Acertain culture of yeast increases by 50% every three hours. a scientist places 9 grams of the yeast in a culture dish. write the explicit and recursive formulas for the geometric sequence formed by the growth of the yeast

Explicit:  

Recursive:  

Step-by-step explanation:

A certain culture of yeast increases by 50% every three hours

⇒ rate (r) is  

A scientist places 9 grams of the yeast in a culture dish.

⇒ first term of the sequence (a₁) = 9

The explicit rule for a geometric sequence is:

⇒

The recursive rule for a geometric sequence is:

⇒

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
