Considering the function for the remaining amount of cesium in the atmosphere, F(x) = 1000×0.5^(x/30), we have;

First part:

The area will be safe again in about 100 years time.

Second part;

The y-intercept is at the start of the measurement

Third part;

The function is a decay function

<h3>Which method can be used to evaluate the given function?</h3>

First part;

The given function for the remaining amount of cesium is presented as follows;

$F(x) = 1000 \times {0.5}^{ \frac{x}{30} }$

When 100 kg. of cesium is remaining, we have;

$100= 1000 \times {0.5}^{ \frac{x}{30} }$

Which gives;

$\frac{x}{30} = \frac{ log(0.1) }{ log(0.5) }$

$x= \frac{ log(0.1) }{ log(0.5) } \times 30 \approx 100$

Therefore, the area will be safe again in approximately 100 years.

Second part;

The y-intercept is given by the point where <em>x </em>= 0

At the y-intercept, we therefore have;

$F(0) = 1000 \times {0.5}^{ \frac{0}{30} }$

F(0) = 1000

At the y-intercept, the amount of cesium remaining, F(x) is 1,000, which is the initial amount of cesium.

The y-intercept is therefore, at the start of the measurement, where 1000 kg. is present in the atmosphere.

Third part;

The amount of cesium remaining F (x) decreases as the time, <em>x</em>, increases, the function is therefore a decay function.

Answer:

Step-by-step explanation:

<em>x</em> is greater than 12:

$x>12 \text{ or } 12$

and <em>x</em> is less than or equal to 3 times the value of y:

$12$

We can divide everything by 3:
