Chromium 51 is a radioactive substance used in medicine.
It has a 1/2 life of 28 days.
The equation for its exponential decay model is
28
y=a(.5)
If 10 mg is ingested by a patient, how many days
before only 8 mg is still emitting radiation?
Solve. 8 = 10(.5)
fort.
Use the base change formula to solve your logarithm.

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
