Suppose that p is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. find the measure of the reference angle for 330°, and then find sin(330°) and cos(330°).

Reference angle will be 30°

sin(330°) will be equal to

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle

As the angle is 330°

So the reference angle will be

Now we have to find the value of

sin(330°)

And now

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
