A married couple has $200,000 saved for retirement. They want to live on 65% of their $90,000 annual Income
The amount of money the couple will live on annually in retirement is

The additional amount of principal
needed for retirement is $1,462,500 $1,062,500 $1,262,500

The answer is 12, for the points

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
