The distance (r) between any two points (a,b) and (c,d) is :—

Putting the values,



The distance between the points is √41
<h2>
Mass conversion</h2>
<em>Mass is the amount of matter that a body possesses and its unit in the </em><em>international system</em><em> of units is the</em><em> kilogram.</em>
<h3>How many kilograms is 2 pounds?</h3>
- <em>Knowing that </em><em>1 pound is 2.205 kilograms.</em>
<h3><em>
Therefore ⇒ 2 lb * 1 kg / 2.205 lb = 0.907 kg</em></h3>
<em />
Answer: In 2 pounds there are 0.907 kilograms.
When the linear dimensions are changed by a factor of 2, the area is changed by a factor of 2^2 = 4.
The total surface area is multiplied by 4.
Answer by JKismyhusbandbae: a^n = 4n + 1
Explanation: So the regular formula for sequence is:
an = a1 + d (n – 1)
a1 = the first term.
d = common difference
n = term number
So in the formula form it would look like this: an: 5 - 4(n-1)
Then I like to solve it as if it were a linear equation in the end you get: a^n = 4n + 1
