the submarine moves 17.5 feet every minute

Step-by-step explanation:

2100 / 120(minutes) = 17.5(minute)

and maybe you could divide 17.5m by 60 to get how many feet it moves every second, so

17.5m / 60 = 0.2916666

the submarine moves 0.2916666 feet below the surface every second

but this is coming from a 7th grader sooo

tell me if this isn’t right and I’ll try again!

answer:   rlly

step-by-step explanation:

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
