Nicala's Post

okay we had our exams and we learned the rest of chapter five which was about exponents which we learned in aleks and logs which we should have learned in algebra 2 but i did not understand it then and do not understand now. okay we took our exam thursday which i failed horrible and we started doing fourteen aleks friday and will finish them this weekend and tomorrow we start the fifty bonus aleks for the extra fifty points in class which i need. one of things i learned on aleks is how to do translation of a vector.

Example Problem

A vector with an initial point of (-6,-2) and terminal point of (-5,3) is translated so that its initial point is at the origin. Find its new terminal point.

To find the terminal point you have subtract them from each other.
you subtract -5 minus -6. since you are subtracting and the six is negative the six becomes positive which gives you 1 as your first new terminal point.
next you subtract 3 minus -2 since you are subtracting and the two is the two becomes positive
which gives you 5 as your second new terminal point.
the answer is (1,5)
