Acircle is graphed on a coordinate grid and then reflected across the y-axis. if the center of the original circle was located at (x, y), which ordered pair represents the center of the new circle after the transformation?
a) (x, y)
b) (x, −y)
c) (−x, y)
d) (−x, −y)

This one is pretty easy. You don't even need to write the circles. To figure this one out, draw a graph and plot a point in the first quadrant. This is where x and y are both positive. Then reflect the point across the y- axis. It should look like the picture I drew. Now ask yourself, "Are the x and y positive, or negative? Which one is positive, and which one is negative?"

Since the reflected point is in the 2nd quadrant. The x is negative and the y is positive, so it looks like:

(-x, y)

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)
