Find the coordinates of endpoint A of the line segment with the given endpoint B(1, 3) and midpoint M(-2-6).

The endpoint would be  (-5, -15).

Step-by-step explanation:

:)

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

3; 9 is 8 to -4
