Plz answer asap ! i would really appreciate it!

0.5

2

4π

Step-by-step explanation:

One cycle resets the process. For this to happen, it must go up, then down to where it started, down more, and then up to where it started. This only goes halfway there, so our first answer is 0.5

The amplitude is the difference in height between the base and the top/bottom, and this is 2.

The period is how long it takes to complete one cycle -- it's halfway at 2π, so it would be fully there at 4π

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
