V * v = v^2
v * -8 = -8v
8 * v = 8v
8 * -8 = -64

v^2 - 8v + 8v - 64

Mrs. Jones bought 6 kilograms of rice. After filling 10 containers with the same
9966 [12]

There are 514 gram rice in each container.

Step-by-step explanation:

Given,

Amount of rice = 6 kg

1 kg = 1000 g

6 kg = 6*1000 = 6000 g

Number of containers  = 10

Rice left = 860 g

Let,

x be the amount in each container.

Total amount of rice - Number of containers*Amount in each container = Amount of rice left

6000-10x=860\\6000-860=10x\\5140=10x\\10x=5140

Dividing both sides by 10

\frac{10x}{10}=\frac{5140}{10}\\x=514

There are 514 gram rice in each container.

2,-10,50,-250,.. Geometric sequence
nikklg [1K]

This question is incomplete, here is the complete question

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?

The recursive formula for this geometric sequence is:

a_{1} = 2; a_{n} = (-5) • a_{n-1}

Step-by-step explanation:

To find the recursive formula for a geometric sequence:

  1. Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
  2. Find the common ratio. (The number you multiply or divide.)
  3. Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.

The recursive formula is:

a_{1} = first term;  a_{n} = r • a_{n-1}  , where

  • a_{1} is the first term in the sequence
  • a_{n-1} is the term before the nth term  
  • r is the common ratio

∵ The geometric sequence is 2 , -10 , 50 , -250

∴ a_{1} = 2

- To find r divide the 2nd term by the first term

∵ r=\frac{a_{2}}{a_{1}}

∴ r=\frac{-10}{2}=-5

- Substitute the values of a_{1} and r in the formula above

∴  a_{1} = 2; a_{n} = (-5) • a_{n-1}

The recursive formula for this geometric sequence is:

a_{1} = 2; a_{n} = (-5) • a_{n-1}
