Doreen walks 3.46 kilometers on the treadmill. How many meters does Doreen walk?

3460 m

Step-by-step explanation:

There are 1000 meters in a kilometer and since Doreen walks 3.46 km, she must walk 3460 m.

3.46 x 1000 = 3460

3.46 km = 3.46*1000m = 3460 m

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)
