F(x)=2+3cosπ/10(x−3) find the third positive value of x for which f(x) = 4.

The anwser cause i do not understand just plez

Which value of y will make the inequality y< -1 false?

Line segment eg is partitioned by point f in the ratio 1: 1. point e is at e (0, 4), and point f is at (1, 3). what are the coordinates of point g? (−1, 5) (2, 2) (3, 1) (4, 0)
