Answer: The average rate of change is 3640.
Explanation:
The given function is,

The value of f(x) at x=1.



The value of f(x) at x=2.



The average rate of change of a function from x₁ to x₂ is,




Therefore the average rate of change is 3640.
Answer:
40.5g of salt is left after evaporating all the water.
Step-by-step explanation:
Here, 9% of 450g means that out of 450 gram of solution, 9% is the salt.
So, we need to calculate 9% of 450
i.e. 9% * 450 = 0.09 * 450 = 40.5g
Hence, 40.5 grams of salt is in 450 grams of solution.
i.e. 40.5g of salt is obtained after evaporating all the water from the solution.
