Answer:

106°

Step-by-step explanation:

For the equilateral ΔBCD all angles are 60° (180/3 = 60).

m∠ADB is 67° Since the triangle is isosceles the base angles are =.

m∠ ABD will be 180 - (67+67) = 46°.

m∠DBC = 60° so m∠ABC = 46 + 60 = 106°

The explicit formula for the geometric sequence -1/9, 1/3, -1, 3, -9, ... is -1/9(-3)^x-1 . What is the common ratio and recursi

KATRIN_1 [288]

Answer:

r=3
$\left\{\begin{array}{ccc}a_1=-\frac{1}{9}\\a_n=-3a_{n-1}\end{array}\right$

Step-by-step explanation:

Given the sequence

$-1/9, 1/3, -1, 3, -9, ...$

The common ratio is determined by the division of term by the previous term.

Common Ratio, $r=\frac{1/3}{-1/9} =\frac{-1}{1/3} =\frac{3}{-1}=-3$

A recursive formula is a formula that defines each term of a sequence using preceding term(s).

For the given sequence, the recursive formula is:

$\left\{\begin{array}{ccc}a_1=-\frac{1}{9}\\a_n=-3a_{n-1}\end{array}\right$
