2.) A 75 kg kite surfer is pulled 100 m by a 30 N force at an angle of 50 degrees. The water exerts a frictional force of 10 N. What is the net force

on the kite surfer?

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."
