which expression represents purely real numbers and which expression represents non-real complex number?​
Lyrx [107]

Answer:

Step-by-step explanation:

Complex numbers are the numbers represented by the expression = a + bi

Here a = real part of the number

bi = imaginary part

a and b are the real numbers.

i^9=(i^2)^4.(i)

    =(-1)^{4}.i [Since, i^2=-1]

    =i

Therefore, its a non real complex number.

2 - \sqrt{-49} = 2-\sqrt{(-1)(7)^2}

               = 2-7\sqrt{-1}

               = 2-7i

This number is a Non real complex number.

\sqrt{(-18)^2}=18\sqrt{-1}

              = 18i

It's a non real complex number.

3 + 2i

It's a non real complex number.

-289

It's a purely real number.

4-32i^2=4-32(-1)

             = 4 + 32

             = 36

It's a purely real number.

The campus bookstore knows from the past several semesters that a certain elementary statistics book has a demand that is approx
Likurg_2 [28]

Answer:

$117

Step-by-step explanation:

Given that:

They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each

Marginal Profit = Marginal Revenue – Marginal Cost.

Marginal Profit = $222 - $105

Marginal Profit = $117

the marginal profit for a single elementary statistics book $117

For the remaining unsold books in the middle of the semester he bundles them up and sells to vendor in another country for $40 each for which he suffers a marginal loss of $105 - $40 = $65 each
