P(t)=500(1+4t/(50+t^2 ))
P'(t) = 500 [(50+t^2).4 - 4t.2t]/(50+t^2)^2
by the quotient rule
500 (-4t^2 + 200)/(t^2 + 50)^2
Hence
P'(2) = 500 . (-16 + 200)/54^2 ~= 31.6
Answer:

Step-by-step explanation:


Divide both sides by 4:


Answer:
7/6
It's 7/6 because 6/6 make up a whole which is the 1 in 1 1/6
then there is that left over 1/6 to make it 7/6
It could be anything they are both variables.
