Aresearch ship lowers a probe into the ocean to explore an underwater trench. The probe starts on a crane 16 feet above the surface and is lowered at a rate of 9.8 feet per minute. Write an expression for the depth of the probe after m minutes. What is the depth of the probe after 90 minutes? of the probe after m minutes​

The probe starts at 16 feet above sea level then it is lowered 9.8 feet per minute.

Start at 16 and then subtract 9.8 times the number of minutes:

Depth = 16 - 9.8m

Now to find the depth after 90 minutes replace m with 90 and solve:

Depth = 16-9.8(90)

Depth = 16 - 882

Depth = -866 feet

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
