Athy's customer base is 2/3 residential and 1/3 business . if she has 350 residential customers, how many total customers does she have?

 She has 525 costumers.

Step-by-step explanation:

We know that the costumer base is   residential and   business. This means that:

residential customers

Let be "x" the total costumers Athy has and "y" the number of business costumers.

Then "x" must be:

Then, in order to find "y" , we need to multiply the number of residential costumers by   and divide the product by :

Substituting we get that "x" is:

  costumers

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)
