The equation for an ellipse with a horizontal major axis is x²/a² +y²/b² =1 . the orbit for mercury can be plotted on the coordinate plane with the center at the origin and the sun located at one focus. use this information and the mercury’s calculated mean distance from the sun to find the value of a. express your answer in millions of miles

  n=   0.0000 - 0.3750 i  

  n=   0.0000 + 0.3750 i

step-by-step explanation:

one of these should be correct

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
