Mixed # x denominator + numerator = imp. Fraction
28 x 14 = 392 + 11 = 203
203/14 = 29/2 = 14.5
Answer:
y=1x+3
3 is where the line hits the y axis
<u>1</u>
1 is how munch it rises/goes to the side
F=ar^t if the half-life is 96 years...
.5=r^96
ln(.5)=96lnr
ln(.5)/96=lnr
r=e^((ln.5)/96)
f=800e^(336(ln.5)/96)
f=70.71
So about 71mg will remain after 336 years.
Half of the circumference:
18.84/2 which would leave you with 9.42 feet.
