determine the equation of the parabola (simplified) with roots -3+sqrt6 and -3-sqrt6, and passing through the point (-1,4)
klio [65]

Given:

Roots:

\begin{gathered} -3+\sqrt[]{6} \\ -3-\sqrt[]{6} \end{gathered}

Point: (-1,4)

To determine the equation of the parabola with the given roots and point, we find the missing values first.

Since the roots are given, we can say that the equation is:

y=a(x+3-\sqrt[]{6})(x+3+\sqrt[]{6})

Next, we expand the terms.

y=a(x^2+6x+3)

Then, we plug in x= -1, and y=4 into the equation to get the value of a.

\begin{gathered} y=a(x^2+6x+3) \\ 4=a((-1)^2+6(-1)+3) \\ \text{Simplify and rearrange} \\ 4=a(-2) \\ a=\frac{4}{-2} \\ a=-2 \end{gathered}

So,

undefined

Answer:

Well 5 cups.

Step-by-step explanation:

Well you see, you have this right:

2*10=20

in which 2 equals Blue, 10 equals Yellow, and result equals green, so now we have 1 instead of 2, right? So that means 2:2=1, so you got to do this:

2*10=20

(2:2)*(10:2)=1*5=5, So the final answer is 5 cups of yellow cups Now please give me 20 pts
