A car drives 215 km east and then 45 km north. What is the magnitude of the car's displacement? Round your answer to the nearest whole number. km

220 km  

Step-by-step explanation:

Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle.  The hypotenuse is his displacement for the combination of the two segments.

    D = √(215² + 45²)

        =  √(46,225 + 2,025)

        =  √48,250  =  219.6588... km

Nearest whole number:   220 km

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
