Mathematics
1 answer:

3 0

Answer:

(a + c) + 7

Step-by-step explanation:

Because the only type of math in this expression is addition, whatever way you write it (keeping only plus signs), the answer will be the same. So,              a + (c + 7) is equal to (a + c) + 7.

I hope this helps!

Carlos has taken an initial dose of a prescription medication.
Marat540 [252]

Answer:

3.48 hours

Step-by-step explanation:

The equation is:

M(t)=20 e^{-0.86t}

Where

M(t) is the amount of medication remaining in mg

t is the time it takes, in hours

The questions asks HOW LONG it will take to make the remaining medication to 1 milligrams (1 mg)??

We have to substitute M(t) with "1" and find the corresponding value of "t". We will use natural log to solve this. Shown below:

M(t)=20e^{-0.86t}\\1=20e^{-0.86t}\\0.05=e^{-0.86t}\\Ln(0.05)=Ln(e^{-0.86t})\\Ln(0.05)=(-0.86t)Ln(e)\\t=\frac{Ln(0.05)}{-0.86}\\t=3.48

<u>Note: </u> Ln(e) = 1

This means, the amount of time it will take is about 3.48 hours

The probability of something happening is the number of chances / total number

The probability would be 2/6, which can be reduced to 1/3
