Answer:

First, she notes down her current position as point A.

Then she checks out on the other bank, a big stone (point B) or something (which is not too far from her), she then goes along the bank to the point C so that BC is perpendicular with the bank.

If she can mark down the distance she walked AC and the angle BAC, then she can calculate the width of river (AB) by formula:

BC = AC x tan(BAC)

Hope this helps!

what is the y intercept of the line with a slope of - 4/7 that also passes through the point (7 , - 7/2) ?

kondor19780726 [428]

The answer is the last option: $\frac{1}{2}$

Explanation:

1. You have that the equation of the line is:

$y=mx+b$

Where $m$ is the slope of the line and $b$ is the intercept with the y-axis.

2. Therefore, you must find $b$ .

3. Then, you must substitute the points given in the problem and the slope into the equation of the line and solve for $b$ , as following:

$y=mx+b\\-\frac{7}{2}=(-\frac{4}{7})(7)+b\\-\frac{7}{2}=-4+b\\b=\frac{1}{2}$
