We have been given that Doria swam the 100-meter backstroke in 58.329 seconds. We need to express this time in words.

We know that given time whole number part as well as decimal part.

Therefore, we can express the given time in words as:

Fifty-eight AND three hundred twenty-nine thousandth

OR

Fifty-eight POINT three hundred twenty-nine thousandth

step-by-step explanation:

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.
