Which of the following u-substitutions for ∫ (x(x+2)^2)/(sqrt(x))dx results in 2∫u^(2)(u^(2)+2)^(2)du?

A

Step-by-step explanation:

u = sqrt(x)

x = u²

dx/du = 2u

dx = 2u × du

x(x+2)²/sqrt(x) . dx

u² × (u²+2)]/u × 2udu

2 × u²(u²+2).du

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
