Answer:
Let 'a' be the first term, 'r' be the common ratio and 'n' be the number of terms
Series = 2+6+18.......= 2+2•3¹+ 2•3².......= 728
Now,
So,
Therefore, number of terms is 6
D is a line, K is a point, beta is a plane and PY is a line segment.
Assuming that the actual question reads lines b and c are perpendicular to line d
we are given that c is perpendicular to line d and parallel to line a. Since b is also perpendicular to line d, a b and c must all be parallel (draw it out will make a lot more sense)
So b is also parallel to line a
(4,1) is a possible solution. Hope this helps. :)
Y - y₁ = m(x - x₁)
y - 3 = -6(x - 0)
y - 3 = -6(x) + 6(0)
y - 3 = -6x + 0
+ 3 + 3
y = -6x + 3
