What are real solutions of an equation? How To Solve Them? The “solutions” to the Quadratic Equation are where it is equal to zero. There are usually 2 solutions (as shown in this graph). Just plug in the values of a, b and c, and do the calculations. What does it mean to find all […]

What is the formula for a polynomial function? A polynomial is a function of the form f(x) = anxn + an−1xn−1 + + a2x2 + a1x + a0 . The degree of a polynomial is the highest power of x in its expression. What are examples of polynomial functions? Basic knowledge of polynomial functions Polynomial […]

What are the formulas for work and power? That equation is:Work = Force • Displacement • Cosine(theta)W = F • d • cos(theta)Power = Work / time.P = W / t.P = F • cos(theta) • (d/t)P = F • v • cos(theta)PEgrav = m•g•h.KE = 0.5 • m • v2 What is a unit […]

How is Darcy’s Law calculated? The hydraulic head is measured by determination of the vertical position of the water table in a well relative to a reference surface. Darcy’s law says that the discharge rate q is proportional to the gradient in hydrauolic head and the hydraulic conductivity (q = Q/A = -K*dh/dl). WHAT IS […]
