Find the value of k by<br>quardractic equation two real and equal roots<br>5x - 2kx +20=0

kotegsom [21]

Answer:

k = +10 or -10

Step-by-step explanation:

It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.

$= > {b}^{2} - 4ac = 0$

$= > {( - 2k)}^{2} - 4 \times 5 \times 20 = 0$

$= > 4 {k}^{2} - 400 = 0$

$= > 4( {k}^{2} - 100) = 0$

$= > {k}^{2} - 100 = 0$

$= > k = \sqrt{100} = + 10 \: or \: - 10$

Savatey [412]

This is the concept of algebra, to solve the question we proceed as follows;
the current number of women is:
1/4*20=5 women
the percentage of women is:
1/4*100=25%
therefore for the team to have 40% women, the number of women should be:
40/25*5
=8 women
The answer is 8 women
