a rescue helicopter has flown from its home base to an emergency scene 48 miles away on a heading of 351 degrees. It then takes off for the nearest hospital 39 miles away on a heading of 78 degrees. Since this is an emergency vehicle, the pilot must keep the helicopter at a specific fuel level at all times. If he flies too far he will need to fill up first. Since this is a different hospital from where he needs to know the distance back to home base

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

the correct answer is d

susie has 7 apples

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
