The time period, T, of a simple pendulum is directly proportional to the square root of the length, d, of the pendulum. When d=6, T=5

Find the value of T when d=3

Input note: give your answer correct to 2 decimal place.

Jack has a rectangular piece of land, the area of which is represented by a1 = 9.5l. his brother has a different rectangular piece of land, the area of which is represented by a2 = l(14 − l). let a represent the area in square meters and l represent the length in meters of the pieces of land. the two equations plotted on a graph meet at a point as shown in the image
