Answer:
The equation for the perpendicular bisector of the line segment will be:
Step-by-step explanation:
Given the endpoints of the line segments
Determining the slope between (5,-4) and (-9, -8)
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 2/7
Thus, the slope of the the new perpendicular line = – 1/m = (-1)/(2/7)= -7/2
Next, determining the mid-point between (5,-4) and (-9, -8)
Refine
We know that the point-slope form of equation of line is
where
- m is the slope of the line
substituting the slope of the perpendicular line -7/2 and the point (-2, -6)
Subtract 6 from both sides
Therefore, the equation for the perpendicular bisector of the line segment will be:
Answer:
12 tickets for $38.68 is the best deal.
Step-by-step explanation:
Since the top of the person's head is above the water (by 1.6 feet), that means the water is less than 5.8 feet (the person's height).
So we have to subtract 5.8 - 1.6, and I believe the answer will be 4.2 feet.
The pool is 4.2 feet deep :)
