Answer:

The common ratio is -6

Step-by-step explanation:

The given sequence is

Answer:

Choice D is correct answer.

Step-by-step explanation:

We have given a geometric sequence.

\frac{1}{18},\frac{-1}{3},2,-12,...

We have to find the common ratio of the given geometric sequence.

Common ratio of the geometric sequence is defined as the ratio between two consecutive terms.

It is denoted by r.

Hence, \frac{-1/3}{1/18}

\frac{-18}{3}

-6  is common ratio of the given geometric sequence which is the answer.

If 2x - 5y – 7 = 0 is perpendicular to the line ax - y - 3 = 0 what is the value of a ?
faltersainse [42]

Answer:

D) a = - 5/2

Step-by-step explanation:

2x -5y - 7 = 0

5y = 2x - 7

y = 2/5 x - 7

the slope of this line is therefore 2/5 (factor of x).

the perpendicular slope is then (exchange y and x and flip the sign) -5/2, which is then a and the factor of x.

It is not digital because that would something like applepay. It is also nt representative, since that would be something like food stamps. Commodity money is also a bad answer, since it is goods. You answer would be fiat money, which is paper tender issued by the government. Hope this helps.

HELPZ. Find value of x and all the measures of all angel
bagirrra123 [75]

Answer: x = 40

have: ∠A + ∠B + ∠C + ∠D = 180°

⇔ x + 6 + x + 4 + x +10 + x = 180°

⇔ 4x + 20 = 180

⇔ x = (180 - 20)/4

⇔ x = 160/4 = 40
