Answer:
A cardioid
Step-by-step explanation:
A cardioid is a curve in the shape of a heart traced by a point on the circumference of a circle as it rolls around a fixed circle of the same radius.
The equation of vertical cardioid is ±
Given the polar curve is 4
This is an equation of vertical cardioid.
So, it represents a cardioid.
Answer:
Step-by-step explanation:
Angles a and b are opposite, so they are equal. The same is true for angles O and 3b.
So, the four angles are actually (starting from the left and going clockwise) 3b,b,3b,b
These four angles sum up to 360, so we have
And since a and b were the same, a is also 45 degrees.
1.25=x+(x+4)
1.25=0.10x+0.05(x+4)
The answer is B.
Hope this helps :)
