Lighthill (1952) used the same idea to develop his acoustic analogy in which the equations of fluid motion, expressing conservation of mass and momentum, are combined to yield a linear wave equation with nonlinear forcing terms. In both cases, the ‘base flow’ is a uniform fluid at rest. What doesRead More →
We know that quadratic equation has two equal roots only when the value of discriminant is equal to zero. We know that two roots of quadratic equation are equal only if discriminant is equal to zero. What is the equation with equal roots? – If b2 – 4ac = 0Read More →
The Quadratic Formula uses the “a”, “b”, and “c” from “ax2 + bx + c”, where “a”, “b”, and “c” are just numbers; they are the “numerical coefficients” of the quadratic equation they’ve given you to solve. What are examples of quadratic equations? Examples of quadratic equations in other formsRead More →
To determine if an ordered pair is a solution to a system of two equations, we substitute the values of the variables into each equation. If the ordered pair makes both equations true, it is a solution to the system. Which ordered pair is not a solution? Note: To seeRead More →
Step 1 : Split the first term 4x² as the multiple of two same terms. That us , 4x² = 2x (2x) Step 2 : Multiply the numerator by 2. Step 3 : Divide the new term that is 4x by the second term of the given quadratic equation. 4x/(-4x)Read More →
The y-intercept formula says that the y-intercept of a function y = f(x) is obtained by substituting x = 0 in it. Using this, the y-intercept of a graph is the point on the graph whose x-coordinate is 0. i.e., just look for the point where the graph intersects theRead More →
*VC is the maximum volume expelled by a forceful effort after maximal inspiration. (Also, VC= IC+ERV. How is Erv calculated? Estimated recovery value (ERV) is the projected value of an asset that can be recovered in the event of a liquidation or wind down. The calculation for estimated recovery valueRead More →
