A(-6,4) and E(6,0) slope m = (4 - 0) / ( -6-6) = 4/-12 = -1/3
perpendicular, slope is opposite and reciprocal so slope = 3
A perpendicular bisector<span> of a </span>line<span> segment is a </span>line <span>segment </span>perpendicular<span> to and passing through the midpoint
</span>Midpoint: so x = ((-6+6)/2 = 0 and y = (4+0)/ 2 = 2 so M = (0,2)
equation of perpendicular line: y = 3x + 2
answer: equation: y = 3x + 2 point lies on perpendicular bisector: (0,2)
Annual interest is P*r^t, r is 0.05 here, t is 9/12=3/4=0.75 P*0.05^0.75=120 use your calculaor: P= 120÷ (0.05)^0.75=1135 so he invested about 1135 dollars <span><span><span><span>
