Jillian planted a sunflower. the height of her plant can be expressed by the following function where d represents the number of days the plant has been growing and h(d) represents the height in inches.

h(d)= 3/7d + 5
how tall will her sunflower be after one week?

8in

Step-by-step explanation:

input (D) which is 7 days to find the height

h(d) = 3/7d +5

h = 3/7(7) + 5

h = 3+5

h=8

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
