P = [60] cm
Explanation:
6.5 cm + 6.5 cm + 7.5 cm + 7.5 cm + 7.5 cm + 7.5 cm + 8.5 cm + 8.5 cm
The domain is easiest. You simply need to find the fractions, and exclude any X that makes the denominator zero. So in this case, your domain is everything except X=7.
For range, you are trying to find out what are the possible answers. Usually the best way to do this is to try x=infinity, and x=negative infinity, which here gives you answers of infinity and negative infinity. Since the function is almost continuous, I think your range is any real number.
For this case we have to by definition, if two lines are perpendicular then the product of its slopes is -1.
That is to say:
We have the following equation:
So:
Thus:
Thus, a line perpendicular to the given line must have slope
Option A:
It is not perpendicular!
Option B:
If it is perpendicular!
Option C:
It is not perpendicular!
Option D:
It is not perpendicular!
The correct option is option B
ANswer:
Option B
