Step-by-step explanation:

2/3

Rounded to 3 significant figures

Rounding up to a significant figure means, you limit the number to have only 3 significant digit only, which means 0 would not be counted, because it is insignificant.

In rounding up numbers, number 1 to 4 is rounded up to 0, while numbers 5 to 9 are rounded up to 1. Starting exactly after the figure of concern.

2/3 equals 0.666666666666recurring

Rounded up to 3 significant figures, let's have four significant figures first

0.6666

The fourth significant figure is 6, rounding it up gives 1. Then 1 will be added to the third significant figure

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
