Tiffany sells two kinds of homemade tomato sauce. A quart of her Tuscan sauce requires 6 tomatoes and 1 cup of oil. A quart of h

nevsk [136]

From the problem,
x is the number of quarts of Tuscan sauce and
y is the number of quarts of marinara sauce

We add the following variables
t as the number of tomatoes
c as the number of cups of oil
z is the total profit

The constraints are the following
x = 6t + c
y =5t + 3c
6t + 5t ≤ 45
c + 3c ≤ 10
z = 4x + 5y
where z is to be maximized

Which is the standard form of the equation of the parabola that has a vertex of (–4, –3) and a directrix of x = 2?

Zielflug [23.3K]

Answer:

Equation of the parabola is $\left(y+3\right)^{2}=-24(x+4)$

Step-by-step explanation:

We have to find the equation of a parabola with vertex is (-4,-3) and a directrix x=2.

As vertex is (-4,-3) that means parabola is in third quadrant.

So the standard formula of the parabola will be y²= -4px through origin (0,0).

But when a parabola is shifted from origin to the left of y axis so the equation will be (y-shifting form y axis)² = -4(distance between vertex and directrix)(x-shifting from x axis)

$\left\{y-(-3)\right\}^{2}=(-4\times 6)\left\{x-(-4)\right\}$
