An applicable equation of a vertical parabola in vertex form is:
y-k = a(x-h)^2
Let x=2, y=4, h=-1 and k=-1, where (h,k) is the vertex. Then,
4-(-1) = a(2-[-1])^2, which becomes 5 = a(9). Therefore, a = 5/9, and the
equation of the parabola is
y+1 = (5/9)(x+1)
For this case we have the following type of equations:
Quadratic equation:

Linear equation:

We observe that when equating the equations we have:

Rewriting we have:

We obtain a polynomial of second degree, therefore, the maximum number of solutions that we can obtain is 2.

Answer:
5.5%
Step-by-step explanation:
To solve this problem we can use a modified version of the simple interest formula which is shown below:

<em>I = interest amount</em>
<em>P = principal amount</em>
<em>t = time (years)</em>
<em />
The first step is to find the interest gained from the investment.

Next, plug in the values into the equation:
Multiply the bottom values
Divide the values

The last step is to convert 0.055 into a percent:

The interest rate is 5.5%
