What is the value of the natural logarithm when x=0.4 is rounded to the nearest hundredth?

Answer:
Step-by-step explanation:
Since x is lesser than 1, then value of its natural logarithm must be negative. Likewise, the natural logarithm is a transcendental function and an irrational number, then it can only be estimated by approximations. One approach is using Taylor Polynomials, whose approximation is:

Answer:
- circle
- y-axis
- 5 units
Step-by-step explanation:
It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.
The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.
