4m references the 4 bags of marbles and the m marbles in each bag. + 3 references the extra 3 marbles.
The exponent value would be 3
Answer:
Step-by-step explanation:
let x be the side length of the small square
x² + (x + 3)² = 89
x² + (x² + 6x + 9) = 89
2x² + 6x - 80 = 0
x² + 3x - 40 = 0
(x + 8)(x - 5) = 0
so x = -8 or x = 5
A negative length does not make sense
small square side 5 inch
5 + 3 = 8
large square side 8 inch
For this problem, we use the formula for
radioactive decay which is expressed as follows:<span>
An = Aoe^-kt
where An is the amount left after time t, Ao is
the initial amount and k is a constant.
We calculate as follows:
An = Aoe^-kt
0.5 = e^-k(9000)
k = 7.7 x 10^-5
An = Aoe^-kt
.10 = e^-</span>7.7 x 10^-5<span>(t)
t = 29903.7 years</span>
