To produce a reflection, or mirror image, you need to specify a line of reflection. when mirroring objects on a plane, a line of reflection is represented by a straight line. move polygon abcd around the coordinate plane, and describe the three lines of reflection that you see.

ABCD is reflected about the x-axis to form AxBxCxDx and reflected about the y-axis to form AyByCyDy When ABCD is reflected about EF  the image is AEFBEFCEFDEF.

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)
