Which is the focus of a parabola with equation y^2=-12x?
a. (-3,0)
b. (0, -3)
c. (0,3)
d. (3,0)

Focus of the given parabola is (-3,0)

Step-by-step explanation:

Given equation of parabola is:

y² = -12x

Standard equation of parabola is :

y² = 4px  

Parabola opens right or left.

Focus of this parabola is (p,0)

y² = -12x is opens left.

y² = 4(-3)x

Here value of p = -3

So, the focus of given parabola is : (-3,0)

That's the final answer.

I hope its help you.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
