anyone know this giving brainliest whoever is correct no lie worth 100 points and it better be right if it is bogus then i am reporting you

see below

Step-by-step explanation:

The coordinates are (x,y)  The top right is the 1st quadrant and it is positive, positive (+,+).  The top left is the second quadrant and it is negative, positive (-,+).  The bottom left is the third quadrant and it is negative, negative (-,-).  And the bottom right is the fourth quadrant and it is postive negative (+,-).

Where the axis meet is (0,0)  and is called the origin.  Going left and right is the x axis (the first coordinate).  To the right is positive and to the left is negative.  Going up and down is the y axis ( the second coordinate).  Up is positive and down is negative.

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)
