Answer:
-1/4
Step-by-step explanation:
We can find the slope of the line given two points
m = (y2-y1)/(x2-x1)
= (-9- -6)/(3- -9)
= (-9+6)/(3+9)
=-3/12
= -1/4
First half is negative and second is positive
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.
