Which statement does not describe the sine function?

Mathematics

liberstina [14]2 years ago

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.

I would say A. It’s reciprocal function is cosecant.

Joseph earns $15 for every lawn he mows. Is the amount of money he earns proportional to the number of lawns he mows? Make a tab
Vedmedyk [2.9K]

Given that Joseph earns $15 for every lawn he mows.

so if he mows lown 1 time then his earning = $15

if he mows lown 2 time then his earning = $15*2= $30

if he mows lown 3 time then his earning = $15*3= $45

if he mows lown 4 time then his earning = $15*4= $60

if he mows lown 5 time then his earning = $15*5= $75


So the required table will be:


From the table we can see that Joseph's earning increases by $15 each time so we can say that YES, the amount of money he earns proportional to the number of lawns he mows.

Which of the following statements best describes the location of −(−5) on a number line?
Korolek [52]
Hello,

-(-5) is also known as just a plain positive 5. When two negatives are multiplied together, they make the number positive. So, the location of -(-5) on a number line would be on the number 5. I hope this helps!
