The graph that has an axis of symmetry at x = 3 is f(x) = x2 – 6x – 1.
You can find the axis of symmetry by using the equation to find the x value of the vertex. The x value of the vertex is always the axis of symmetry in a quadratic graph. The equation is below.
x = -b/2a
In this equation, a is the coefficient of x^2 and b is the coefficient of x. If we use the numbers from the last equation in your list, a = 1, b = -6.
x = -b/2a
x = -(-6)/2(1)
x = 6/2
x = 3
-$<span>25 balance does not mean you have </span>$<span>25 credit but that you owe </span>$25, the absolute value of -$<span>25. Just like the absolute value of 5 would be -5. its just the opposite.</span>
If you want to evaluate what percent of 550 is 4, you can do this in two following steps.<span>
<span>First, you have to write it as a fraction: 4</span>/550.
Second, you have to transform this fraction to
percent: (4/550)*100%.
(4/550)*100% = 0.0072727272727273*100% =
0.727%
<span>The correct result is </span>0.727%.</span>
Answer: 72
Step-by-step explanation:
A = bh
A= (12)(6)
base = 5
height = 4
hypotenuse = sqrt ( 5^2 +4^2) = sqrt(25+16) = sqrt(41)
5+4 = 9
so perimeter = 9+ sqrt(41)
answer is the 3rd one.
