Answer:
1) To see whether it is a maximum or a minimum, in this case we can simply look at the graph. f(x) is a parabola, and we can see that the turning point is a minimum. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).

a triangle needs to have 180 degrees in all.
65 + 65 = 130

x = 50 degrees
Answer:
C is correct, D might be correct if you forgot 000 at the end of the question.
Step-by-step explanation:
005 = 5x1 so A is incorrect
945 = 9x100 + 4x10 + 5x1 so B is incorrect
15.859 = 1x10 + 5x1 + 8/10 + 5/100 + 9/1000 + so C is correct
973.001 = 9x100 + 7x10 + 2x1 + 1/1000 so D is incorrect
