THE AVERAGE WEIGHT W (IN POUNDS) OF AN ATLANTIC COD AGED t YEARS CAN BE MODELED BY THE EGUATION W=1.16(1.44)^t.

FIND THE RATIO OF THE WEIGHT OF A 5 YEAR OLD COD TO THE WEIGHT OF A 2 YEAR OLD COD. EXPRESS THIS RATIO AS A POWER OF 1.44!!!!!!

HOW WOULD I DO THIS???

• PRE ALGEBRA -

weight of a 5 year old cod = 1.16(1.44)^5
weight of a 2 year old cod = 1.16(1.44)^2

so when we form the ratio (1.16(1.44)^5):(1.16(1.44)^2) it reduces to
(1.44^3):1
