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

Help, please (single variable calculus)
balandron [24]

Hi there!

\large\boxed{ 14.875}

Our interval is from 0 to 3, with 6 intervals. Thus:

3 ÷ 6 = 0.5, which is our width for each rectangle.

Since n = 6 and we are doing a right-riemann sum, the points we will be plugging in are:

0.5, 1, 1.5, 2, 2.5, 3

Evaluate:

(0.5 · f(0.5)) + (0.5 · f(1)) + (0.5 · f(1.5)) + (0.5 · f(2)) + (0.5 · f(2.5)) + (0.5 · f(3)) =

Simplify:

0.5( -2.75 + (-3) + (-.75) + 4 + 11.25 + 21) = 14.875
