Which statement is true about the function f(x)= the square root of x? a. the domain of the graph is all real numbers. b. the range of the graph is all real numbers. c. the domain of the graph is all real numbers less than or equal to 0. d. the range of the graph is all real numbers greater than or equal to 0.

well first off do you understand what it means when it says the "square root of x"?

314.16 m

Step-by-step explanation:

The distance across the track is 100 metres. This means that the diameter is 100 m.

The track is circular, so, we need the circumference.

The circumference of a circle is given as:

C = πD

where D = diameter

Therefore, the circumference of the track is:

C = π * 100 = 314.16 m

She walked a distance of 314.16 m
