The equation of the perpendicular bisector.
First, calculate the midpoint of the given endpoints
Open bracket
Next, determine the slope of the given endpoints.
Next, calculate the slope of the perpendicular bisector.
When two lines are perpendicular, the relationship between them is:
In this case:
So:
Since the slope is 
, the equation is:
Where:
Recall that:
So:
Hence, the equation is:
Wrong person I pay someone to do my math for me :)
Well first you need to show the rest of the problems before i can truely help you sorry.
Answer:
1 3/5 miles/hr
Step-by-step explanation:
Let C be the speed of the current
Let D be the distance between Chan's house and the park
We know that Distance, D, is = Speed x Time
-----
Chan's speed going upstream is (8 - C)mph.
That gives us:
D = (8-C)(3 hr)
Chan's speed going downstream is (8+C)mph
So we have:
D = (8+C)(2 hr)
We know that the d is the same for these two equations, so:
(8-C)(3 hr) = (8+C)(2 hr)
24 - 3C = 16 + 2C
5C = 8
C = (8/5) or 1 3/5 mph
Answer:
47/10 - 3.2
Step-by-step explanation:
Given
Dolphin = 3.2
Bird = 47/10
Required
What is the vertical distance between both
Using a vertical scale;
Represent the bird "above sea level" position with positive and dolphin at "below sea level" position with negative.
The vertical distance between them is as follows;
Distance = +[Above The Sea] - [Below The Sea]
Distance = +47/10 - 3.2
Distance = 47/10 - 3.2
Hence, the vertical distance between both is 47/10 - 3.2
