Graph x^3 - 3x^2 + 2 = 0.1 - x What are the solutions of the equation?

liq [111]

Answer:

$x=-0.6,x=1.52,x=2.08$

Step-by-step explanation:

Let $f(x)=x^3-3x^2+2$ .

and

$g(x)=0.1-x$

The graph of the two equations are shown in the attachment.

The points where the two graphs intersected are: $(-0.6,0.7),(1.52,-1.42),(2.08,-1.98)$

The x-coordinates of the intersection points are the solutions to $x^3-3x^2+2=0.1-x$ .

Therefore the solutions are: $x=-0.6,x=1.52,x=2.08$

How do you solve this?

blondinia [14]

Answer:

≈ 3.6 x 10^1

Step-by-step explanation:

= (6.05 x 3.05) x 10^(5+4) / (4.27 x 1.2) x 10^(4+4)

= 18.4525 x 10^9 / 5.124 x 10^8

= (18.4525 / 5.124) x 10^(9-8)

≈ 3.6 x 10^1
