Identify the type of polar graph for the equation: r = 3-5cos θ aLimacon with inner loop bCardioid cDimpled limacon dConvex lima

svp [43]

Given the equation:

$r=3-5\cos \theta$

Let's identify the type of polar graph for the equation.

To identify the type of polar graph, use the formula below to get the Cartesian form:

$(x^2_{}+y^2)=r(\cos \theta,\sin \theta)$

Thus, we have:

$(x^2+y^2)=3\sqrt[]{x^2+y^2}-5x$

We have the graph of the equation below:

We can see the graph forms a Limacon with an inner loop.

Therefore, the type of polar graph for the given equation is a limacon with inner loop.

Find the distance between the points (13, 20) and (18, 8).<br><br> 7<br> 11<br> 13

cupoosta [38]

$d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2}}$
$d = \sqrt{(18 - 13)^{2} + (8 - 20)^{2}}$
$d = \sqrt{(5)^{2} + (-12)^{2}}$
$d = \sqrt{25 + 144}$
$d = \sqrt{169}$
$d = 13$
