If you deposit P dollars at rate r, in decimal form, subject to compound interest, then the amount, A, of money in the account after t years is given by

                                                     

The amount A is called the account's future value and the principal P is called its present value.

From the information given we know that $500 is the present value,  6% is the rate, and we want to find how long will it take for Suzy to earn at least $95, this means when the future value is $595.

Applying the above formula and solving for t we get that:

Write the vertex form of the equation of the parabola which has a vertex of (0,0) and contains the point (1,2). A. Y=2x^2. B. Y=
Aleonysh [2.5K]
General equation of parabola:  y-k = a(x-h)^2

Here the vertex is at (0,0), so we have y-0 = a(x-0)^2, or y = ax^2

All we have to do now is to find the value of the coefficient a.

(1,2) is on the curve.  Therefore, 2 = a(1)^2, or 2 = a(1), or a = 2.

The equation of this parabola is y = 2x^2.
