Answer:
The radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
We are given the following in the question:
Instant radius,r = 2 cm
Instant length,l = 9cm
The radius of the cylinder decreases.
Volume of cylinder =
Since the volume of the cylinder does not changes, we can write:
Rate of change of volume:
Puttiung values, we get
Thus, the radius is decreatsing at a rate 0.78 cm per second.
Answer:
The practical domain of the function is the set of all integers from 1 to 5, inclusive.
Step-by-step explanation:
It is given the initial number of sheets of paper is 45.
A store has 5 reams of paper, and each ream contains 500 sheets of paper.
Let f(x) represent the number of sheets after purchasing x reams.
Domain is the set of input. In other words domain is the set of x-values.
Since number of reams can not be a negative or fraction value, therefore, the domain of the function is {1,2,3,4,5}.
Andre needs to buy more sheets, so number of reams of paper can not be 0.
Thus, the practical domain of the function is the set of all integers from 1 to 5, inclusive.
