Answer:
It will take 30 days to reach the top of the 30-foot deep pipe.
Step-by-step explanation:
Let's track Sam Snail's movement each day:
Day 1 -
0 + 3 - 2 = 1
Day 2 -
1 + 3 - 2 = 2
Day 3 -
2 + 3 - 2 = 3
Day 4 -
3 + 3 - 2 = 4
Day ...
We can see that the day always matches up with the height on the pipe. This means for the snail to have traveled 30 feet, he needs to have spent 30 days with a constant rate of movement.
Hope this helps!
Recall that for
,
You can separate the two expressions with
and
, which both approach 1, so that the limit is
.
Alternatively, using L'Hopital's rule,
Idk if i'm exactly right but i think it's 500.73
Answer:
x>-6
Step-by-step explanation:
The expression you need to solve for this is: 2x+15>3
For now pretend that the > is a = and solve as you normally would for x.
Subtract 15 from both sides
2x=-12
Divide by 2
x=-6
Put the > back in
x>-6
