here is a question really troubling
me.
A cylindrical tube rolling down a
slope of inclination θ moves a
distance L in the time T. The
equation relating these quantities is
L(3+(a^2 /P))=QT^2 sin θ where a is
the internal radius of the tube and
P and Q are constants.What are
the units of P and Q?
Let n be a positive integer. Then x^2 + 1
is a factor of (x^4 + 3)^n − [(x^2 + 3)(x^2 − 1)]^n
for ...
(A) All n
(B) Odd n
(C) Even n
(D) n ≥ 3
(E) None of these options
