Which of the following represents a geometric sequence? i 1/4, 1/4, 1/4, 1/4 ii 1/4, 1/5, 1/6 iii 1/4, 1, -4, 1/6 iv 1/4, -4, 1/4, -4

option I is a geometric sequence

Step-by-step explanation:

I1/4, 1/4, 1/4, 1/4

II      1/4, 1/5, 1/6

III     1/4, 1, -4, 1/6

IV     1/4, -4, 1/4, -4

For any geometric sequence there should be a common ratio

To find common ratio we divide consecutive terms

lets check option I

I1/4, 1/4, 1/4, 1/4

When we divide 1/4 by 1/4 we will get 1

Same 1 for other two terms, so common ratio is 1

Hence first option is a geometric sequence

a maximum of 4 killer whales are allowed.

Step-by-step explanation:

Volume of main tank, V = 359188.76 cu. ft.

Maximum density, d = 0.000011142 units/cu. ft.

Maxium number of killer whales allowed

= V*d

= 4.002

So a maximum of 4 killer whales are allowed.
