N=N0e^-kt
N0 just means the amount of C-14 at time zero (when the bird dies), or the initial number of grams
Step-by-step explanation:
.57*N0 = N0*e^(-0.0001*t)
N0 cancels out
.57 =e^(-0.0001*t)
ln(.57) = -.0001*t
ln(.57) / -.0001=t
t = 5621.189
the bird's skeleton is 5621 years old

Answer: 126.48x+109.56 would be the largest possible perimeter if the area is 1000x + 750.
Step-by-step explanation: Not 100% certain of this answer.
find square root...
31.62x+27.39
that would give us 4 sides and since perimeter of rectangle is 2l+2w...
4(31.62x+27.39)=
126.48x+109.56 would be the largest possible perimeter if the area is 1000x + 750.
Answer:
He should buy the first washing machine.
50% of 520 = 260
1st washing machine 520 - 260 = 260
20% of 520 = 104
2cd washing machine 520 - 104 = 416
1st is cheaper
