Ninety tickets were sold by our school for the band fest. a tickets were sold for $3.00 each and b tickets were sold for $4.00 e

Lesechka [4]

Answer: 60= $3.00 and 30= $4.00

x=# of $3 tickets

90-x=# of $4 tickets

$3x+$4(90-x)=$300

3x+360-4x=300

-x+360=300

-x=-360+300

-x=-60

x=60 $3 tickets

90-60=30 $4 tickets

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.
