Answer:
11, 14, 17, 20
Step-by-step explanation:
An arithmetic sequence has a common difference d between consecutive terms.
Consider 2, 6, 18, 54
6 - 2 = 4, 18 - 6 = 12, 54 - 18 = 36 ← no common difference, not arithmetic
Consider 3, 6, 12, 24
6 - 3 = 3, 12 - 6 = 6, 24 - 12 = 12 ← no common difference, not arithmetic
Consider 11, 14, 17, 20
14 - 11 = 3, 17 - 14 = 3, 20 - 17 = 3 ← common difference of 3, so arithmetic
Consider 7, 11, 13, 18
11 - 7 = 4, 13 - 11 = 2, 18 - 13 = 5 ← no common difference, not arithmetic
The arithmetic sequence is 11, 14, 17, 20
When converting from meters to centimeters, you have to multiply the number by 100 because there are 100 centimeters per meter.
8.6m x 100= 860cm
Quan bought 860 centimeters of fabric.
Answer:
Yes
Step-by-step explanation:
Given
Required
True or false? With reason
The expression is true and the reason is as follows.
In trigonometry:
So:
is equivalent to:
![0 * [tan(1).tan(2).......tan(89)] = 0](https://tex.z-dn.net/?f=0%20%2A%20%5Btan%281%29.tan%282%29.......tan%2889%29%5D%20%3D%200)
When 0 is multiplied to an expression, the result is 0
So, the above expression becomes:
<em>Since both sides of the equation are equal, then Ravi is correct</em>
