1. Find the constant term that should be added to make the following expression a perfect-square trinomial. x^2+2x

2. Solve by completing the square.
2x^2-6x-3=0

3. Find the x-intercepts.
y=x^2-4x+4

4. Identify the axis of symmetry, create a table of values and include the axis of symmetry.
y= -x^2+3x-3

Thanks to anyone that can help!

1. A convace shaving mirror has a focal lenght of 33cm. Calculate the image position of a cologne bottle placed in front of the mirror at a distance of 93 cm. Calculate the magnification of the image. Is the image real or virtual. Is the image inverted or upright. How large is the image formed in respect to the object?

2. A pen places 11 cm from a concave spherical mirror produces a real image 13.2 from the mirror. WHat is the focal length of the mirror. WHat is the magnification of the image. If the pen is placed 27.0 cm from the mirror, what is the new position of the image? What is the magnification of the new image? Is the new image real or virtual?

1.a physics student lifts her 2kg pet rock 2.8m straight up. He then lets it drop to the ground. Use the Law of Conservation of Mechanical Energy to calculate how fast the rock will be moving (a)half way down and (b)just before it hits the ground
2.A 65kg girl is running with a speed of 2.5m/s. How much kinetic energy does she have? She grabs on to a rope which is hanging from the ceiling, and swings from the end of the rope. How high off the ground will she swing?
3.How much kinetic energy will the 80kg skier sliding down the frictionless slope have when he is 2/3 of the way down the ramp? The vertical height of the ramp is 60m.
4.A rubber ball falls from a height of 2m, bounces off the floor and goes back up to a height of 1.6m. What percentage of its initial gravitational potential energy has been lost? Where does this energy go? Has the Law of Conservation been violated?
5.How much work must be done to increase the speed of a 12kg bike ridden by a 60kg from 8.2m/s to 12.7m/s?
