Answer:

10

Step-by-step explanation:

d=\sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2}   }

d=\sqrt{(-5-(-5))^{2}+(-3-7)^{2}  }

d=\sqrt{(0)^{2}+(-10)^{2}  }

d=\sqrt{100} \\\\d=10

hope this helps!

Three brothers have ages that are consecutive even integers the product of the first & third boys ages is 20 more than twice
Agata [3.3K]
Let's say X is the first brother's age
x+2 is second brother, and x+4 is the third brother
Since the product of the first and third boy x(x+4) is 20 more than twice (20+x(x+2), our equation is x(x+4)=20+2(x+2)
Simplify from there and see what you get.

A coordinator will select 6 songs from a list of 9 songs to compose an event's musical entertainment lineup. How many different
g100num [7]

Answer:

84 different lineups are possible

Step-by-step explanation:

The order in which the songs are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

6 musics from a set of 9. So

C_{9,6} = \frac{9!}{6!(9-6)!} = 84

84 different lineups are possible
