4 hours, 3 hours, Sid respitively

Step-by-step explanation:

Tom:

2/3 ÷ 1/6

2/3 x 6/1

12/3

4 hr for tom

Sid:

1/3 ÷ 1/9

1/3 x 9/1

9/3

3 hr for sid

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
