Answer:
(a)
(b)$3763.31
Step-by-step explanation:
When a Principal, P is invested at an annual rate r, for a period of k times over n years, the Amount, A(t) after n years is given by the model:

In this case:
r=1.8%
Since it is compounded bimonthly, k=2X12=24
Therefore:

For P=$2400, and n=25 years

The balance in the account after 25 years is $3763.31.
Answer: a = 0.91421
Step-by-step explanation:
Hi! I'm assuming this question is using degrees for sin and not radians, let me know if that's right!
The equation seems a bit weird, but
a is approximately 0.91421
if you go to wolframalpha site, you can plug in this equation to the website and receive an answer !
Two counter-clockwise or clockwise rotations of 90° should become 180°
If you add a counter-clockwise and clockwise rotation of 90° together they will cancel out to 0°
If you add full rotations of either in any amount it will always be 0°
