What is the sum of the first six terms of the geometric series? 2 – 6 18 – 54 ...

Law Incorporation [45]

The sum of the first six terms of the geometric series is -364.

A geometric series is a sequence of terms in a fixed common ratio.

Apparently, the expression "geometric progression" comes from the "geometric mean" (Euclidean term) of segments of lengths a and b: it is the length of the side c of a square whose area is equal to the area of the rectangle. a and b. May

The series given is

2 – 6 + 18 – 54 + ...

The sum of n terms of a geometric series is given by

Sn=a1 * 1 - rn/1 - r

here the first term is 2

r = -6 /2 = -3

S = 2 (1-(-3)⁶)/(1-(-3))

S = -364

Therefore the sum of the First six terms of the geometric series is -364 .

Isabella ran the 100-meter dash five times. The time it took her to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.

Stells [14]

Given:

Number of 100-meter races = 5

The time it took Isabella to complete each race, in seconds, was 12.7, 12.807, 12.78, 12.08, and 12.087.

To find:

The decimals in order from greatest to least.

Solution:

The time it took Isabella to complete each race, in seconds, was shown below:

12.7, 12.807, 12.78, 12.08, 12.087

We need to arrange this data in descending order.

In all 5 numbers the digits before decimals are same. On comparing the digits on the tenth place and hundredth place, we get

12.807 > 12.78 > 12.7 > 12.087 > 12. 08

Therefore, the required order of given data is 12.807, 12.78, 12.7, 12.087, 12. 08.

What is the volume of the rectangle pyramid show below?

Maksim231197 [3]

Answer:

Option (3)

Step-by-step explanation:

Volume of a rectangle = $\frac{1}{3}(\text{Area of the rectangular base)(\text{Height})}$

Area of the rectangular base = Length × Width

= 7 × 8

= 56 square in.

Height of the pyramid = 9 in.

Therefore, Volume of the given pyramid = $\frac{1}{3}(56)(9)$

= 168 cubic in.

Option (3) will be the correct option.
