Answer:
AB = BC = 2√2
Step-by-step explanation:
Start by focusing on the 45 degree angle. The unknown AB is the side adjacent to this 45 degree angle, and the hypotenuse is known to be 4.
Thus,
cos 45 degrees = adj / hyp = AB / 4, or
AB = 4 cos 45 degrees = 4 (1 / √2) =
4 √2
----------- * --------- = 2√2
√2 √2
Since this is a 45-45-90 triangle, the two shorter sides are equal, and so BC = 2√2 also.
1) The first graph is the graph of f(x) traslated 5 units to the left, then the equation of this graph is: y=(x+5)^2
2) The second graph is the graph of f(x) traslated 5 units upward, then the equation of this graph is: y=x^2+5
3) The third graph is the graph of f(x) traslated 5 units downward, then the equation of this graph is: y=x^2-5
4) The fourth graph is the graph of f(x) traslated 5 units to the right, then the equation of this graph is: y=(x-5)^2
