Which quadratic equation models the situation correctly

The parabola formed by the arch is described by y ≈ -0.071·(x - 13)² + 12. The reason why the above equation that describes the parabola formed by the arc is correct is given as follows:. The given parameter of the stone arch bridge are;. The equation of the parabola that represents the stone arch is y = a·(x - h)² + k. The height of the arch above water = y in feet.

The rate of change, or slope, is -$250 per month. We can then use the slope-intercept form and the given information to develop a linear model. f ( x) = m x + b = − 250 x + 1000. Now we can set the function equal to 0, and solve for x to find the x-intercept. 0 = − 250 + 1000 1000 = 250 x 4 = x x = 4.A General Note: Forms of Quadratic Functions. A quadratic function is a function of degree two. The graph of a quadratic function is a parabola. The general form of a quadratic function is f (x) = ax2 +bx+c f ( x) = a x 2 + b x + c where a, b, and c are real numbers and a≠ 0 a ≠ 0. The standard form of a quadratic function is f (x)= a(x−h ...

So, let's just apply the quadratic formula. The quadratic formula will tell us that the solutions-- the q's that satisfy this equation-- q will be equal to negative b. b is 2. Plus or minus the square root of b squared, of 2 squared, minus 4 times a times negative 7 times c, which is 9. And all of that over 2a.1.

The vertex is easy to find when the formula is given in vertex form. It is the point (h,k). If the formula is in standard form, then the x-coordinate of the vertex is found by x = −b 2a. To find the y-coordinate of the point, plug in this x-value into the formula. charger scat pack accessories After doing so, solve for x x as usual. The final answers are {x_1} = 1 x1 = 1 and {x_2} = - {2 \over 3} x2 = -32. Example 3: Solve the quadratic equation below using the Quadratic Formula. This quadratic equation looks like a "mess".
