The function f (x) x ^ 3 + ax ^ 2 + BX + 16 has extremum 10 when x = 1

Function f (x) = x ^ 3 + ax ^ 2 + BX + 16
Derivative function f '(x) = 3x ^ 2 + 2aX + B
When x = 1, there is an extreme value, the derivative is equal to 0, f '(1) = 3 + 2A + B = 0, that is, 2A + B = - 3
This is the function value (extreme value) is equal to 10, f (1) = 1 + A + B + 16 = 10, a + B = - 7, that is, ②
Solving the equations, we get a = 4, B = - 11

We know that y = f (x + 2) is an even function defined in R, and when x ≥ 2, f (x) = 3 ^ X-1, then the value of F (1)

If x + 3y-2 = 0, then the minimum value of 3x + 27y + 1 is ()
A. 339B. 1+22C. 6D. 7

According to the properties of the basic inequality, there are 3x + 27y ≥ 23x · 27y = 23x + 3Y, if and only if 3x = 27y, take the equal sign. If x + 3Y = 2, then 3x + 27y ≥ 232 = 6, then the minimum value of 3x + 27y + 1 is 7. So D is chosen

In math class, the teacher asked a question: "what is the result of subtracting 1 from the square of an odd number?" Please answer this question

[method 1]: when the odd number is 1, 3, 5, the number is 0, 8, 24, and (2 points), so the number should be a multiple of 8. (4 points) then turn to algebra, and give points according to method 2. (Note: check with - to two numbers, do not give points if there is no answer, give 1 point if the answer is an integer, give 1 point if the answer is an even number, give 2 points if the answer is a multiple of 4, and give 2 points if there are more than three numbers [method 2]: let the odd number be 2n + 1 (n is an integer), (1) then the number is (2n + 1) 2-1 = 4n2 + 4N = 4 (N2 + n) = 4N (n + 1). (3 points) (here: the answer is 4 points for the multiple of integer, even number and 4). Because n is an integer, there must be an even number between N and N + 1. (4 points), so n (n + 1) is an even number (or a multiple of 2) So the result is a multiple of eight

Let Z (x, y) be a function determined by the equation sin (XYZ) - 1 / (z-xy) = 1, and find ZX (0,1) (where x is a corner code)
This is the title of the self-taught examination book. I hope you can try your best to answer it,

For the sake of simplicity, the following is Z 'for ZX. Just rewrite it yourself
Substituting x = 0, y = 1 into the equation, we get z = - 1
The partial derivatives of X are obtained on both sides of the equation
cos(xyz)(yz＋xyz')＋1/(z-xy)²×(z'－y)＝0
Substituting x = 0, y = 1, z = - 1, we get Z '= 2
