Let f(x) =x+1/x

1. f(1)
2. (f •f)(1)
3. (f•f•f)(1)
4. (f•f•f•f)(1)
5. (f•f•f•f•f)(1)​

Answers

Answer 1

Problem 1

f(x) = x + 1/x

f(1) = 1 + 1/1

f(1) = 1 + 1

f(1) = 2

Answer: 2

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

Problem 2

(f o f)(1) = f( f(1) )

(f o f)(1) = f( 2 )

(f o f)(1) = 2 + 1/2

(f o f)(1) = 4/2 + 1/2

(f o f)(1) = 5/2

Answer:  5/2

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

Problem 3

(f o f o f)(1) = f(  f(f(1)) )

(f o f o f)(1) = f(  (f o f)(1) )

(f o f o f)(1) = f(  5/2 )

(f o f o f)(1) = 5/2 + 1/(5/2)

(f o f o f)(1) = 5/2 + 2/5

(f o f o f)(1) = 25/10 + 4/10

(f o f o f)(1) = 29/10

Answer: 29/10

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

Problem 4

(f o f o f o f)(1) = f(   f(f(f(1))   )

(f o f o f o f)(1) = f(   (f o f o f)(1)    )

(f o f o f o f)(1) = f(   29/10   )

(f o f o f o f)(1) = 29/10 + 1/(29/10)

(f o f o f o f)(1) = 29/10 + 10/29

(f o f o f o f)(1) = 841/290 + 100/290

(f o f o f o f)(1) = 941/290

Answer: 941/290

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

Problem 5

(f o f o f o f o f)(1) = f(   f(f(f(f(1))))   )

(f o f o f o f o f)(1) = f(   (f o f o f o f)(1)  )

(f o f o f o f o f)(1) = f(   941/290  )

(f o f o f o f o f)(1) = 941/290 + 1/(941/290)

(f o f o f o f o f)(1) = 941/290 + 290/941

(f o f o f o f o f)(1) = 885481/272890 + 84100/272890

(f o f o f o f o f)(1) = 969581/272890

Answer: 969581/272890

Answer 2

A function assigns the values. The value of (f•f•f•f•f)(1)​ is 969581/272890.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

1.)

The value of f(1) for the given function f(x) =x+1/x can be calculated as shown below,

f(x) = x + 1/x

f(1) = 1 + 1/1

    = 1 + 1

    = 2

2.)

(f · f)(1) = f( f(1) )

Since the value of f(1)=2, therefore, it can be rewritten as,

(f · f)(1) = f(2)

           = 2 + 1/2

           = 4/2 + 1/2

           = 5/2

3.)

(f · f · f)(1) = f(  f(f(1)) )

Since the value of f(f(1))=5/2, therefore, it can be rewritten as,

(f · f · f)(1) = f(  (f·f)(1) )

              = f(  5/2 )

              = 5/2 + 1/(5/2)

              = 5/2 + 2/5

              = 25/10 + 4/10

              = 29/10

4.)

(f · f · f · f)(1) = f(  f(f(f(1))  )

Since the value of f(f(f(1)))=29/10, therefore, it can be rewritten as,

(f · f · f · f)(1) = f(   (f·f·f)(1)    )

                  = f( 29/10 )

                  = 29/10 + 1/(29/10)

                  = 29/10 + 10/29

                  = 841/290 + 100/290

                  = 941/290

5.)

(f · f · f · f · f)(1) = f(   f(f(f(f(1))))   )

Since the value of f(f(f(1)))=29/10, therefore, it can be rewritten as,

(f o f o f o f o f)(1) = f(   (f·f·f·f)(1)  )

                           = f(  941/290 )

                           = 941/290 + 1/(941/290)

                           = 941/290 + 290/941

                           = 885481/272890 + 84100/272890

                           = 969581/272890

Hence, the value of (f•f•f•f•f)(1)​ is 969581/272890.

Let f be a function such that f(2) ≤ f(x) for all values of x in the interval (0, 3). Does f(2) represent a relative minimum or a relative maximum?

Answers

Answer: f(2) is a relative minimum

This is because f(2) is the lowest y output for any given y = f(x) output on the interval [tex]0 < x < 3[/tex] which is what the interval notation (0,3) indicates.

Draw out a "parabolic" like shape where the lowest point occurs at (2, f(2)), where f(2) is unknown, but we at least know that x = 2. I put "parabolic" in quotes because it may not be a true parabola, but it looks like one. This lowest point only applies for the neighbor hood [tex]0 < x < 3[/tex].

Before multiplying fractions change any mixed numbers to

D improper fractions my brain said so

9514 1404 393

Answer:

  [D] improper fractions

Step-by-step explanation:

The usual recommendation for doing much of anything with mixed numbers is to change them to improper fractions.

__

However, that isn't always necessary. If you're doing the arithmetic with a calculator, it can be helpful to convert them to decimal numbers.* Sometimes, you can work with mixed numbers by working with the integer and fractional parts separately.

Sometimes a simple rewrite makes working with mixed numbers easier. (That is, converting part of the integer portion to a fraction may be useful in some cases.

Example:

  (29 1/3) × (1/2) = (28 4/3) × (1/2) = 14 2/3

_____

* Some calculators will do arithmetic directly with mixed numbers and/or fractions. If yours doesn't, it can be helpful to memorize the decimal equivalents of a few common fractions: 1/3, 2/3, 1/6, 1/7, 1/9, 1/11 for example. This will help you convert the decimal result back to a mixed number.

Create a simulation that would represent this situation and complete 10
trials. Show all of your work for full credit.

Answers

If you have 10 choices. You have about a 50 50 of passing or failing. Your chances would be 5/10 Wich would simplify to 1/2

Based on the binomial probability principle, the probability of passing the quiz if all answers are guessed [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]

Let :

Number of questions passed = kNumber of trials, n = 10Probability of success, p = 1/2 = 0.50q = 1 - p = 1 - 0.50 = 0.50

Using the binomial probability relation :

[tex] P(x = x) = nCx \times p^{x} \times q^{n-x} [/tex]

x = k

Substituting the values into the relation :

[tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]

Hence, the required probability expression is [tex] P(x = k) = 10Ck \times 0.50^{k} \times 0.50^{10-k} [/tex]
