Trig: Which complex number's graph is shown?

Andrei [34K]

ANSWER

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

EXPLANATION

The complex number shown has coordinates (2,-2)

$z = 2 - 2i$

The modulus is

$|z| = \sqrt{ {2}^{2} + {( - 2)}^{2} }$

$|z| = \sqrt{ 8} = 2 \sqrt{2}$

The argument is

$\theta= \tan^{ - 1} ( \frac{ - 2}{2} )$

$\theta= \tan^{ - 1} ( -1) = \frac{7\pi}{4}$

The polar form is

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

The first option is correct.

If there are tickets sold to children for $5 and $12 to adults, and there are only 400 tickets sold for $3925 then how many chil

Sever21 [200]

125 children tickets were sold

<u>Solution</u>:

Given that

Price of 1 ticket sold to children = $5

Price of 1 ticket sold to adult = $12

Total number of ticket sold = 400

Amount generated by selling 400 tickets = $3925.

Need to calculate number of ticket sold to children’s

Let’s assume number of tickets sold to childrens = x

So number of tickets sold to adults = 400 – x

Amount generated from x ticket sold to children $=x \times \text { Price of } 1 \text { ticket sold to children }$

$x \times 5=5 x$

Amount generated from (400 – x) tickets sold to adults $=x \times \text { Price of } 1 \text { ticket sold to adult }$

$=(400-x) \times 12=4800-12 \mathrm{x}$

<em>Total amount generated from 400 tickets = Amount generated from children’s tickets + Amount generated from adults ticket </em>

= 5x + (4800 – 12x) = 4800 -7x

As given that amount generated = 3965

=> 3965 = 4800 – 7x

Solving above expression to get value of x, we get

7x = 4800 - 3965

=> 7x = 875

=> x = 125.

Hence number of children tickets sold = 125.
