One endpoint of a line segment is at (−4, −2). the line is bisected by placing the midpoint of the line segment at (3, 1). what are the coordinates of the other endpoint? (−4, −6) (−0.5, −0.5) (10, 4) (9, 5)

(10, 4)

Step-by-step explanation:

The horizontal distance from (-4, -2) to the midpoint (3, 1) is 7, and the vertical distance is 3.  To find the other end point of this line segment, add 7 to the x-coordinate of the midpoint:  3+7 = 10, and add 3 to the y-coordinate of the midpoint:  1 + 3 = 4.  The coordinates of the other end of this segment are thus (10, 4) (the fourth possible answer choice).

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)

the answer is b.)
