Explain in detail how to find the vertex: <br> y=-2x^2 + 2x + 3
Cerrena [4.2K]

\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{-2}x^2\stackrel{\stackrel{b}{\downarrow }}{+2}x\stackrel{\stackrel{c}{\downarrow }}{+3} \qquad \qquad  \left(-\cfrac{ b}{2 a}~~~~ ,~~~~  c-\cfrac{ b^2}{4 a}\right)


\bf \left(-\cfrac{2}{2(-2)}~~,~~3-\cfrac{2^2}{4(-2)}  \right)\implies \left( \cfrac{1}{2}~~,~~3+\cfrac{4}{8} \right)\implies \left(\cfrac{1}{2}~~,~~\cfrac{28}{8}  \right) \\\\\\ \left(\cfrac{1}{2}~~,~~\cfrac{7}{2}  \right)\implies \left(\frac{1}{2}~,~3\frac{1}{2}  \right)

Identify the 12th term of a geometric sequence where a1 = 8 and a6 = −8,192.
vodka [1.7K]
Geometric sequence
a_{n}=a_{1}*r^{n-1}
r=common ratio
a1=first term
find r

a1=8
a6=-8192
-8192=a_{6}=8*r^{6-1}
-8192=8*r^{5}
divide both sides by 8
-1024=8*r^{5}
take 5th root of both sides
-4=r
sub
a_{12}=8*(-4)^{12-1}
a_{12}=8*(-4)^{11}
a_{12}=8*-4194304
a_{12}=-33554432
