Step-by-step explanation:
<u>Functions
</u>
The problem describes a function that expresses the concentration of an antibiotic in mg/dl vs time in hours as:
We need to find the first value of t such that
It means that
Operating with the inequality
Rearranging and dividing by 2, we have a polynomial inequality:
Factoring
There are two possible values for t, both valids because they are positive
We need to find the first value, i.e.
Now for the graphic method, we plot the graph for the function and a horizontal line at c=4 to find the values of t.
The graph is shown in the image provided below. We can see both values where the funcion and C=4 intersect. Both values coincide with the previously analitically found values
What you have to do is multiply each of the sides so you have 80, 60, and 48.
Add those up to get 188. Then multiply this by 2 and you get 376.
Your answer is D. (376)
P.S if this helped you out, please give me brainliest if you don't mind. I am only a few more from leveling up :D
Step-by-step explanation:
ax=axn to rewrite
3√27x12 as (27x12)1/3
to rewrite
3√(3x^4)3
Pull terms out from under the radical, assuming real numbers.
3X^4
All you have to do is understand what fraction it is and reduce it. So first you have to figure out what the word reduce means and the word means another to figuring it out in its lowest terms and for example, your fraction 2/24 can be reduced in its simplest terms 1/12 and the way i did that was that i'd had to divide both the numerator and denominator by 2 because I know that both the numerator and denominator are divisible by 2 and so if you divide you get 1/16 and that's how you reduce fractions and so follow this procedure and you'll get everything correct.
