B.1.258, hope I helped! :)
Answer:
(5x + 6) (x + 7)
Step By Step Explanation:
Use the sum form to the product.
5
21
3*7times 7+7=14+7 =21
21 0 3-3=0
21/1 0/1 butterfly method 21*1=21 0*1 =1
21*1
=21 hope this helps
m^2 + 12m + 35
We can factor using the sum-product, when the sum of 2 numbers is 12 and the product of those 2 numbers is 35.
7+5 = 12
7 x 5 = 35
So we have the numbers 7 and 5.
m^2 + 12m + 35 = (m+7)(m+5)
The decay constant is i 0.1155, and there would be 16 mg left after 24 hours.
The relationship between the half-life, T₀.₅, and the decay constant, λ, is given by
T₀.₅ = 0.693/λ.
Solving for λ, we will multiply both sides by λ first:
(T₀.₅)(λ) = 0.693
Since we know the half life is 6 hours, this gives us:
6λ = 0.693
Dividing by 6, we have
λ = 0.693/6 = 0.1155.
The decay constant will be k in our decay formula, and N₀, the original amount of substance, is 250:
N(24) = 250e^(-0.1155*24) = 15.6 ≈ 16
