All you have to do is plug in the given values into the given equation and evaluate.
The expression is,

But we have to analyze the problem carefully. This is a natural phenomenon that can be modelled by a decay function. The reason is that, after every hour we expect the medicine in the blood to keep reducing.
Therefore we use the decay function rather. This is given by,

where,


and

On substitution, we obtain;


Now, we take our calculators and look for the constant

,then type e raised to exponent of -1.4. If you are using a scientific or programmable calculator you will find this constant as a secondary function. Remember it is the base of the Natural logarithm.
If everything goes well, you should obtain;

This implies that,

Therefore after 10 hours 24.66 mg of the medicine will still remain in the system.

Hello! Remember you have to write clear questions in order to get good and exact answers. Here I'll assume the data given in a comment above. So:

We know that the area (A) of any rectangle is given by:

Answer:
Y = -1/2X + 2
Step-by-step explanation:
Dilation involves changing the size of a shape.
The scale factor of dilation is 2
<h3>How to determine the scale factor</h3>
From the figure, we have the following highlights
- Both pentagons are regular polygons
- The side lengths of the second polygon are twice the side lengths of the first
The second highlight above means that:
The scale factor of dilation is 2
