Answer:
(0,0)
Step-by-step explanation:
They intersect at point (0,0)
Let us use the formula with the point (4,5) and (0,2)
![\begin{gathered} d=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2}=\sqrt[]{(4-0)^2+(5-2)^2} \\ =\sqrt[]{16+9}=\sqrt[]{25}=5 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20d%3D%5Csqrt%5B%5D%7B%28x_1-x_2%29%5E2%2B%28y_1-y_2%29%5E2%7D%3D%5Csqrt%5B%5D%7B%284-0%29%5E2%2B%285-2%29%5E2%7D%20%5C%5C%20%3D%5Csqrt%5B%5D%7B16%2B9%7D%3D%5Csqrt%5B%5D%7B25%7D%3D5%20%5Cend%7Bgathered%7D)
Answer:
Step-by-step explanation:
A=2i+3j+4k
B=i-2j+3k
Sum of the vectors:
A + B = 2i+3j+4k + i-2j+3k = 3i + j + 7k
Direction of the sum of the vectors:
Answer:
domain - (-infinity,infinity)
range - (-infinity, 2]
axis of sym - x=-1
y int - (0,-1)
at what value (row 1) - (-1,2)
Step-by-step explanation:
domain is side to side, it never ends bc of the arrows
range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)
the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up
