The cost c (in dollars) of making n feet of cabinet is represented by c = 18n + 45.how many feet of cabinet are made when cost is $144?

The amount of board is 5.5 feet because 18*5.5=99 and 144-45 is 99.

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

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)
