For #1-4. Solve every quadratic equation using the quadratic formula being sure to: Identify o, b. and c. Substitute o, b, and G into the formula [without simplifying}. Simplify, showing work. Express exact answers for each solution. If the solution con also be approximated, find the approximate answer rounded to the nearest hundredth. 1. 4x2+8x2120 2. 35:2291 3. x2+36=0 4.412311520 For #5-7, Use the discriminant to determine hot-i.r many solutions you would expect the following quadratic equations to have. Then solve them using the quadratic function. still using the guidelines for #14, to see if you were correct. 5. x2+6x+5320 For #5-7, Use the discriminant to determine howr many solutions you would expect the following quadratic equations to have. Then solve them using the quadratic function, still using the guidelines for #1-4, to see if you were correct. 5.x2+6.1'+53=0 6. 3I292 2x 14: -1-:c+:c2 B. You were given a quadratic equation that models the height h and time [for an object being thrown {or launched]. When you solved the equation to find the time when the object hits the ground, you got solutions of r = 4 seconds and t = 5 seconds. What do those solutions mean in terms of the problem? Do both solutions make sense? 9. An object is launched horizontally at 19.6 mfs {meters per second} from a 58.8 meter tall platform. The equation for the object's height h {in meters} at time t {in seconds} after launch is modeled by the equation Mt) = 4.9:: + 19.6: + 58.8. Find out when the object will strike the ground? (Hint. use the quadratic formula to find [when the height hit} is equal to 0.} 10. A ball is launched toward the ceiling, straight up, at a velocity of 48 feet per second. The equation h(t) = - 16t + 48t represents the height, in feet, above the ground after t seconds. How long did it take the ball to hit the ground
