To compute for the Derricks new balance:
New balance= previous balance + interest of previous balance-payment +new transaction
where
previous balance = 3264.75
interest of previous balance = 3264.75x(APR/12)=35.91225
APR=13.2%/12, 1.1%
payment= 180
new transaction= 134
new balance = 3254.66225
Derricks new balance in his account is 3254.66225.
You simplify
4i(2-i)(5+31)
And you get
144+288i
(C) sin(-r) = -a
(D) sin(r) = -a
<u>Explanation:</u>
The unit circle definition allows us to extend the domain of sine and cosine to all real numbers. The process for determining the sine/cosine of any angle θ is as follows:
Starting from (1,0) move along the unit circle in the counterclockwise direction until the angle that is formed between your position, the origin, and the positive x-axis is equal to θ.
- sin θ is equal to the y-coordinate of your point, and
- cosθ is equal to the xxx-coordinate.
In the question, sin(-r) = -a and sin(r) = -a is equal to the x-coordinate, thus they are not correct.
