Answer:
they can stay in there for 8 hours which in all would be $93.20
Step-by-step explanation:
To solve the question we proceed as follows:
length=width=x ; g=height=h
thus
V=x*x*h
v=x^2h
dv/dt=2xh dx/dt+x^2 dh/dt
but
dx/dt=2 ft/sec
dh/dt=-2 ft/sec
thus plugging the values in the equation we get:
dv/dt=2×10×12+10²(-2)
dv/dt=240-200
dv/dt=40 ft³/sec
Answer:
10.
Step-by-step explanation:
If you mean the number of combinations of 2 from 5 it is
5*4 / 2*1
= 10.
