A 25 gram sample of a substance that's used
for drug research has a k-value of 0.1229.
Find the substance's half-life, in days.
Round your answer to the nearest tenth.
Enter the correct answer.
No = initial mass (at time t = 0)
N= mass at time t
k= a positive constant that depends on the
substance itself and on the units used to
t = time, in days
2(x-4) = 4(2x + 1)
2x-8 = 8x +4
subtract 2x from each side
2x-2x-8 = 8x-2x +4
-8 = 6x+4
subtract 4 from each side
-8-4 = 6x+4-4
-12 = 6x
divide by 6
-12/6 = 6x/6
y = (x+5)(x+2)
we are given the following the quadratic function and we are to rewrite it in intercept or factored form:
we can factorize the given quadratic function such that when multiplied, the factors give a product of 10 and when added, they give a result of 7.
therefore, the factored form of the given function is y = (x+5)(x+2).
