Answer:
Step-by-step explanation:
No, because the lines are in the same plane.
In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:
is a constant which helps to determine whether the parabola opens up or down. If 
, then the parabola opens downward and if 
, the parabola opens upwards
is the vertex of the parabola
By looking at the graph, we can first see that the graph opens downwards, meaning that . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.
The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:
The answer is a, 
.
Hello,
We must calculate the volume of water in one hour.
V=15000*PI*0.07²=230,9070600... m^3/h.
Volume of the pond=50*44*.21=462 m^3
Time=462 m^3/ 230.907... m^3/h=2,0008... h≈2 h
Double-time for overtime...so overtime pay is 2(8.50) = 17
40(8.50) + 9(17) = 340 + 153 = 493 <== pay for the week
Answer:
Vertex (1,-25), Intercepts at (6,0) and (-4,0)
Step-by-step explanation:
Axis of symmetry = -b/2a = -(-2)/2(1) = 2/2 = 1 so x=1 is the equation of line
Plug x=1 into equation y=1-2-24=-25
factor for x-intercepts: (x-6)(x+4)
set them equal to zero: x-6=0 so x=6 x+4=0 so x= - 4
