A geologist in South America discovers a bird skeleton that contains 43% of its original amount of C-14. N = Noekt
No= initial amount of C-14 (at time t = 0)
N = amount of C-14 at timet
k = 0.0001
t = time, in years
Find the age of the bird skeleton to the nearest year.

a. -0.3 > -0.33

its a, i had the same answer, its from study island right

step-by-step explanation:

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
