Find the sum of this infinite geometric series where a1=0.3 and r=0.1

ratelena [41]

Answer:

1/3

Step-by-step explanation:

The formula for computing the sum of an infinite geometric series is

$S=\frac{a_1}{1-r}$ where r is between -1 and 1 and $r$ is the common ratio, and $a_1$ is the first term of the series.

So let's plug in:

$S=\frac{0.3}{1-0.1}$

$S=\frac{0.3}{0.9}$

$S=\frac{3}{9}$ I multiplied bottom and top by 10.

$S=\frac{1}{3}$ I divided top and bottom by 3.

The sum is 1/3.

Perform the indicated computation. Write the answer in scientific notation. 12x10^4\3x10^−2

Paul [167]

Let us consider the given expression:

$\frac{12 \times 10^{4}}{3 \times 10^{-2}}$ in the scientific notation.

= $\frac{12 \times 10^{4} \times 10^{2}}{3 }$

[Using the law of exponents, which states

$a^{m} \times a^{n} = a^{m+n}$ ]

= $\frac{12 \times 10^{6}}{3}$

On dividing, we get

= $4 \times 10^{6}$

Hence, it is the required scientific notation of the given expression.

8 + 4a + 6.2 - 9a =

Strike441 [17]

Answer: 14.2 - 5a

Work: I just did "CLT" of "Combine Like Terms". I did 8 + 6.2 First because 8 is first, then I did 4a - 9a which is -5a, and I combined them, and got the answer. I hope this helps, and stay safe! :)
