a,b
Step-by-step explanation:
<span>r=2sin0-3cos0</span>
explain<span>using the formula that links Cartesian to Polar coordinates.<span>∙y=r<span>sinθ</span></span><span>∙x=r<span>cosθ</span></span>then : <span>r<span>sinθ</span>=3r<span>cosθ</span>+2</span>and <span>r<span>sinθ</span>−3r<span>cosθ</span>=2</span>hence <span>r<span>(<span>sinθ</span>−3<span>cosθ</span>)</span>=2</span></span>
<span>⇒r=<span><span>2<span><span>sinθ</span>−3<span>cosθ</span></span></span></span></span>
Circumference of Circle A is is 42pi.
It is the same for all circles. To find the circumference, one must use the constant equation of 2pir. This equation stays the same, no matter what.
F(x) is a way of writing the output of a function, also known as the dependent variable. You are probably used to seeing y in this place, but all you're doing is replacing y with f(x).
