Answer:
3.5 miles
Step-by-step explanation:
The actual choices and question is as attached. Since it's shown in a mixed fraction as then we convert the number to decimal. \frac {1}{2} will be 1 divided by 2 which is 0.5 hence the distance to Cascade Falls is 3.5 miles
It takes 8.35 hours for the size of the sample to double
Step-by-step explanation:
The form of the continuous exponential growth model is
, where
∵ The growth rate is 8.3%
∴ r = 8.3 ÷ 100 = 0.083
∵ The size of the sample will doubled in t hours
∴ A = 2 P
Use the formula of the contentious exponential growth above
∵
- Divide both sides by P
∴
- Insert ㏑ in both sides
∴
- Remember because ㏑(e) = 1
∴
- Divide both sides by 0.083
∴
∴ t = 8.35 hours to the nearest hundredth
It takes 8.35 hours for the size of the sample to double
