Someone helped me solve this but then i saw the "t >= 1" so i dont think it works anymore... hear is the question: An oil tanker aground on a reef is losing oil and producing an oil slick that is radiating out at a rate approximated by the function dr/dt=20/sqrt(t), t >= 1, where r is the radius of the circular slick in metres after t minutes. If the radius of the slick is 21 metres, after 15 seconds, find, to the nearest metre, the radius of the slick after 10 minutes Hear is my awnser 1=40*sqrt(0.25)+c so c = 1 r=40*sqrt(t)+1 r=40*sqrt(10)+1=127.491 nerest meter is 127
