Answer:
Step-by-step explanation:
To find the values of the angle which makes maximum r you use the derivative of r
If you equals this derivative to zero you obtain the value of the angle:
However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.
hence, the answer is:
answer b
When solving this inequality, you would do the inverse to the other side.
Subtraction is the inverse of addition.
So,
n + 9 (-9) <-3 (-9)
n<-12
When you subtract two negative numbers, you continue to the left of the number line.
I hope this helps!

If the radiation level is 100%, it would take 2.4 days to take the radiation level to 50%. However, the situation implies that the radiation level is 25% only, so we need to take 25% from 2.4 days to know the timeframe for a room to be emptied from the radioactive gas. 2.4 days multiplied by 0.25 will give a result of 0.6 day - the timeframe needed to empty the room out of the radioactive gas.
