In cirlce m segment AB is tangent to the cirlce at point c. AB has endpoints such that AM is perpendicular to BM, AC =9 and BC=4. What is the length of the radius of circle M

6 units

Step-by-step explanation:

look at the attachment

r= 4/tan∅ ⇒ tan∅= 4/r

tan∅= r/9

4/r= r/9

r² = 36

r= 6

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.

good luck on your studies! : )
