When the equation is of the form
... ax² +bx +c = 0
the discriminant is
... d = b² -4ac
Here, your equation is in the appropriate form, so we can identify
... a = -1, b = 4, c = -2
and calculate the discriminant as
... d = 4² - 4(-1)(-2) = 16 - 8 = 8
The discriminant is 8.
<h3><u>Answer;</u></h3>
= 3,391 viruses
<h3><u>
Explanation;</u></h3>
- The population density is 1.2 viruses per square millimeter.
- This means, each square millimeter is occupied by a population of 1.2 viruses.
Therefore; for an area of 2,826 square millimeters, there will be;
= 2,826 multiplied by 1.2 viruses
= 2,826 × 1.2
= 3391.2 viruses,
and since we can have a fraction or decimal virus then the population would be <u>3391 viruses</u>
