Answer:

60 days

Step-by-step explanation:

Let's call h the daily dose of medication that a diabetic person should administer.

We know that:

h = 0.0005 L/day

We know that 0.03 liters is what the social institution provides.

Then we can raise the following equation:

hx = 0.03

Where x is the number of days

So:

x = \frac{0.03}{h}\\\\x = \frac{0.03}{0.0005}

x = 60 days.

After 60 days you will have to return for more doses

grin007 [14]
Hello!

A) 
<span>The mass of the air freshener A decreases by 3.2 grams each day. Define a function, f, to represent this situation.

In this function, the mass of the air freshener A (m) is the dependent variable and the days (t) and the initial amount of the air freshener A (mi) are the independent variables. If the mass decreases by a fixed amount each day, you only have to multiply this amount by the number of days:

</span>m=mi-(3,2*t)

<span>B) The mass of the air freshener B decreases by 3.2% each day. Define a function, g, to represent this situation.
</span>
This function is trickier since there isn't a fixed amount of decreasing. Instead, the rate of decreasing depends on the initial amount of the freshener (mi). You have to include this initial amount in the equation to correctly model it. This is how you do it:

m=mi-(mi* \frac{3,2}{100}*t)

Have a nice day!
