The vertex is when x=-b/2a, which is also the line of symmetry.
in this case, b=6, a=3, so x=-6/6=-1
when x=-1. y=3-6-1=-4
another way to do it is to write the equation into vertex form by making a square:
3x²+6x-1
3(x²+2x-1/3)
3(x²+2x+1-1-1/3))
3(x²+2x+1-4/3))
notice the bold part makes a square:
3(x+1)²-4
Either way,
the vertex is (-1, -4)
the axis of symmetry is x=-1
the coefficient of x² is 3, a positive number, so this parabola opens upward. the function has a minimum value of y=-4
the range is all real number larger than -4
The cross section is a rectangle, which is a type of square.
Answer:
60.96 cm
Step-by-step explanation:
you do proportions
1 in = 2.54
24in= ?
you multiply 2.54 by 24
Well K is the sum of two integers so the product equals 2*11, as a Hero pointed out:
ac=2*11=22
k=sum of two integers so now it = to 22
