Give the coordinates for the image of r (0, -5) e (4, -3) c (6, -5) t (2, -7) when it is reflected across the line y = x.

Below.

Step-by-step explanation:

The x and y coordinates flip with this reflection e, g   (2, 1) goes to (1, 2).

So  R (0, -5) ---> R' (-5, 0).

     E (4, -3) ---> E' (-3, 4).

     C (6, -5) ---> C' (-5, 6).

    T (2, -7) ---> T' (-7, 2).

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)

answer: 5100 just subtract
