find the intersection points of that equation and this 5=\left(x-5.3\right)^{2}+\left(y-38.3\right)^{2}

To find the intersection points of the parabola \( y = -1(x - 5.7)^2 + 44 \) and the circle \( 5 = (x - 5.3)^2 + (y - 38.3)^2 \), we need to solve the system of equations by substituting the equation of the parabola into the equation of the circle.

### 1. Equations of the Parabola and Circle:

- Parabola: \( y = -1(x - 5.7)^2 + 44 \)
- Circle: \( 5 = (x - 5.3)^2 + (y - 38.3)^2 \)

### 2. Substituting the Parabola Equation into the Circle Equation:

Substitute \( y = -1(x - 5.7)^2 + 44 \) into the circle equation:

\[
5 = (x - 5.3)^2 + \left(-1(x - 5.7)^2 + 44 - 38.3\right)^2
\]

Simplify the equation:

\[
5 = (x - 5.3)^2 + \left(-1(x - 5.7)^2 + 5.7\right)^2
\]

This is now a single equation in \(x\). We can solve this equation to find the intersection points. 

I'll proceed to solve this equation for \(x\).The solutions for \(x\) are approximately:

1. \( x_1 = 3.172 \)
2. \( x_2 = 3.654 \)

There are also two complex solutions \(x_3\) and \(x_4\), which are not relevant for finding real intersection points.

### 3. Find the Corresponding \(y\) Values:

Now, let's substitute these real \(x\) values back into the equation of the parabola to find the corresponding \(y\) values.The corresponding \(y\) values for the real \(x\) solutions are:

1. When \( x_1 = 3.172 \), \( y_1 = 37.612 \)
2. When \( x_2 = 3.654 \), \( y_2 = 39.813 \)

### Intersection Points:
The real intersection points between the parabola and the circle are approximately:

1. \((3.172, 37.612)\)
2. \((3.654, 39.813)\)
