Find all the first and second order partial derivatives of $f(x, y) = 7 \sin(2x + y) - 4 \cos(x - y)$. A. $\frac{\partial f}{\partial x} = f_x = 14\cos(2x+y)+4\sin(x-y)$ B. $\frac{\partial f}{\partial y} = f_y = 7\cos(2x+y)-4\sin(x-y)$ C. $\frac{\partial^2 f}{\partial x^2} = f_{xx} = -28\sin(2x+y)+4\cos(x-y)$ D. $\frac{\partial^2 f}{\partial y^2} = f_{yy} = -7\sin(2x+y)+4\cos(x-y)$ E. $\frac{\partial^2 f}{\partial x\partial y} = f_{yx} = 14\cos(2x-y)-4\sin(x-y)$ F. $\frac{\partial^2 f}{\partial y\partial x} = f_{xy} = 14\sin(2x-y)-4\cos(x-y)$ Note: You can earn partial credit on this problem.

Suppose V is a subspace of R^(n), and S is a set of vectors in V whose span is the subspace W of V. Among the statements below select the correct one: **1.The orthogonal complement of S in V is the same orthogonal completement of W in V. **2. Every vector of S belongs to the orthogonal complement of S in V. **3. If u is a vector in V which belongs to both W and its orthogonal complement in V, then u=0. **4.If u is a vector in V which belongs to both W and its orthogonal complement in V, then u belongd to S. **5. If u is a vector in V which belongs to both W and its orthogonal complement in V, then |u|=1. **6. If V has dimension 10, and S contains 7 vectors, then the dimension of W^((perpendicular))is at most 3. **7. If V has dimension 10, and S contains 7 vectors, then the dimension of W^((perpendicular))is at most 7. **8. If V has dimension 10, and S contains 7 vectors, then the dimension of W^((perpenndicular))is always 3.

Sherman (2022) asserts, "There is a limit to what we can reasonably expect from teaching SEL skills, and in some cases, they carry wide, perhaps outsized expectations, especially when it comes to treating mental illness, which is distinct from mental health." Which of the below statement/s support/s his main conclusion? Group of answer choices SEL is not designed to address (diagnose or treat) mental illness, though it may create conditions for noticing and concern. Making the distinctions between mental wellness and mental illness, and understanding the needs for professional intervention with the latter and the role that can be played universally with SEL, is more important than ever, given the explosion of mental illness needs. SEL and mental illness are each other's obverse. Both A and B are correct.
