I'm pretty sure its A. 85 but don't hold it against me
Answer:
50.4 square miles
Step-by-step explanation:
it tells you the answer..
If the total bill comes to $110.05, we know that we are going to have to take 15% of this for his tip.
So we convert 15% to a decimal by dividing by 100:
Then we multiply this by the amount of the bill:
So if we round this to the nearest cent, we get $16.51.
Therefore, Alberto's tip will be about $16.51.
Answer:
f(-4) = 5
Step-by-step explanation:
Explanation of
_
| 5, x < -3
f(x) | 2x² - 4, -3 ≤ x ≤ 4
| 1 - 6x , x > 4
_
When the x in f(x) is less than -3 than f(x) = 5
When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4
When the x in f(x) is greater than 4 than f(x) = 1 - 6x
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Now that we know this lets look back at the question.
We want to find f(-4).
Looking at the piece wise function we see that f(-4) follow x < -3 as "x" or -4 is less than -3. When x is less than -3, f(x) = 5, hence f(-4) = 5
