Kyle and Keion balanced on a seesaw. Kyle's weight is 500 N and Keion weight is 300 N. The seesaw is made of a uniform plank of weight 800 N which is 4 m
long, pivoted at its centre.
By taking moments about the pivot, calculate the distance, that Keion must sit
from the pivot to balance the plank if Kyle sits I m from one end of the plank.

Write the equation for the parabola that has x− intercepts (−2,0) and (4,0) and y− intercept (0,4).

Television sizes are based on the length of the diagonal of the television's rectangular screen. so, for example, a 70-inch television is a television having a diagonal screen length of 70 inches. if a 70 inch television's diagonal forms a 29°angle with the base of the screen, what is the vertical height (1) of the screen to the nearest inch? 70 inhin
