This table gives a few (x, y) pairs of a line in the coordinate plane. (-72,25)
(-54,13)
(-36,1)
What is the y-intercept of the line?

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)

21/58.

hope to be marked brainliest

the answer is 21%.
