Answer: Use the given functions to set up and simplify (f - g)(x). You should get 3x^2 +4x+2
John exercised 20% more than Toby. So the number of hours that John exercises per week is 14 + 0.2(14) = 14 + 2.8 = 16.8.
Jenny exercises two more hours than John. So the number of hours that Jenny exercises per week is 16.8 + 2 = 18.8.
So an expression representing the number of hours that Jenny exercises after w weeks is 18.8w.
Answer:
a) 15 000 litres
b) 1/3
Step-by-step explanation:
a) Since the pool has 7500 litres when half full, it must have double that when full.
7500 * 2 = 15 000
b) Since the full pool is 15000, when the pool has 5000 litres it has 5000 out of 15000, hence the fraction 5000/15000 which simplifies to 1/3.
Simplification: divide the numerator and denominator by 5000.
