<u>Answer-</u>

<u>Solution-</u>
The equation for time period of a simple pendulum is given by,

Where,
T = Time period,
L = Length of the rod,
g = Acceleration due to gravity.
Frequency (f) of the pendulum is the reciprocal of its period, i.e

Putting the values,




Answer:

Step-by-step explanation:
Given the equation of parabola

This is the vertex form of the parabola equation. Hence, the vertex of the parabola is at point 
This parabole goes downwards in y-direction (the leading coefficient -5 is negative)
<u>The axis of symmetry</u> of parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
Thus, the equation of the axis of symmetry is

Im not sure if this is right but it is 1026
25500-10900=40x
14600=40x
x=365
