Given the zeros of a polynomial, you can very easily write it -- first in its factored form and then in the standard form. Subtract the first zero from x and enclose it in parentheses. This is the first factor. For example if a polynomial has a zero that is -1, the corresponding factor is x - (-1) = x + 1.
Let the initial mass be represented by . Therefore, .
Let the final mass (or present mass be represented by . Therefore, .
Now, we are given that the rate of decay is 8% or 0.008 per day. Therefore, the amount of substance remaining after each day will be . Let us represent this by .
Please note that the equation guiding such decays is always given by:
, where t is the time.
Thus, the above equation will give in our case:
Taking natural logarithm on both sides we get:
Therefore,
days<9 days
Thus, in 9 days there will be further decay and the sample left will definitely be less than 115 milligrams.
The only option which matches this reality is Option C. Therefore, Option C is the correct answer.
It seems that 1 might be A or B and 2 might be C or D. Hope this helps. :-)
Answer:
D
Step-by-step explanation:
Organ for mental process that creates fresh and original poem or drama performs similar functions as the organ which process and elaborate scientific discoveries.
-2x
6 - 4 = 2
BOTH NUMBERS HAVE VARIABLE OF X SO THE X WILL GO ON THE 2 ALSO
6x - 4x = 2x
