Which expression is equivalent to the radical expression shown below when it is simplified?

babymother [125]

Answer:

$\sqrt{\frac{3}{64} }$ in simplified form is $\frac{\sqrt{3}}{8}$

Step-by-step explanation:

We need to solve the expression

$\sqrt{\frac{3}{64} }$

We know that $\sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}$

and 64 = 8*8

Solving we get

$=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}$

So $\sqrt{\frac{3}{64} }$ in simplified form is $\frac{\sqrt{3}}{8}$

Consider the quadratic equations

Debora [2.8K]

Consider the two functions as
<span>y1(x) =3x^2 - 5x,
y2(x) = 2x^2 - x - c

The higher the value of c, father apart the two equations will be.
They will touch when the difference, i.e. y1(x)-y2(x)=x^2-4*x+c has a discriminant of 0.
This happens when D=((-4)^2-4c)=0, or when c=4.
(a)
So when c=4, the two equations will barely touch, giving a single solution, or coincident roots.
(b)
when c is greater than 4, the two curves are farther apart, thus there will be no (real) solution.
(c)
when c<4, then the two curves will cross at more than one location, giving two distinct solutions.

It will be more obvious if you plot the two curves in a graphics calculator using c=3,4, and 5.
