Answer:
cups
Step-by-step explanation:
Jacob mixes cup of yellow paint for every
cup of blue paint to make green paint.
The ratio of yellow paint to blue paint =
= 5:3
cup of blue paint =
cup of yellow paint
1 cup of blue paint = ÷
cup of yellow paint
⇒ ÷
⇒
Hence, For 1 cup of blue paint needed cups of yellow paint.
Using the given information we found that the equation of the parabola is:
y = (-4/9)*(x - 3)^2 + 5
And its graph is below.
<h3>How to get the equation of the parabola?</h3>
For a parabola with vertex (h, k), the equation is:
y = a*(x - h)^2 + k
Here the vertex is (3, 5), so the equation is:
y = a*(x - 3)^2 + 5
And the y-intercept is y = 1, this means that:
1 = a*(0 - 3)^2 + 5
1 = a*9 + 5
1 - 5 = a*9
-4/9 = a
So the parabola is:
y = (-4/9)*(x - 3)^2 + 5
And its graph is below.
