A submarine is rising from a depth of -50 meters at a speed of 0.2 meter per second. Write an equation that represents the depth of the submarine as it rises to the surface.
Hmmm. how about
y = -50 + 0.2x
You can supply the units.
To represent the depth of the submarine as it rises to the surface, we can use the equation:
depth = initial depth + (rate of increase * time)
In this case, the initial depth of the submarine is -50 meters, and the rate of increase (speed) is 0.2 meters per second. Since the submarine is rising, the depth is increasing, so the rate of increase will be positive.
Putting these values into the equation, we get:
depth = -50 + (0.2 * time)
Thus, the equation that represents the depth of the submarine as it rises to the surface is depth = -50 + 0.2t, where t represents the time elapsed.
