A parabola with its vertex at (25,18) and its axis of symmetry parallel to the y-axis passes through point (0,43). Write an equation of the parabola. Then find the value of y When z = 40.
An equation is
When = 40, y =

Determine the fraction of total interest owed. after the fourth month of a 12-month loan: the numerator is: {(n + ) + (n + ) + (n + ) + (n + )} = , and the denominator is: {(n) + (n + 1) + + (n + )} = . therefore, the fraction is numerator/denominator (to the nearest tenth) =

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1
