Answer: 
Step-by-step explanation:
Given
Population of dust particle doubles every 30 minutes
If the initial sample is 21 grams
The model to predict the population will be

Where t=time in hours
A day has 24 hours . So, for 2 days time is 48 hours
Population is given by
Answer:
<em>a = 6 </em>
Step-by-step explanation:
g(x) = 5x - 2
h(x) = √(x + 3)
g(h(x)) = 5
- 2
g(h(a)) = 5
- 2
5
- 2 = 13
5
= 15
= 3
(
)² = 3²
a + 3 = 9
<em>a = 6</em>
