Answer:
Step-by-step explanation:
Please use " ^ " to indicate exponentation: y= x^2 + 11x + 24. Thanks.
Because x^2 is positive, the graph of this parabola opens up.
We can find the vertex and roots (zeros) as follows, using the quadratic formula:
With a = 1, b = 11 and c = 24,
-11 ± √ [ (11^2-4(1)(24) ] -11 ± √25
x = ------------------------------------ = --------------- = -3 and x = -8
2(1) 2
This tells us that the x-intercepts are at (-3, 0) and (-8, 0). The minimum value is at x = -b / (2a), which here is x = -11 / [2] = -5 1/2 (which is halfway between the zeros).
The vertex (and thus, the minimum) is at (-5 1/2, f(-5 1/2) ).
Answer: d=2r
Step-by-step explanation:
The diameter is twice the size of the radius which is 2r
Answer:
A, AA similarity
Step-by-step explanation:
the first similar angle is from the vertical angles and there are 2 more because the end sides are parallel and when they intersect with the same line it will make it have the same degree. It may look SAS but the figure may not be drawn to scale and there is no proof for it.
