What are the values of a 1 and r of the geometric series? 1 3 9 27 81 a 1 = 1 and r = one-third a 1 = one-third and r = 1 a 1 =

Paha777 [63]

Answer:

a₁ = 1

r = 3

Step-by-step explanation:

Since it’s a geometric series then

a₁ = 1 ( because 1 is the first term of the series)

3/1 = 9/3 = 27/9 = 81/27 = 3 then r=3.

What's is an equation of the line that passes through the point(-3,-1) and is perpendicular to the line x-2y=6

katrin2010 [14]

Answer:

$y+1=-2(x+3)$

Step-by-step explanation:

Slope is negative reciprocal when two lines are perpendicular

m1=1/2 therefore m2=-2

The equation of the line in point-slope form is given as

$y-y_1=m_2(x-x_1)$

Here m=-2 and (x1, y1)=(-3, -1)

Therefore,

$y+1=-2(x+3)$
