select the table of values where the quadratic function changes direction at a different value of x than the others.
imagine that this is a graph.
a.
x -3 -2 -1 0 1 2 3
y 2 3 2 -1 -6 -13 -22
b.
x -3 -2 -1 0 1 2 3
y 2 3 2 -1 -6 -13 -22
c.
x -3 -2 -1 0 1 2 3
y 4 3 4 7 12 19 28
d.
x -3 -2 -1 0 1 2 3
y 1 -1 1 7 17 31 49

x-3-2-10123

y2819127434

Step-by-step explanation:

The point where the quadratic function changes direction (which is the maximum or the minimum of the function) is called the turning point. In options A, B and C the turning point is at (-2, 3), and in option D the turning point is at (-2, -1).

Given that all of them correspond to the same x-value and options A and B are the same, I assume one of them was mistyped. Given the following option:

x-3-2-10123

y2819127434

we see that the turning point is at (2, 3) which represents a different x-value.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
