Which of the following expressions represent the distance between 4.35 and -2 1/5 on a number line?

a. -2 1/5 - 4.35

b. 4.35 + (-2 1/5)

c. none of the above.

is means division by fractions

step-by-step explanation:

the line of

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)
