100分求一道数学题,After t years the population of a certain town is P(t) = 50+5t thousand people.A populationP has an associated CO2 level,C(P) = (根号下（P2 + 1）)/2.After 2 years,the rate at which CO2 level is changing with respect to t
100分求一道数学题,
After t years the population of a certain town is P(t) = 50+5t thousand people.A populationP has an associated CO2 level,C(P) = (根号下（P2 + 1）)/2.After 2 years,the rate at which CO2 level is changing with respect to t will be:答案是150/根号下3601 实在闹不明白为什么,
C(P) = (根号下（P2 + 1）)/2.P后面的2表示P的平方

100分求一道数学题,After t years the population of a certain town is P(t) = 50+5t thousand people.A populationP has an associated CO2 level,C(P) = (根号下（P2 + 1）)/2.After 2 years,the rate at which CO2 level is changing with respect to t
P（t）=50+5t
C（p）=(根号下（P2 + 1）)/2.
求的是变化率
C（p）=[根号下（50+5t）²+1]/2=[根号下（2501+500t+25t²）]/2
dC/dt=(500+50t)/｛4[根号下（2501+500t+25t²）]｝
当t=2的时候
dC/dt=（500+100）/[4根号下（3601）]
=600/[4根号下（3601）]
=150/[根号下（3601）]

题目的意思是：T年之后某个小镇的人数是P（t）=50+5t（千人）。人数p和CO2的含量有关，具体关系是C（p）=(根号下（P2 + 1）)/2.
2年后CO2将会是多少？还有你的答案是多少啊，，你打的是这个答案吗?150/根号下3601恩，求解你的答案是150/根号下3601 360后面有1吗？算了，不会了。。。有，你看题目就知道了，根号下P^2+1 前面公式求出进去就是...
