There are many reasons why there are differences in price in Lemonade.
The first is the volume or amount of the Lemonade. Obviously, the greater the amount of the Lemonade, the higher is its price.
The price of the lemonade is given, the unit price then is
$4.99/95 ounces = $0.053/ounce
Another reason is the difference in the ingredients. Some Lemonade might have additional ingredients that could make the price higher.
The difference in materials costs in different areas may also be the reason.

What is the equation of the axis of symmetry for this function? H(x) = -X2 + 10x - 11 x = -5 0 x= -10 x = 5 x = 10
siniylev [52]

Given:

The equation of a quadratic function is:

H(x)=-x^2+10x-11

To find:

The equation of the axis of symmetry for the given function.

Solution:

If a quadratic function is f(x)=ax^2+bx+c, then the equation of the axis of symmetry is:

x=-\dfrac{b}{2a}        ...(i)

We have,

H(x)=-x^2+10x-11

Here, a=-1,b=10,c=-11. So, the equation of axis of symmetry by using (i), is

x=-\dfrac{10}{2(-1)}

x=-\dfrac{10}{-2}

x=5

Therefore, the correct option is C.
