If a rectangular piece of paper ABCD. Point M is the midpoint of the diagonal AC, and point E is on the side of BC, fold △DCE along the line DE so that point C falls on the diagonal AC at point F , connect DF, EF. If MF=AB, then ∠DAF =? degree.

How do you multiply a mixed fraction by a regular fraction

Come up with a new linear function that has a slope that falls in the range 10 m − < < . choose two different initial values. for this new linear function, what happens to the function’s values after many iterations? are the function’s values getting close to a particular number in each case?

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
