The answer is A. Just remember the acronym for foil.
Answer:
-1 < x < 3
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:
yes
Step-by-step explanation:
They both equal to one half, which makes them proportional
