Afox can run at a speed of 42 miles per hour. how many feet per second is this?

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
