Perform the indicated operation & simplify. Express the answer as a complex number. ( 6 − 7 i ) ( − 8 + 3 i ) =___

slega [8]

( 6 − 7 i ) ( − 8 + 3 i )

First FOIL:

( 6 − 7 i ) ( − 8 + 3 i ) = -48 + 18i + 56i -21i^2

Combine like terms

= -48 + 74i -21i^2

Convert i^2 = -1

= -48 + 74i -21(-1)

And simplify

= -48 + 74i + 21

= -27 + 74i

Use a calculator to find a decimal approximation for the following trigonometric function.

forsale [732]

Converting
<span>43°24' intodegrees, we get
</span>
43°24' = 43° + 24'/60 = 43.4°

putting <span> sin(43.4)</span>into calculator to 8 decimal places

sin(43°24') = sin(43.4) = 0.68708751

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than a certain number of inches

Georgia [21]

So the “certain number” will be S.
Since 2width + 2length, the first part would be 2 times 2 which is 4
The length is S - 3
We then have to multiply this by 2
So it is 2(S-3) which is 2S-6
So the answer is 4+2S-6 which is 2S-2
