Answer: 8
Step-by-step explanation:
Answer:
Commutative property of addition of rational numbers: Two rational numbers can be added in any order. Thus for any two rational numbers a/b and c/d, we have. (a/b + c/d) = (c/d + a/b)
Step-by-step explanation:
the x-intercept of this function is (-1,0)
Answer:
No, x can't equal zero.
Step-by-step explanation:
substitute x for zero. now the equation says 4+0+2>8
4+2 is 6 so 6 < 8. 6 is less than 8 not greater, therefore x can't be zero
Answer:
Half life of the radioactive element is 5 days.
Step-by-step explanation:
Formula to get the final amount after the radioactive decay in 't' days,
Here = Initial amount
λ = Decay constant
t = duration of decay
= Final amount
0.01 =
ln(0.01) =
-4.6052 = -34λ
λ = 0.13544
Since, λ =
= 5.11
≈ 5 days
Therefore, half life of the radioactive element is 5 days.
