3. The diagram shows a ball of mass 5kg released from a height of 3.5m from the Earth's surface. Calculate the gravitational potential energy possessed by the ball before it is released. (in Joule units/write numbers only) *

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

Hardest math question of all time can you solve the equation. check for extraneous solutions.9∣9-8x∣ = 2x+3

Need same math paper but the back now i hope your able to read it cleary i need with hw
