Keep track of each attempt (don't erase your thinking, even though it was wrong!) and record what you learned and how
your strategy will change:

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:

question 1: step-by-step explanation:

1/4 of 84 = 84÷4= 21

8.3 and the 3 is repeating

hope this .
