The equation 9 x 2 − 12 x + 4 = 0 9 x 2 − 12 x + 4 = 0 has how many different solutions?
Hatshy [7]

We have the equation:

9x^2-12x+4=0

so:

a=9\qquad b=-12\qquad c=4

and:

\Delta=b^2-4ac=(-12)^2-4\cdot9\cdot4=144-144=\boxed{0}

This equation has one solution.

The required diameter of dwarf planet is 10^{6}  m.

<h3>What is a statement?</h3>

A statement is a declarative sentence that is either true or false but not both. A statement is sometimes called a proposition. The key is that there must be no ambiguity. To be a statement, a sentence must be true or false, and it cannot be both.

Given:

The given statement is the diameter of 3 planet is

planet A= 10^{9} m= 1000000000m

planet B=10^{7} m=10000000m

planet C= 10^{8} m=100000000m

According to given question we have

A dwarf planet is discovered with a radius is 1/100 times of radius of planet C.

Radius of planet C =100000000/2=  50000000m

Radius of  dwarf planet = 1/100 times of radius of planet C.

Radius of  dwarf planet = 1/100 * 50000000m

Radius of  dwarf planet = 500000 m=5*10^{5} m

Diameter of dwarf planet =2*500000 m=1000000 m=10^{6}  m

Therefore, the required diameter of dwarf planet is 10^{6}  m.
