Answer:

Nina is not correct because 393.5$ less then yesterday's ticket sales.

Step-by-step explanation:

To find total sales she he is not correct because

3 / 4 of 1440 = 1,080$ ticket sales from yesterday

and 295.25 - 33.50 = 261.75$

Therefore, ( 3 / 4 * 1440 ) + ( 295.25 - 33.50 ) = 1,341.75$ sale of today

Ticket from yesterday and today

1,080 - 1,341.75 = 393.5

393.5$ less then yesterday's ticket.

Given:

$|3+4 i|+|3-4 i|+|-3+4 i|+|-3-4 i|$

Solution:

Complex formula:

$|a+b i|=\sqrt{(a+b i)(a-b i)}=\sqrt{a^{2}+b^{2}}$

Let us simplify one by one.

$|3+4 i|=\sqrt{3^{2}+4^{2}}$

$=\sqrt{25}$

|3 + 4i| = 5

$|3-4 i|=\sqrt{3^{2}+(-4)^{2}}$

$=\sqrt{25}$

|3 - 4i| = 5

$|-3+4 i|=\sqrt{(-3)^{2}+4^{2}}$

$=\sqrt{25}$

|-3 + 4i| = 5

$|-3-4 i|=\sqrt{(-3)^{2}+(-4)^{2}}$

$=\sqrt{25}$

|-3 - 4i| = 5

Substitute these in the given expression:

$|3+4 i|+|3-4 i|+|-3+4 i|+|-3-4 i|=5+5+5+5$

$=20$

The solution of the expression is 20.
