determine the region of the xy-plane where the solution of the de would have a unique solution passing through the point (x0,y0).
(9-y^2)dy/dx=x^4

given equation,

so,

the given point from where the region is passing through is (x₀, y₀)

hence, the unique equation comes out to be

hence unique equation,

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

the answer is b
