This is on my homework also ..................... so it would be $66 because you would multiply 6 times 11
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

Answer:
i did this before the answer is c
Answer:
9 sides
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
To find the number of sides n divide the sum by 40°
n = 360° ÷ 40° = 9
