The position of a submarine relative to the water surface was −31 1 /4 feet. A downward navigational maneuver increased its depth by 17 1/2 feet. What is the position of the submarine now relative to the water surface? Enter your answer as a mixed number, in simplified form, in the box.

3,000,540

step-by-step explanation:

alaska, florida, nevada, south dakota, texas, washington and wyoming, tenessee and new hampshire.

step-by-step explanation:

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.

answer is  

c.

56

hope you get this right
