A certain plant was 11 feet long on the day it was plantedthe length grows by a constant amount everyday(inc. the first day it was planted).
if this plant grew by 10% b/w the 4th day and 10 th day after it was planted ,how many feet per day does the plant grow
Choose the correct answer.
A) a) 2 B) b) 4.5 C) c) 0.196 D) d) 5.5 E) e) 3
If the plant is 11 feet tall when it is planted, it will be 11 + k feet tall at the end of the day (where k is the constant length it grows by every day).   Similarly, at the end of the 4th day the plant must be 11 + 4k feet tall and at the end of the 10th day it must be 11 + 10k feet tall.   Therefore 6k = 0.1 (11 + 4k)   =&gt; k = 0.196   Therefore the plant grows by 1 feet every day.   Option (c) 0.196)
