Answer:
Either B or D is the answer
F(x) = x² - 4x -5, factored is simply f(x) = (x - 5)(x + 1).
if you zero out f(x), namely 0=(x-5)(x+1), that simply gives you the zeros of 5 and -1.
now, from ----- -1------0---------------------------------5, notice from -1 to 5, there are 6 units, and half of 6 is 3, so, the half-way is 3 units away from either zero.
so we can get to the half-way point by -1 + 3, or 2, x = 2, that's where the vertex is at, but you already knew that, and of course the y-coordinate is at f(2) = (2)² - 4(2) - 5, which is -9, so the vertex is indeed at (2, -9).
now to draw it, well, surely you can, simply use the zeros location, -1 and 5, and draw a bowl between them, with the bottom of the bowl at 2, -9.
Im not sure on how you went about wording your questions but the answer for
<span>A circular piece of glass has a radius of 0.8 meters. The glass sells for $4.60 per m². What is the total cost of the circular piece of glass? Use 3.14 for pi. $2.01 $9.24 $23.11
is B.$9.24
This is all i could get from what you wrote.
