Which graph shape represents the polar curve r = 1 + 4sin(θ)? a cardioid
a rose curve
a limaçon with an inner loop
a limaçon without an inner loop

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.

what is the answer?

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
