Mathematics: 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

19-11.3m

Depth of the probe after 90 minutes is given by

$19-1017=-998\text{ feet}$

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

$\text{ Since we know the formula for distance}\\\\Distance=Speed\times time\\\\Distance=11.3 \times m\\\\Distance= 11.3m$

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

19-11.3m

Since we have given time = 90 minutes

$Distance=Speed\times time\\\\Distance=11.3\times 90\\\\Distance=1017\text{ feet}$

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

$19-1017=-998\text{ feet}$

16*x*0+2*x*2*y-1=11

Step-by-step explanation:

ok so first we substitute-

16*2*0+2*2*2+4-1

=0+8+3 (order of operations)

=11
