Answer:
176 ÷ 22 = 8 132 ÷ 22 = 6
Last week, Kimberly read for 8 hours, and this week she read for 6 hours. So in total she read for 14 hours.
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
- A is the new value
- P is the initial value
- r is the rate of growth or decay in decimal
- t is the time
∵ 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
