To convert 42.3 dekameters to kilometers, decide if you should multiply or divide by a power of 10.

1 dekameter is larger than kilometer so divide by power of 10

42.3 decameters  = 0.423 kilometers so the power of 10 is 10^2

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:
