<h3>
Answer: x^2 + 6</h3>
Work Shown:
(f o g)(x) = f(g(x))
f(x) = x + 7
f( g(x) ) = g(x) + 7 ... replace every x with g(x)
f( g(x) ) = x^2-1 + 7 .... plug in g(x) = x^2-1
f( g(x) ) = x^2 + 6
(f o g)(x) = x^2 + 6
Answer:
o
Step-by-step explanation:
Answer: 4/6 or 2/3
Step-by-step explanation:
Half of the dice has even numbers and the other has odds so because of that it already gives you a 3/6 or 1/2 chance of getting an even. And the one for getting would be a 1/6. But because we already have the evens for 3/6 we can then add the 1/6 to get 4/6 or 2/3
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.
