Which statement does not describe the sine function?

Mathematics
2 answers:
liberstina [14]3 years ago
7 0

Answer:

Step-by-step explanation:

A is correct.  csc x = 1/ sin x

B is correct. y = sin x is a continuous funtion, for all real numbers, x

C is correct. The function y = sin x is a periodic function, and the cycle repeats every 2 radians (or 360°).

D is incorrect. It doesn't actually say anything false, but it does not accurately describe the behavior of the sine function. Look at the graphic I have attached. If you start at the origin, you see y = 0, then increases to 1 when x = π/2, <u>then decreases back to zero when x = π,</u> then decreases even more to -1 when x = 3π/2, then increases back up to zero when x = 2π.

Answer D leaves out the underlined part.

Hope this helps.

1,000.00 at 4.5% interest for 2 years
siniylev [52]
Each year we add 4.5% interest.
4.5% as a decimal is 0.045.
We multiply by 1.045 to add this interest.
(not 0.045, this would just be the interest and wouldn't keep the whole)

To start: $1,000
Multiply by 1.045 for the first year.
Now we have $1,045.
Multiply by 1.045 again for the second year.
Now we're at 1092.025.
We need to round up to the nearest cent...$1,092.03
