Adeep-sea diver must descend and ascend in short steps to equalize pressure on his body. if the diver rises toward the surface too fast, he may suffer from a physical condition called "the bends." suppose the diver started at 82 feet below the surface and rose in 5 steps of 15 feet each. use an integer to describe his new position in relation to the water surface.

-7 feet

Step-by-step explanation:

The total distance the diver rose is 5*15 = 75 feet

If we take the zero at the water surface, then the initial position, that is, 82 feet below the surface has to be considered as -82. The 75 feet risen by the diver is a positive quantity, then his new position, in relation to the water surface, is -82 + 75 = -7 feet, i. e. 7 feet below the surface.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
