Answer:

T = 4.0 s

Step-by-step explanation:

The period of a simple pendulum is given by

period = 2\pi \sqrt{ \frac{l}{g} }

where l = length of the pendulum

= 4 m

g = acceleration due to gravity

= 9.8 m/s^2

period = 2\pi \sqrt{ \frac{(4 \: m)}{(9.8 \:  \frac{m}{ {s}^{2} } )} }  = 4.0 \: s

The general form of an parabola is 4y2 + 40y + 3x + 103 = 0
valentinak56 [21]

The standard form of the parabola is   x = -4/3y² -40/3y -103/3

What is parabola?

A parabola is an approximately U-shaped, mirror-symmetrical planar curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves. One way to describe a parabola is with a point and a line.

 x = -4/3(y +5)² -1

Solve for x.

 x = (4y² +40y +103)/(-3)

 x = -4/3y² -40/3y -103/3 . . . . 'standard form' in the US

__

Taking our clues from the graph*, we can write the vertex form equation as ...

 x = -4/3(y +5)² -1 . . . . . . 'standard form' in other places

____

* The vertex is (-1, -5), so for some leading coefficient, the equation will be ...

 x = a(y -(-5))² +(-1) = a(y +5)² -1

The value of 'a' is the scale factor. Here, that is the difference between the parabola value (x = -2 1/3) and the vertex value (x = -1) one unit away from the vertex.
