Find an explicit rule for the nth term of a geometric sequence where the second and fifth terms are -6 and 162, respectively. Pl
kicyunya [14]
Hello,

u_{0} =a\\
 u_{1} =a*r\\
 u_{2} =a*r^{2}=-6\\
 u_{3} =a*r^{3}\\
 u_{4} =a*r^{4}\\
 u_{5} =a*r^{5}=162\\
....\\
\boxed{ u_{n} =a*r^{n}} \\

\dfrac{ 162}{-6} = \dfrac{ u_{5} }{ u_{3}} = \dfrac{ a*r^{5}}{ a*r^{2}} =r^3= -27\\
==\ \textgreater \  r=-3\\

 u_{2} =a*r^{2}=-6=a*(-3)^2 \ ==\ \textgreater \  a=-\frac{6}{9} =-\frac{2}{3}\\


\boxed{ u_{n} =-\frac{2}{3}*(-3)^{n}=(-1)^{n+1}*2*3^{n-1}} \\

The slope of a line that is perpendicular to a line whose slope is 3/8 is
Molodets [167]

Answer:

-8/3

Step-by-step explanation:

We know that lines that are perpendicular have slopes that multiply to -1

m1 * m2 = -1

We know one slope is 3/8 and are looking for the perpendicular slope m2

3/8 * m2 = -1

Multiply each side by 8/3 to find m2

3/8*8/3 *m2 = -1*8/3

m2 = -8/3
