yulyashka [42]
17113 divided by 100=171.13

171.13*10=1711.3

17113+1711.3=18824.3

You can then round this to get a whole number if you need to.

The vertex of a parabola is (0,0)and the focus is (1/8, 0) . What is the equation of the parabola?
Aleonysh [2.5K]

The equation of a parabola whose vertex is (0, 0) and focus is (1 / 8, 0) is equal to x = 2 · y².

<h3>How to derive the equation of the parabola from the locations of the vertex and focus</h3>

Herein we have the case of a parabola whose axis of symmetry is parallel to the x-axis. The <em>standard</em> form of the equation of this parabola is shown below:

(x - h) = [1 / (4 · p)] · (y - k)²     (1)

Where:

  • (h, k) - Coordinates of the vertex.
  • p - Distance from the vertex to the focus.

The distance from the vertex to the focus is 1 / 8. If we know that the location of the vertex is (0, 0), then the <em>standard</em> form of the equation of the parabola is:

x = 2 · y²     (1)

The equation of a parabola whose vertex is (0, 0) and focus is (1 / 8, 0) is equal to x = 2 · y².

Without his pencil or calculator, Joey knows that 2x³+3x²− 1 = 0 has at least one real solution. How does he know?
vova2212 [387]

Answer: Find the discriminant

Check explanation

Step-by-step explanation:

b^2-4ac

if it is equal to 0 there is no solution

Greater then 0 there is 2 real solution

Less then 0 there is 1 real

3^2-4(2*-1)

9-4(-2)

9(8)

72 there is at least one real solution
