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
Evaluate the volume with the given measurements.
Answer: 376.8 m^3
Answer: 1/6 is not equal to 6/12 because 6/12 is 1/2 and 1/6 is less
Step-by-step explanation:
You need to expand the brackets eg.
(w-9)8 basically means 8 x (w-9) = 8w-72
