Seth is using the figure shown below to prove pythagorean theorem using triangle similarity:

in the given triangle abc, angle a is 90o and segment ad is perpendicular to segment bc.

the figure shows triangle abc with right angle at a and segment ad. point d is on side bc.

which of these could be a step to prove that bc2 = ab2 + ac2?

by the cross product property, ab2 = bc multiplied by bd.
by the cross product property, ac2 = bc multiplied by bd.
by the cross product property, ac2 = bc multiplied by ad.
by the cross product property, ab2 = bc multiplied by ad.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the answer is 0052

0 0 5 2

5 0 2 6 3 5

− 0

2 6

− 0

2 6 3

− 2 5 0

1 3 5

− 1 0 0

3 5

210/22 = 9.55

since he can't take part of a person to the game the answer is 9 people

hope this !
