The position of an open-water swimmer is shown in the graph. The shortest route to the shoreline is one that is perpendicular to
Stolb23 [73]

Answer:

Step-by-step explanation:

To define the perpendicular line we need to first know the slope of the reference line graphed.

m=(y2-y1)/(x2-x1) we have points (0,5) and (2,1)

m=(1-5)/(2-0)

m=-4/2

m=-2

For lines to be perpendicular their slopes must satisfy

m1m2=-1, we have a line with a slope of -2 so

-2m=-1

m=1/2, so our perpendicular line is so far

y=x/2+b, it must have point (3,2) so we can solve for b

2=3/2+b

b=1/2, so the swimmer will travel along the line

y=x/2+1/2

3. 5/6

<h3>How to explain the fraction?</h3>

1. 6 1/4 + 2 2/5

LCM of 20

6 1/4 + 2 2/5.

6 5/20 + 2 8/20

= 8 13/20

2. 1 1/5 × 2 1/3

= 6/5 × 7/3

= 42/15

= 14/5

= 2 4/5

3. 3 1/3 - 2 1/2

= 3 2/6 - 2 3/6.

= 5/6
