What is partial derivative of z=(2x+3y)^10 with respect to x,y?
maw [93]
Not sure if you mean to ask for the first order partial derivatives, one wrt x and the other wrt y, or the second order partial derivative, first wrt x then wrt y. I'll assume the former.

\dfrac\partial{\partial x}(2x+3y)^{10}=10(2x+3y)^9\times2=20(2x+3y)^9

\dfrac\partial{\partial y}(2x+3y)^{10}=10(2x+3y)^9\times3=30(2x+3y)^9

Or, if you actually did want the second order derivative,

\dfrac{\partial^2}{\partial y\partial x}(2x+3y)^{10}=\dfrac\partial{\partial y}\left[20(2x+3y)^9\right]=180(2x+3y)^8\times3=540(2x+3y)^8

and in case you meant the other way around, no need to compute that, as z_{xy}=z_{yx} by Schwarz' theorem (the partial derivatives are guaranteed to be continuous because z is a polynomial).

Which of the following descriptions represents the transformation shown in the image​
Viktor [21]

Answer:  A. 270° rotation, 3 units left, and 2 units up

<u>Step-by-step explanation:</u>

C = (1, 1)        D = (3, 3)          E = (2, -2)

270° rotation counterclockwise means (x, y) = (y, -x)

new C = (1, -1)        new D = (3, -3)         new E = (-2, -2)

3 units left means subtract 3 from the x-coordinate

newer C =( -2, -1)        newer D = (0, -3)      newer E = (-5, -2)

2 units up means add 2 to the y-coordinate

C' = (-2, 1)       D' = (0, -1)       E' = (-5, 0)

Since the first option worked, there is no need to check the other options.
