Answer:
I'd say A because this question is just like y and xays.
Step-by-step explanation:
Answer:
The first derivative of
(r(t)=5*t^{-2}) with respect to t is
(r'(t) = -10*t^{-3}).
Step-by-step explanation:
Let be
, which can be rewritten as
. The rule of differentiation for a potential function multiplied by a constant is:
, 
Then,

(r'(t) = -10*t^{-3})
The first derivative of
(r(t)=5*t^{-2}) with respect to t is
(r'(t) = -10*t^{-3}).
