Answer:
dV/dt = 13,5 [Km³/h]
Step-by-step explanation:
The volume f the cube is:
V = x³ where x is a side of the cube, then tacking derivatives with respect to time on both sides of the equation
dV/dt = 3*x² dx/dt
dx/dt = 2 km/h
at the time when the side x = 1,5 Km
dV/dt = 3* (1,5)²*2 [km³/h]
dV/dt = 13,5 [Km³/h]
I believe its C. because you have to solve for x.
Answer:
Snowball Sampling
Step-by-step explanation:
Based on the specific scenario that is being described it can be said that the best type of sampling for you to use would be Snowball Sampling. This is a unique nonprobability sampling technique where subjects for the experiment at hand are recruited from the existing subjects list of acquaintances. Such as in this case it would target all the acquaintances of the Sting-Ray owners.
