years,
then, solving our equation

A = 550(1 + (0.044 × 0.5)) = 562.1
A = $ 562.10

The total amount accrued, principal plus interest,
from simple interest on a principal of $ 550.00
at a rate of 4.4% per year
for 0.5 years (6 months) is $ 562.10.

Find​ f(x) and​ g(x) such that ​h(x)equals​(fcircle​g)(x). h left parenthesis x right parenthesis equals left parenthesis 2 x pl
GaryK [48]

Answer:

  • f(x) = x^3
  • g(x) = (2x+4)^2

Step-by-step explanation:

There are many ways to decompose h(x) into f(x) and g(x). The main purpose of the exercise seems to be to get you to think about the operations that are performed on x, then divide that list of operations into two parts.

In the function ...

  h(x) = (2x +4)^6

the variable x is ...

  • multiplied by 2
  • 4 is added to the sum
  • the sum is raised to the 6th power

Of course, the 6th power can be considered as the cube of a square or the square of a cube, if you like.

In the decomposition shown in the answer above, we have chosen to put most of this list in g(x), including the square of the sum. Then we have made f(x) be the cube of that square.

  h(x) = f(g(x)) = (2x+4)^6

When f(x) = x^3, this is ...

  h(x) = f(g(x)) = g(x)^3 = ((2x+4)^2)^3

so ...

  g(x) = (2x+4)^2 . . . and . . . f(x) = x^3

_____

Other possible decompositions are ...

  • g(x) = 2x
  • f(x) = (x+4)^6

or

  • g(x) = (x+2)
  • f(x) = (2x)^6

or

  • g(x) = 2x+4
  • f(x) = x^6

or ... (many others)

A cable 84 meters long is cut into two pieces so that one piece is 18 meters longer than the other. Find the length of each piec
lesantik [10]

Answer:

half of 84 is 42. Since the total difference is 18 meters you will increase one by 9m and decrease the other by 9m....therefore 42-9=33. 42+9=51
