Answer:

Step-by-step explanation:

For positive rate of change 

The given expression is

And since we have x+2 common in numerator and denominator, there is a hole at x+2=0, that is at x=-2
And a function is undefined when denominator is zero. And at x=-6, denominator become zero.
So, at x=-6, the function is undefined, or there is a vertical asymptote at x=-6 and hole at x=-2 .
Answer:
1800 liters
Step-by-step explanation:
150*150*80=1800000 cubic cm
1800000/1000= 1800 liters
Might seem like a lot but really isn't.
180-108= 172 172 divided by 5 is 14.4 z=14.4
180-67=113 y=113
