Find the distance between (-6,4) and (-2,1)

zhannawk [14.2K]

Answer:

$d=2.65$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the formula to find distance d:

$d=\sqrt{(-2-(-6))^2-(1-4)^2}$

$d=\sqrt{(-2+6))^2-(-3)^2}$

$d=\sqrt{(4)^2-9}$

$d=\sqrt{16-9}$

$d=\sqrt{7}$

$d=2.65$

396,391,000 niños de esa edad hay en India

Step-by-step explanation:

We have that:

India has 1,189,173,000 habitants.

A third of this is smaller than 15.

How many people smaller than 15 are there in India?

(1/3)*1,189,173,000 = 396,391,000

There are 396,391,000 people smaller than 15 in India.

How many different three-digit numbers can be written using digits from the set 5, 6, 7, 8, 9 without any repeating digits?

suter [353]

Answer: 60 different numbers can be formed

Step-by-step explanation:

Note that we have 5 different digits, and we must select 3 of them. They should not be repeated

The order of selection is important in this case, because the number 532 is not the same as the number 235.

So we have a permutations problem, where we have a set of n elements and we want to choose r from them.

Then we define the permutacion as:

$nPr=\frac{n!}{(n-r)!}$

In this case note that n=5 because there are 5 elements in the set.

r = 3 because we combine the elements to form three-digit numbers

Then:

$5P2=\frac{5!}{(5-3)!}$

$5P2=\frac{5!}{2!}$

$5P2=\frac{5*4*3*2!}{2!}$

$5P2=5*4*3$

$5P2=60$
