(q7) determine the graph of the polar equation r = 12/6+4 cos theta.

ANSWER

b.

EXPLANATION

The given polar equation is,



Cross multiply to get,





Substitute,



and















This is an ellipse whose center is shifted to the left with orientation on the x-axis

The correct choice is B.

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
