Answer:
Step 1: Rewrite the first two columns of the matrix.
Step 2: Multiply diagonally downward and diagonally upward.
Step 3: Add the downward numbers together.
Step 4: Add the upward numbers together.
Step-by-step explanation:
hope this helps ;)
(-5, 2)(-9,9)
D = √( (x2 - x1)^2 + (y2 - y1)^2 )
D = √( (-9+5)^2 + (9 - 2)^2 )
D =√( (-4)^2 + (7)^2 )
D = √( 16 + 49 )
D = √65
D = 8
First we combine the parenthesis to get 9/(-2-i) then we multiply both the numerator and the denomenator by the conjugate of -2-i (whic is -2+i) to get (-18+9i)/5
The answer 0.1, 0.136, 0.652, 0.87
