Explanation:
Hello,
Here i am using vectors
\vec{AB}=\vec{DC}=3\vec{i}+3\vec{j}AB=DC=3i+3j
==> AB//DC and AD//BC (definition of a translation)
The quadrilater ABCD is a parallelogram:
so
1) his diagonals have the same length;
2) his diagonals are cutting in the middle.
(these are proprieties of a parallelogram)
Answer:
Modulus of Elasticity = 4.350×10⁶ lb/in²
q'n = 60.33 lb/in²
Side friction = 6.372 lb/in²
Explanation:
See workings in picture below.
Answer:
1.636
Explanation:
Slope is given by change in y coordinates against change in x coordinates. Here, change in y will be 973.738-660.974= 312.764 and change in x will be 437.279-246.060=191.219
The slope, m will be 312.764/191.219=1.6356324423828
Rounding off, the slope is 1.636 to four significant figures
