x=11
Answer:
A. 2x
Step-by-step explanation:
The slope is y values over x values
(0,0)
(1,2)
2-0 over 1-0
2/1 = 2
Answer:
b. 0.850887688656
Step-by-step explanation:
Unless the argument of the sine function is specified in degrees or some other angle unit (revolutions, grads, minutes, seconds), it must be assumed to be radians. Here, the argument 310 is not shown as 310°, so we must assume it is 310 radians.
sin(310) ≈ 0.850887688656

<em>Additional comment</em>
sin(310°) ≈ –0.766044443119
A radian is dimensionless, indistinguishable from a pure number.
Given the vertex of the parabola at point (2, -3):
The quadratic function in vertex form is:
f(x) = (x - 2)^2 - 3
where the vertex (h, k) is the minimum point = (2, -3).
I’m not really sure but I would say c
