Solve the equation by completing the square. Round to the nearest hundredth if necessary.

x^2+3x-5=0

1.66, 2.69

1.05, –4.05

1.19, –4.19

–8.75, 5.75

1•19,-4•19

Step-by-step explanation:

x²+3x-5=0

x²+3x=0+5

x²+3x/2=5

x²+(3x/2)²=5+9/2

√(x+3/2)²=19/2

x=19/2-3/2,19/2+3/2

x=1.19,-4.19

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
