Iodine-125 has a half-life of about 60 days.
Murljashka [212]

62.5 mg sample will remain after 240 days

Step-by-step explanation:

Given

Half-life = T =  60 days

The formula for calculating the quantity after n half lives is given by:

N = N_0(\frac{1}{2})^n

Here

N is the final amount

N_0 is the initial amount

n is the number of half lives passed

The number of half lives are calculated by dividing the time for which the remaining quantity has to be found by half life

The quantity has to be calculated for 240 days so,

n = \frac{240}{60}\\n = 4

Given

N_0 = 1000\ mg

Putting the values in the formula

N = 1000 (\frac{1}{2})^4\\=1000 * \frac{1}{16}\\=\frac{1000}{16}\\=62.5\ mg

Hence,

62.5 mg sample will remain after 240 days

Keywords: Half-life, sample

Which of the following shows the graph of y = 4x 3? on a coordinate plane, an exponential function starts at y = 3 in quadrant 2
ZanzabumX [31]

The graph of the linear equation y = 4x + 3 can be seen at the end of the answer.

<h3>How to find the graph of the given line?</h3>

Here we have the linear equation:

y = 4x + 3.

To graph it, we need to find two points that belong to the line, to do that, we evaluate in two different values of x. I will use x = 0 and x = 2.

When x = 0.

y = 4*0 + 3 = 3

So we have the point (0, 3).

When x = 2:

y = 4*2 + 3 = 8 + 3 = 11

So we have the point (2, 11)

Now we just need to graph these two points and connect them with a line. The graph of the linear equation is the one you can see below.
