Find the EXACT value of sec (-120 degrees)

Mathematics

Well sec(-120) = 1/cos(-120).

We know that cos(-120) = -1/2.

So, 1/(-1/2) = -2.

This means that sec(-120) = -2.

Sec is 1/cos so sec -120 is 1/cos -120 which is -2

I just graphed the table next to the graph of g and compared the two.

The y-intercept of f is (0,8) and the y-intercept of g is (0, -2).  So f is GREATER THAN the y-intercept of g.

Now to do the average rate of change, I see from the interval [-6,-3] that f is decreasing and for g it is increasing.  Thus f is LESS THAN the average rate of change of g.

Answer:

A

Step-by-step explanation:

account balance on compound interest = principal amount (1+rate/100)^time

here there are t years  so toat months are 12t and ad interest is after each 4 months so time is 12t/4 =3t

now total balance = 3545(1.045)^3t

here 3545 is principal amount , rate is( 1.045-1)×100 =4.5% per 4 months and 3t is time so clearly 3t or 3 is a growth factor hence option A
