Answer:

Step-by-step explanation:

because The curve C crosses the x-axis at the origin and at the points A and B => the x coordinates of A and B are the solution of the equation:

x(x + 4)(x - 2) = 0

<=> x = 0

x = -4

x = 2

because the x-coordinates of the points A and B aren't 0 and the x-coordinate

of A is a negative value

=> the x-coordinate of A is -4

the x-coordinate of B is 2

An ellipse has a center at the origin, a vertex along the major axis at (20, 0), and a focus at (16, 0). the equation of the ell

olga_2 [115]

If the center is at (0, 0) and the vertex is at (20, 0), then the distance, a, is the length from the center to the vertex, 20. The distance from the center to the focus is c. The distance from the center to the focus is 16, so c = 16. The formula we use to find the focus is $c^2=a^2-b^2$ . We have our c value and our a value, so we will sub in those to find b. $16^2=20^2-b^2$ and 256 = 400 - b^2. -b^2 = -144, so b = 12. There you go!
