Focus (-3,3) vertex (0,3). What is the equation for the parabla

Mathematics

Gwar [14]3 years ago

Answer:

(y - 3)² = 12(x + 3)  

Step-by-step explanation:

The focus is to the right of the vertex, so the parabola is sideways and opens to the right.

The conic form of a sideways parabola is

(y - k)² = 4p(x - h)

The vertex is at h = -3; k = 3

The focus is at (h + p, k) = (-3 + p, 3)

The vertex and focus are three units apart, so p = 3.

The equation of your parabola is

(y - 3)² = 12(x + 3)

The figure below shows the graph of your parabola with its focus and vertex.

Tamiku [17]

Answer:

62 degrees

Step-by-step explanation:

Since lines i and k are parallel, angle b and h are interior angles and are equal to each other. Set up the equation by setting the two equal to each other.

8x-34=5x+2

Subtract 5x from both sides. (it cancels on the right side)

3x-34=2

Add 34 to both sides. (cancels on the left side)

3x=36

Divide both sides by 3.

x=12

Now plug it into either equation since they are equal. I'm gonna use the one for angle h so that it's less confusing.

5(12)+2

60+2

62

The measure of angle h is 62 degrees.
