In plain and short, a function has no x-coordinate Repeats, if there's an x-coordinate Repeat, then is not a function.
Answer:
4
Step-by-step explanation:
The distance between the two points is (-1,-4) - (-5,-4)
Surface area of a ball:
S=4πr^2=4*π*5^2=100π
Volume of a circle:
V=4/3*π*r^3=4/3*π*125=(500/3)*π=165π
The approximate surface-area-to-volume ratio would be 1:1,5
