Hmmm im on the same question so i think its this
the height can be given as
AB = a sin theta
here a = 4 and theta is 60 so
AB = 4 sin 60 = 4 × √3/2 = 2√3
so area of a parallelogram is
= base × height
= 7 × 2√3 = 14√3
Take a look at f(x) = -x + 1. Its slope is negative and its y-intercept is +1.
Right away, we can eliminate the 3rd and 4th graphs, because they show positive slopes for x≤1.
Take another look: f(x) = -x + 1. When x = 0, y = 1. Thus, the y-intercept is (0,1).
The first graph shows this intercept correctly; the second does not. So the correct answe is "the first graph."
Find A ∩ B if A = {3, 6, 9, 12} and B = {2, 4, 6, 8, 10, 12}. Ø {6, 12} {2, 3, 4, 6, 8, 9, 10, 12}

That is the intersection sign
that means find the terms common to both
the ones common to bboth are 6 and 12
so then it would be {6,12}
