Final answer:
The yearly growth factor can be found using the formula: Yearly Growth Factor = (Decade Growth Factor)^(1/10). Plugging in the given value of 2.6, the yearly growth factor is approximately 1.1304.
Step-by-step explanation:
To find the yearly growth factor, you need to find the factor by which the quantity grows each year. In this case, the decade growth factor is 2.6, which means the quantity grows by 2.6 times every 10 years. To find the yearly growth factor, you can use the formula:
Yearly Growth Factor = (Decade Growth Factor)^(1/10)
Plugging in the given value, the yearly growth factor is:
Yearly Growth Factor = 2.6^(1/10)
Calculating this, the yearly growth factor is approximately 1.1304.
