Answer:
Step-by-step explanation:
The shape of this graph is that of a parabola. In this case the parabola opens down. The general form of the equation of such a parabola is
y = a(x - h)^2 + k, where (h, k) is the vertex and a is a coefficient to be determined.
In this particular case we can obtain the coordinates of the vertex (h, k) from the graph. They are (3, 4). Thus, h = 3 and k = 4. The graph goes through (1.5, 0). Use this information to determine the value of the coefficient a:
Then the equation of this parabola must be y = a(x - 3)^2 + 4.
0 = a(1.5 - 3)^2 + 4
Then:
0 = a(-1.5)^2 + 4, or
0 = 2.25a + 4, or
2.25a = -4, or
a = 16/9
Thus, the final result: The equation of this parabola is
y = (16/9)(x - 3)^2 + 4
whose graph is a parabola that opens down and has vertex (3, 4).
Answer:
2x+30=x+80 (corresponding angles)
2x-x=80-30
x=50
Thank me here.... a irregular hexagon lol just need some points for helping
One of the cut pieces of paper has...
3 sides (Unless you include the front and back bc it is paper)
3 angles
I hope this helps :)
Answer:
17.3
Step-by-step explanation:
stem a leaf plot look it up
so (Σ8, 12, 15, 18, 18, 20, 21, 23, 23, 23, 27)/12
(20 + 33 + 38 + 44 + 46 +27)/12
(91 + 117)/12
208/12
about 17.3333333333
