Afamily uses 12,986.64 swiss francs per year to pay a mortgage that requires us dollars. approximately how much, in us dollars, does the family spend per month on the mortgage? 1 us dollar = 0.9019 swiss francs 1 swiss franc = 1.11 us dollar

$1201.26 per month.

Step-by-step explanation:

A family uses 12986.64 Swiss francs per year to pay a mortgage that requires US dollars.

We have to find the dollars, family spend per month on mortgage.

In this question we will convert the amount given in Swiss francs into US dollars.

Then we will calculate per month expenditure on the mortgage by dividing US dollars by 12 months.

Since 1 Swiss franc = 1.11 US dollar

12986.64 Swiss franc = 12986.64×1.11

                                                      = 14415.1704 US dollar

Now per month payment of the mortgage =

                                                                      = $1201.26

Therefore, family will pay $1201.26 on mortgage in a month

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.
