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

A total of 285 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student t

Assoli18 [71]

Lets say the number of adult tickets is x. This means the number of student tickets is 2x. So, 2x + x = 285, or 3x =285. The means x = 95. So the number of adult tickets sold is 95.

5.69÷7 you can round to nearest hundredth

pogonyaev

The answer would be .81 becuase you can't round the 1 up to 2 becuase the number in the thousandths place is not above 5.
Hope this helps!!
