a light bulb in a flashlight is at the focus of its parabolic reflector,1.5 centimeters from the vertex of the reflector. write an equation for the cross section of the flashlights reflector with the focus on the positive x-axis and its vertex at the origin

Figure lmno is located at l (1, 1), m (4, 4), n (7, 1), and o (4, −2). use coordinate geometry to best classify quadrilateral lmno.

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
