ya C=21.8

Answer 10

Oh that makes sense!! Could you answer another one of my math problems?

Answer 11

Write the complex number in the form a + bi.

4[cos (-135°) + i sin (-135°)]

Answer 12

ok i will take a look

Answer 13

whats the value of cos (-135° ?

Answer 14

-2sqrt(2) - 2sqrt(2)i This is what I got

Answer 15

is that right? @priyar

Answer 16

thats correct.

Answer 17

here r=4

Answer 18

I was confused if it had to be a minus or plus

Answer 19

@hartnn

Answer 20

cos -135 and sin -135 are both -(sqrt 2)/2

so negative is correct.

Answer 21

Just one last one?
Given that P = (7, 16) and Q = (-1, 7), find the component form and magnitude of QP

Answer 22

<8, 9>, sqrt(145 is this right? @hartnn

Answer 23

QP = 8,9 , mag = sqrt 145
yes! \(\huge \checkmark \)

Answer 24
