Explorer 35's orbit measured 11,400 kilometers across its long dimension. what was the orbit's semimajor axis in kilometers? a. 5,700 kmb. 9,600 kmc. 11,400 kmd. 22,800 km

option (a)

Step-by-step explanation:

Length of long dimension = 11400 km

It means it is the length of major axis.

So, the length of semi major axis = 11400 / 2 = 5700 km

Thus, the length of semi major axis is 5700 km.

i think it is 18

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
