Please help :) A B&C form the vertices of a triangle.
CAB = 90°, ABC = 70° and
AC = 9.5.
Calculate the length of AB rounded to 3 SF.

And please explain how :)
Thanks

Karianne and lucius are analyzing a linear function on a graph. karianne says that unit rate is equal to rate of change, but that slope is calculated differently. lucius says that unit rate, rate of change, and slope are calculated the same way. who is correct? explain your answer.
