At the beginning of spring, Samantha planted a small sunflower in her backyard. When it was first planted, the sunflower was 20 inches tall. The sunflower then began
to grow at a rate of 1 inch per week. How tall would the sunflower be after 4 weeks?
How tall would the sunflower be after w weeks?
Height after 4 weeks:
Height after w weeks:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

i think its 7.6

if so your welcome

can you post a picture or something
