I can not use my calculator because my PC is going too slow. But what you do is add up 4+3+4+5+6+6+8+4 and divide it all by 8 (8 being the total numbers in all. That is how you solve all means.)

What us the value of the discriminant of the quadratic equation -2^2=-8x+8 and what does its value mean about the number of a re

svlad2 [7]

ANSWER

The discriminant is zero.

The given equation has one real root.

EXPLANATION

The given quadratic equation is:

$- 2 {x}^{2} = - 8x + 8$

We rewrite this in the form;

$a {x}^{2} + bx + c = 0$

$- 2 {x}^{2} + 8x - 8 = 0$

This means that,

a=-2, b= 8, c=-8

The discriminant is given by;

D=b² - 4ac

That is:

$D = {8}^{2} - 4( - 2)( - 8)$

$D = 64 - 64 = 0$

Therefore the discriminant is zero.

This tells us that the quadratic equation has one real root.

In order words, the given quadratic equation has a repeated real root.

A medical researcher has two petri dishes containing viruses. Dish A has a population density of 1.2 viruses per square millimet

Lyrx [107]

<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>
