Find the critical point of the function. then use the second derivative test to classify the nature of this point, if possible. (if an answer does not exist, enter dne.)f(x, y) = x2 + 2xy + 2y2 − 6x + 10y + 9(x, y) = correct: your answer is correct. finally, determine the relative extrema of the function. (if an answer does not exist, enter dne.)

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

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
