Answer:
A-a fair cube
Step-by-step explanation:
Answer: a) Explicit formula :
b) Recursive formula :
and 
Step-by-step explanation:
Since we have given that
Number of grams of yeast in a culture dish initially = 9 grams
According to question, a certain culture of year increases by 50 % every three hours.
So, the explicit formula will be

And the recursive formula will be

Hence, a) Explicit formula : 
b) Recursive formula :
and 
Answer:
Step-by-step explanation:
- Initial number = 10
- Weekly growth rate = 15% or 1.15 times
<u>Equation for this relationship:</u>
- V(t) = 10*1.15^t, where t - number of weeks
<u>Number of views in 5 weeks:</u>
- V(5) = 10*1.15^5 = 20 views (rounded)
