A structural steel column is 20 meters long and has a square cross-section with a side length of 10 cm. A force of 6 × 105 newtons compresses the column. (This force is equivalent to the weight of several trucks.) Estimate by how much the column’s length decreases, and compare the change in length with the original length of the column. (First, divide the force by the cross-sectional area to calculate the stress σ. When you calculate the area, remember to convert to meter2. Then, use the equation to solve for the change in length, .) Show the steps in your work.

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
