Express the given percent as a decimal.1/2% (round to five decimal places as needed.)

The required expression is

Step-by-step explanation:

Given : Percentage

To find : Express the given percent as a decimal ?

Solution :

To convert percentage into decimal,

To remove percentage sign we divide the given number by 100.

So,

Remove percentage,

Now, Put decimal after three digit

As we have to round it to five decimal places,

Therefore, The required expression is

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
