Is triangle ABC a right triangle? no, because none of the slopes of the line segments forming the legs are opposite reciprocals
no, because none of the slopes of the line segments forming the legs are equal
yes, because BC is perpendicular to AC
yes, because AB is perpendicular to AC

yes because BC is perpendicular to AC

Step-by-step explanation:

BC slope is 6/2 which is 3

AC slope is -3/9 which reduces to -1/3

3 and -1/3 are opposite reciprocals and therefore the lines are perpendicular

C yes, because BC is perpendicular to AC

Step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
