Answer:
f(1) = 81
Step-by-step explanation:
f(n + 1) = 1/3 f(n)
⇔ f(n) = 3 × f(n + 1)
……………………………
if f(3) = 9 ⇒ f(2) = 3 × f(3) = 3 × 9 = 27
Then
f(1) = 3 × f(2) = 3 × 27 = 81
Samuel is incorrect because he didn't subtract the power of the numbers.
<h3>How many more rod cells are there?</h3>
The number of rod and cone cells in the human eye is written in scientific notation. Scientific notation is used in expressing large numbers in smaller numbers. To write a number in scientific notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10. For example, 1 x 10² is equivalent to 100
(9.1 x 10^7) - (4.5 x 10^6)
= (9.1 - 4.5) x 10^(7 - 6)
4.6 x 10 = 46

(3x-10) (3x-10)
Both of the 10's have to be negative because -10 x -10 = 100
and if you use foil -30 + -30 = -60
2 5/6 = 17/6 = 2.833...to find the percent multiply the decimal by 100 and u get :
