<span>Part A
</span>Chorus:
Expontential growth = b*a^x
b = 15
a = 1.12 (a= r+1), r = 12%
Which gives a function of f(x) = 15*1.12^x
Band
Linear growth = ax+b
a = 2
b = 30
Which gives a function of g(x)=2x+30
<span>Part B:
</span>f(9) = 15*1.12^9 = 41.59
g(9) = 2*9+30 = 48
<span>Part C:
</span>This is probably problem solving, where you're allowed to use calculators and other softwares.
Therefore you can use different softwares, and make f(x) = g(x).
I did this, and got it to 10.95427141

Answer:
Pool will be filled in 280 hours
Step-by-step explanation:
Inlet pipe fills in 40 hours = 1 pool
Inlet pipe fills in 1 hours = 
Drain pipe empty in 42 hours = 1 pool
Drain pipe empty in 1 hour = 
If both pipes are opened together
then in pool fills in 1 hour =
- 
on simplifying the right side ,we get 
= 
= 
pool fills in 1 hour
1 pool will be filled in 840 hours
pool is filled
empty pool = 1 -
= 
therfore
pool will be filled in
X 840 =
= 280 hours
