Answer:
choose x ≥ 0 or x ≤ 0
Step-by-step explanation:
The vertex of the parabola is at x=0. If values of x are included from both sides of the vertex, the function will not pass the horizontal line test. So, the domain must be limited so that it does not include both positive and negative values of x.
The domain could be x ≥ 0, or x ≤ 0, or some subset of either of these intervals.
Okay so the formula for speed is speed = distance divided by time so 120 /4 is 30 for the first bar
Answer:
187.5 gallons
Step-by-step explanation:
Make a proportion
= 
3000/16 = 187.5, so multiply 1 by 187.5 to find the gallons used in a year
This gets you 187.5 gallons used in a year
simplifying
we get 
Step-by-step explanation:
We need to simplify: 
Solving:
Applying the rule:
log a + log b = log(ab)

So, simplifying
we get
