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:
The distance from house to school = 4.2 * 0.75
= 3.15 miles
His balance will be $6 because -19 - 35 = -54, he added 60 to the -54 so that makes 6 or $6
They would be equal here!
So, 6x - 2 = 10x - 30
= 10x - 6x = 30 - 2
4x = 28
x = 28/4
x = 7
In short, Your Answer would be 7
Hope this helps!
