9. During a certain period in the life of an earthworm, its length, L cm, is directly proportional to the square root of N, where N is the number of hours after its birth. One hour after an earthworm is born, its length is 2.5 cm. 0 Find an equation connecting L and N. (ii) Find the length of an earthworm 4 hours after its birth. (iii) How long will it take for an earthworm to grow to a length of 15 cm?

step-by-step explanation:

ever thing time 1 is a multiply by 1 it get  

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !

10+4√2 is the answer. i dont have the time to explain.
