A marine submersible descends more than 45 feet below sea level. As it descends from sea level, the change in elevation is -5 feet per second. For how many seconds does it descend? Write an Inequality.

answer: '

the distance between points l and m

step-by-step explanation:

answer: what are the following choices

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

d. you cannot tell because there are no values shown.
