Okay so what f(3) is saying is that x=3. You have to plug three in for x to make the new equation of 2(3)^3-3(3)+1 next you would do pemdas which is parethesis then exponets then multiplication/division then addition/subtraction to get 2*3=6 6^3 is 216 216-3*3 is 207 207+1 is 208 so the answer is f(3)=208
Answer:
The water level will change at a rate of - 2 7/18 inches per year
Step-by-step explanation:
From the question, we have a change of -7 1/6 inch every 3 years
We now want to calculate the value of the change every year
Mathematically, that will be;
- 7 1/6 divided by 3
= -43/6 divided by 3
= -43/18 = - 2 7/18 inch per year
3/4 an hour equals 45 minutes.
45 * 6 = 270 minutes over 6 days
1 hours = 60 minutes
270 / 60 = 4.50 hours
