Compute the indicated derivative using the chain rule. y = U , U = x - 8; ]x dy dx X Compute the indicated derivative using the chain rule. y = 3x2 - 4X; - dx dy x = 2 dx dy Find the indicated derivative. In this case, the independent variable is a (unspecified) differentiable function of t. y = x100 + 90x-1 Find Dy dt dy dx dt dt Find the indicated derivative. In this case, the independent variable is a (unspecified) differentiable function of t. y = V x+ x = 9 when t = 1, - dx dt It = 1 = -3 Find - dy dt = 1 dy dt Find the indicated derivative. In this case, the independent variable is a (unspecified) differentiable function of t. 5 = 4r+r-1 Find it dr dt X dt Find the indicated derivative. In this case, the independent variable is a (unspecified) differentiable function of t. 5 = - 1 -+ 10.4 Find Us dt as dt dt
