The answer is 3.125%.

The relation between number of half-lives (n) and amount of sample that remained (x) can be expressed as:
(1/2)^{n} =x

It is given:
n = 5

To find x, we will change n in the equation with five:

<span>(1/2)^{n} =x
</span>⇒ <span>(1/2)^{5} =x
</span>⇒ <span>0.5^{5} =x
</span>⇒ x=0.03125 =  \frac{3.125}{100} = 3.125%

Therefore, 3.125% of a radioactive species <span>would be found as daughter material after five half-lives.</span>

The area of the given rectangle is of the standard form option 1.2x^{2} + 3x - 20.

Step-by-step explanation:

Step 1:

The parameters needed to determine the area of a rectangle are the base length and the width.

The base length of this rectangle is 2x-5 units while its width is x+4 units.

The area of a rectangle is determined by multiplying the base length with the width.

Step 2:

The area of the rectangle = (length)(width).

Here length is 2x-5 units and the width is x+4 units.

The area of the rectangle= (2x-5)(x+4) = 2x^{2} + 8x -5x-20 = 2x^{2} + 3x - 20.

So the area of the given rectangle is of the standard form 2x^{2} + 3x - 20 which is the first option.
