You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. The values of r and s are equidistant from the center by an unknown quantity u.

WebA geometric sequence is a sequence where the ratio r between successive terms is constant. The general term of a geometric sequence can be written in terms of its first term a1, common ratio r, and index n as follows: an = a1rn − 1. A geometric series is the sum of the terms of a geometric sequence. The n th partial sum of a geometric ... WebAlgebra. Factor s^2-81. s2 − 81 s 2 - 81. Rewrite 81 81 as 92 9 2. s2 − 92 s 2 - 9 2.

WebMay 9, 2024 · Given the context, it seems as though you meant to ask "If dim ( S 2) = 3 and S 1 is a subspace of S 2, then what are the possible dimension of S 1 ?" to which the answer would be 0, 1, 2 or 3. As for the second half of the question, the shortest answer is that to be a subspace of a space, one must not only be a vector space but also a subset ... WebA geometric series is a series whose related sequence is geometric. It results from adding the terms of a geometric sequence .
