we have
Convert to vertex form
we know that
the equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
the vertex is the point 
therefore
<u>the answer is </u>
The y-value of the vertex is 
Answer:
1 : 2
Step-by-step explanation:
Given that,
amount of coloured fabric Gordon use to make his curtain = 24mm
amount of white fabric Gordon use to make his curtain = 1.2cm
To find,
ratio of the amount of white fabric to coloured fabric
1 cm = 10mm
1.2 cm = 1.2 * 10
= 12 mm
<h3>Ratio</h3>
12 / 24
1 / 2
1 : 2
So, ratio of the amount of white fabric to coloured fabric is 1 : 2
Answer:
5) a=79º b=101º
Step-by-step explanation:
I am not entirely sure but I hope it helps! I'm sorry I only know number 5.
It’s 12 because 300 / 25 Equals to 12 so 12x25 equals to 300!
Answer:
