Determine if the graph is symmetric about the x-axis, the y-axis, or the origin.

gulaghasi [49]

This equation is an example of a Limacon with inner loop. By using the symmetry tests where:

POLAR AXIS/HORIZONTAL:
replace a) θ by -θ, b) r by -r and θ by π-θ

VERTICAL AXIS:
replace a) θ by π-θ, b) r by -r and θ by -θ

POLE:
replace a) θ by π+θ, b) r by -r

If any of these rules, after replacing it in the equation, results to the original equation (making it the equivalent) then it is symmetrical to that axis.

In this case, it is only symmetrical about the polar/horizontal axis.

Given the line segment , state the ratio of the segment partitions as. Be sure to reduce fractions

Effectus [21]

Answer/Step-by-step explanation:

Line segment AB consists of segment AC and segment CB.

AC = 7 cm

CB = 21 cm

The entire segment, AB = 21 + 7 = 28cm

The ratio of the segments partitions can be stated as follows:

Ratio of AC to CB = AC:CB = 7:21 = 1:3 = $\frac{1}{3}$
