Answer:
x² + y² = 25
Step-by-step explanation:
The standard form of a circle is (x - h)² + (y - k)² = r² where (h, k) is the center point and r is the radius. In this case, the center is the origin which has coordinates of (0, 0) so h = 0 and k = 0. We know that the radius is 5 so r = 5. Therefore, after plugging in the values of h, k, and r, we get that the answer is x² + y² = 25.
The correct graph for the given sets of equation is given attached below.
Equation no 2 gives the perfect solution to the graph.
<h3>What is a parabola?</h3>
A parabola, is cross section cut out of the cone and represented by an equation 
Clearly, by property of the parabola, the curve of parabola should symmetric to its axis. From this property set of Equation (2) i.e. downward opening parabola increasing from negative 2 comma negative 3 to a maximum at 0 comma 1 and then decreasing through the point 2 comma negative 3 Holds the property of the parabola
Thus, the required solution for the sets of equation (2) is given in the attachment.

Answer:
the angle Ф is 63.9 degrees.
Step-by-step explanation:
A right triangle describes this situation. The height of the triangle is 45 ft and the base is 22 ft. The ratio height / base is the tangent of the angle of elevation and is tan Ф. We want to find the angle Ф:
opp
tan Ф = ---------- = 45 / 22 = 2.045.
adj
Using the inverse tangent function on a calculator, we find that the angle Ф is 63.9 degrees.
