Study the geometric sequence {-4, -84, -1764, -37044, ...}.

Nonamiya [84]

Answer:

$\bold{a_n=(-4)21^{n-1}}$

Step-by-step explanation:

$a_1=-4\,,\ a_2=-84\,,\ a_3=-1764\,,\ a_4=-37044\quad\implies\ \ r=21$

{-84:(-4)=21 and -1764:(-84)=21 and -37044:(-1764)=21}

geometric sequence formula: $a_n=a_1r^{n-1}$

$a_1=-4\quad and \ \ r=21$

$a_n=(-4)21^{n-1}$

If the slope of line l is x, and the slope of line m is x+2, and l⊥ m, what is x?

salantis [7]

Answer:

The answer to your question is: x = -1

Step-by-step explanation:

Data

slope of l = x

slope of m = x +2

they are ⊥

Process

If they are ⊥, then, x + 2 = - 1/x

x(x + 2) = -1

x² + 2x = -1

x² + 2x + 1 = 0

(x + 1)² = 0

x + 1 = 0

x = -1
