The formula below can be used to model which scenario? a^1 = 3,000
a^n= 0.80 . a^n-1 n
A. The first row of a stadium has 3000 seats, and each row thereafter has 80 more seats than the row in front of it.
B. The last row of a stadium has 3000 seats, and each row before it has 80 fewer seats than the row behind it.
C. A bank account starts with a deposit of $3000, and each year it grows by 80%.
D. The initial value of a specialty toy is $3000, and its value each of the following years is 20% less.

m∠vru = 80°

m∠urw = 15°

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.

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.
