Splet23. dec. 2024 · Best answer Answer is (A) 75 Let us consider y = f (x) = (x2 + 250/x) and dy/dx = f' (x) = 2x - 250/x2 Substituting f (x) = 0, we get 2x3 - 250 = 0 ⇒ x3 = 125 ⇒ x = 5 … Splet22. apr. 2024 · Now, for given sum of two numbers, their product is maximized when they are equal, hence from x 2 + y 2 = 100 we'll have that x 2 y 2 (or which is the same xy) is maximized when x 2 = y 2. In this case x 2 + x 2 = 100 --> x = 50.

The maximum value of f(x) = (x - 2)^2(x - 3) is - Toppr
SpletLet f ( x) = 7 x − x 2 − 10 we have f ( x) = − ( x − 5) ( x − 2) thus 2, 5 are the roots of this function.Between these roots the curve is above x-axis.Thus a = 2, b = 5 thus maximum possible are is 9 2.

SpletTwo numbers r and s sum up to -250 exactly when the average of the two numbers is \frac{1}{2}*-250 = -125. You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2+Bx+C. The values of r and s are equidistant from the center by an unknown quantity u. Splet07. jun. 2024 · In that case, there is no need for bounds (minimum or maximum), as you can simply calculate the variance of the data values in the array with: var ( x) = 1 N ∑ i = 1 N ( x i − x ¯) 2. 2. Now, say, you do not know any of the values; only that there are N. In other words: you have not seen the sample, but only know the sample size. brevard county fsa scores
