an ellipse has a vertex at (5,0), a co-vertex at (0, -3), and a center at the origin. which is the equation of the ellipse in standard form?

Step-by-step explanation:

her center , and is the horizontal radius, and is the vertical radius.

So the center is .

because (5,0) has a distance of 5 from (0,0).

because (0,-3) has a distance of 3 from (0,0).

So the equation is:

Simplifying a bit:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
