Answer:

The rewritten statements is as follows:

(a) ∀ dinosaur x, x is extinct.

(b) ∀ real number x, x is positive, negative, or zero.

(c) ∀ irrational number x, x is not an integer.

(d) ∀ logician x, x is not lazy.

(e) ∀ integer x, x^2 \ne 2,147,581,953

(f)  ∀ real number x, x^2 \ne -1

Step-by-step explanation:

As a general rule, words like "all", "every", "the", etc. are represented with ∀.

However, some sentences may be need to rephrased before such sentence can be rephrased

So, the following replacement will be made:

(a)

All \to ∀

dinosaurs \to x

(b)

Every \to ∀

real\ number \to x

(c)

First, we need to rephrase this sentence to:

<em>Every irrational number is not integer</em>

<em />

So, the replacement is:

Every \to ∀

irrational\ number \to x

(d)

First, we need to rephrase this sentence to:

<em>Every logician is lazy</em>

<em />

So, the replacement is:

Every \to ∀

lazy \to x

(e)

First, we need to rephrase this sentence to:

The integer 2,147,581,953...............

So, the replacement is:

The \to ∀

Integer \to x

(f)  

Replace:

The \to ∀

-1 \to x^2

uysha [10]

Answer:The simplified expression that represents the uncle's age is

4y + 12

Let y represent your age.

Your sister is 3 years older than you. This means that your sister's age is y + 3

Your uncle is 4 times older than your sister. It means that the age of your uncle would be

4(y + 3)

The simplified expression that represents your uncle's age would be

4y + 12

How do you find the first five terms of a sequence defined recursively
Blizzard [7]
Interesting question. Good to know for computer science.
Suppose you have a function like 
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1

a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3

an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3 
a3 = 7

a4 = a3 + 3
a4 = 7 + 3
a4 = 10

a5 = a4+ 3
a5 = 10 + 3
a5 = 13

I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16

a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.

So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.
