What is the value of m, if the equation my2+2y−4=0 has exactly one root?

stich3 [128]

Answer:

$m=\frac{-1}{4}$

Step-by-step explanation:

A quadratic equation has one root if the discriminant is 0.

That is we need $b^2-4ac=0$ for this particular question.

Compare the following to find $a,b, \text{ and } c$ :

$ax^2+bx+c=0$

$my^2+2y-4=0$

The variable $x$ is representative of the variable $y$ here.

$a=m$

$b=2$

$c=-4$

Plug in into $b^2-4ac=0$ :

$(2)^2-4(m)(-4)=0$

$4+16m=0$

Subtract 4 on both sides:

$16m=-4$

Divide both sides by 16:

$m=\frac{-4}{16}$

Reduce:

$m=\frac{-1}{4}$

F=P(1/2)^(t/h)
F=future amount
P=present amount
t=time elapsed
h=legnth of half life

P=96
t=2
h=1
F=96(1/2)^(2/1)
F=96(1/2)^2
F=96(1/4)
F=96/4
F=24 grams

grow by 35%
compound interest
F=P(1+rate)^time
F=95000(1+0.35)^10
F=95000(1.35)^10
F=95000(20.106555868618)
F=1910122.9075187
