If the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola, find an equation for the parabola. Write your answer in the form () = ( − ℎ)2 + .

Step-by-step explanation:

W have been given that the vertex of a parabola is at (2, 3) and the point (0, -1) is also on the parabola. We are asked to find the equation of parabola in the form .  

We know that vertex form of parabola in form , where (h,k) in vertex of parabola.  

Upon substituting coordinates of vertex, we will get:

To find the value of a, we will substitute coordinates of point (0, -1) as:

Therefore, our required equation would be .

A = $992.00

(I = A - P = $192.00)

Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.

Solving our equation:
A = 800(1 + (0.04 × 6)) = 992 
A = $992.00

The total amount accrued, principal plus interest, from simple interest on a principal of $800.00 at a rate of 4% per year for 6 years is $992.00.
