Wo friends drive off in different directions from the same place. one heads north at 40 miles per hour, while the other heads east at 35 miles per hour. complete an equation for the distance between the friends after t hours. distance = preview

The distance between the friends at the end of one hour can be found from the Pythagorean theorem to be
.. d = √(40^2 +35^2) = √2825 = 5√113 ≈ 53.15 . . . . miles

Since the friends are continuing in the same directions at the same speeds, their distance apart will increase by this amount each hour.

distance = t*5√113 . . . . miles after t hours

The correct option is;

The line of best fit is not reasonable because it has more points below it than above it.

Step-by-step explanation:

Here we note that there are a total of seven points in the scatter plot and there are five of the points below the line of best fit and just two above the line.

Of the five points below the line of best fit, four are just about touching the underside of the line while one of the two points above the line is just about touching the line.

The proper positioning of the line can be reviewed, therefore, with a line drawn through the four points presently touching the underside of the line of best fit.
