Answer:

The equation of the axis of symmetry for this parabola is x = 0.

Step-by-step explanation:

For parabola's, it's axis of symmetry always goes through the vertex of the parabola. In other words, the axis of symmetry is vertical line that goes through the x-coordinate of the vertex.

Now, the vertex is given as (0,3) which is at x = 0, y = 3.

Thus, the vertical line that goes through the x-coordinate of the vertex will be x = 0

Thus, the equation of the axis of symmetry for this parabola is x = 0.

If a right circular cone is intersected by a plane that goes through both napped of the cone but not through the vertex, as in t

kramer

Answer:

F. Hyperbola

Step-by-step explanation:

In each napped, you'll have a parabola, combined they form an hyperbola.

It's one of the various shapes that can be produced by a plane intercepting a right circular cone, as you can see in the attached picture.

Each plane intersection is different, based on the angle and the position it passes through.

I hope that helps.

If a=2^3 x 3^7 x 5^3 x 11^4 and b= 2^2 x 3^5 x 7^2 x 11 x 13 , find the following:

Natalka [10]

Answer:

10,692

Step-by-step explanation:

GCF stands for Greatest Common Factor.

The way to find it is easy once you have the prime decomposition.

Search for common factors in the decomposition and take the least power, then multiply them all.

So, in our case, as the numbers are already broken down into prime factors , we have

$GFC(a,b)=2^2.3^5.11=10,692$

Whats is a 3 step problem that can represent the expression 3x + (-5) = 19

GrogVix [38]

Answer:

$x=8$

Step-by-step explanation:

$3x-5=19\\$

The first step is to add -5 to both sides:

$(3x-5)+5=19+5\\3x=24$

The next step is to divide 3 on both sides:

$\frac{3x}{3} =\frac{24}{3}$

$x=8$

The table shows different possibilities for the number of students to the number of fans present at a football game. Which ratio

Deffense [45]

Answer: 7:49

Step-by-step explanation: As you can see in the table, if you divide the number of fans present at a football game by the number of students, you would always get 7. So, 7:49 is a choice because if you divide 49 by 7, you get 7. Hope this helps!!
