Step-by-step explanation:
Given a quadratic in standard form, ax² + bx + c : a ≠ 0
Then the axis of symmetry is a vertical line with equation x = h
where h is the x- coordinate of the vertex.
The x- coordinate of the vertex is
= -
f(x) = 5x² - 3x + 5 ← is in standard form
with a = 5 and b = - 3, thus
= -
=
Thus the equation of the axis of symmetry is x =
Answer:
<u>22.73%</u> of ounces Isabella has left of her cola.
Step-by-step explanation:
Given:
Isabella has a 22 ounce cola. She drinks 17 ounces.
Now, to find the percentage of ounces Isabella has left of her cola.
Total ounces of cola = 22.
Ounces of cola Isabella drink = 17.
So, the ounces of cola she left:
<em>Total ounces of cola - ounces of cola Isabella drink.</em>
<u><em>Thus, 5 ounces of cola she left.</em></u>
Now, to get the percentage of cola she left:
<u>Rounding the percentage to the nearest hundredths is 22.73%.</u>
Therefore, 22.73% of ounces Isabella has left of her cola.
