Find the sum of the geometric series 9000-900 +...+ 0.009
bagirrra123 [75]

Based on the calculations, the sum of this geometric series is equal to 9,990.

<h3>The standard form of a geometric series.</h3>

Mathematically, the standard form of a geometric series can be represented by the following expression:

\sum^{n-1}_{k=0}a_1(r)^k

Where:

  • a₁ is the first term of a geometric series.
  • r is the common ratio.

<h3>How to calculate the sum of a geometric series?</h3>

Also, the sum of a geometric series is given by this mathematical expression:

S=\frac{a_1(1-r^n)}{1-r}

<u>Given the following data:</u>

  • First term, a = 9000.
  • Common ratio, r = 900/9000 = 0.1

Substituting the given parameters into the formula, we have;

S=\frac{9000(1-0.1^3)}{1-0.1}\\\\S=\frac{9000(1-0.001)}{1-0.1}

S = 9000(0.999)/0.9

S = 8,991/0.9

S = 9,990.

The solution to the system of equation below is (−2, −1).
diamong [38]

Answer:

Solution is given by (-2,-1)

Step-by-step explanation:

2x-3y = -1

11x-9y = -13

Multiplying equation 1 by -3  and adding it to equation 2 ,we get

-6x+9y = 3

11x -9y = -13

___________

5x  =   -10

gives x = -2

plugging this value in equation (1) ,we get

2(-2) -3y = -1

-4 -3y =-1

 -3y =-1+4

 -3y =3

    y = -1

solution is (-2,-1)
