Aresearch ship lowers a probe into the ocean to explore an underwater trench. the probe starts on a crane 19 feet above the surface and is lowered at a rate of 11.3 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?

Depth of the probe after m minutes is given by

Depth of the probe after 90 minutes is given by

Step-by-step explanation:

Since we have given that

Position at which the probe starts on a crane above the surface = 19 feet

Speed at which it is lowered = 11.3 feet per minute

Time taken = m minutes

Expression will be given by

So, Depth of the probe after m minutes is given by

Since we have given time = 90 minutes

then, Depth of the probe after 90 minutes is given by

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
