Which quadratic equation models …Write and solve a quadratic equation for the situation below. Choose the answer that has both an equation that correctly models the situation as well as the correct solution for the situation. Suppose a model rocket is launched from a platform 2 ft above the ground with an initial upward velocity of 150 ft/s.The solutions to a quadratic equation of the form ax2 + bx + c = 0, where a ≠ 0 are given by the formula: x = −b ± √b2 − 4ac 2a. To use the Quadratic Formula, we substitute the values of a, b, and c from the standard form into the expression on the right side of the formula. Then we simplify the expression. The result is the pair of ...Dec 16, 2021 · A stone arch in a bridge forms a parabola described by the equation y = a(x - h)2 + k, where y is the height in feet of the arch above the water, x is the horizontal distance from the left end of the arch, a is a constant, and (h, k) is the vertex of the parabola. Image description What is the equation that describes the parabola formed by the ... 2. The equation y = 0.15x + 0.40 represents the cost of mailing a letter weighing 1 ounce or more.

Which quadratic equation models the situation correctly? h (t) = -16t^2 + 56t + 6.5 Rounded to the nearest tenth, the solutions of the equation are -0.2, 2.4 Why can you eliminate the solution of -0.2 in the context of this problem? Check all that apply. It does not make sense for time to be negative.With quadratic equations, we often obtain two solutions for the identified unknown. Although it may be the case that both are solutions to the equation, they may not be solutions to the problem. If a solution does not solve the original application, then we disregard it. Recall that consecutive odd and even integers both are separated by two units.VIDEO ANSWER: I'M going to assume you've taken a algebra course of some sort, and you know the quadratic formula already anyway, they go ahead and give away the formula that you need to do.

Important Notes on Quadratic Function: The standard form of the quadratic function is f(x) = ax 2 +bx+c where a ≠ 0. The graph of the quadratic function is in the form of a parabola. The quadratic formula is used to solve a quadratic equation ax 2 + bx + c = 0 and is given by x = [ -b ± √(b 2 - 4ac) ] / 2a. The discriminant of a quadratic ...Geometric models are useful in adding understanding in developing the quadratic formula via completing the square procedure (Norton, 2015). Barnes (1991) suggested using graphing calculators to plot quadratics with no roots, one root, or two roots and linking this to the discriminate values.…
