I'm stuck on this question. show all work!
an airplane undergoes the following displacements: first, it flies 72 km in a direction 30° east of north. next, it flies 48 km due south. finally, it flies 100 km 30° north of west. using analytical methods, determine how far the airplane ends up from its starting point.

Add all the displacement vectors together, then find the magnitude of this vector sum.

Summing these vectors gives the resultant displacement

and we have

so the plane ends up about 81.9 km away from its starting position.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
