<h2>y is 28.125 when x = 25</h2>
<em><u>Solution:</u></em>
Given that,
y is inversely proportional to the square root of x
Therefore,
----------- eqn 1
Where, c is constant of propotionality
y = 45 when x = 64
Substitute in eqn 1
What is y when x = 25?
Substitute x = 25 and c = 5.625 in eqn 1
Thus y is 28.125 when x = 25
Using the discriminant of a quadratic equation, it is found that the quadratic equation would have one repeated solution for m = -3.
<h3>What is the quadratic equation?</h3>
The quadratic equation is given as follows:
mx² + 12x - 12.
<h3>What is the discriminant of a quadratic equation and how does it influence the solutions?</h3>
A quadratic equation is modeled by:
The discriminant is:
The solutions are as follows:
- If , it has 2 real solutions.
- If , it has 1 real solutions.
- If , it has 2 complex solutions.
For this problem, the coefficients are:
a = m, b = 12, c = -12.
Hence the discriminant is:
b² - 4ac = 144 + 48m.
We want it to be of 0, hence:
144 + 48m = 0
m = -144/48
m = -3.
