Determine magnitude and direction using standard Cartesian coordinate system

Please answer question and just send me the paper solutions asap dont type the answer please faster and show the angle using tan and cos please and answer like m/s with directions asap please Question 1ab please faster asap

i need to know if i got this right my answer was 2200 and magnitude was 400 please explain if i got this wrong

Every year the Earth travels about 10^9km as it orbits the sun. What is Earth's average speed in km/h.  Did I do this correct?  savg=distance/time (365days*24 hours) =8,760 hours 10^9/8,760 =1.14*10^5km/h

The graph below illustrates a driving trip from the town of Goodfield to the town of Peoria. distance (in miles) 35 30 25 20 15 10 5 0 0 0.25 0.5 0.75 1 time (in hours) (a) How far apart are the two towns? miles (b) Find the slope of the linear graph. select units (c) What does the shape of the graph tell us about the trip? ---Select---

Consider another formula to estimate someone's height based on foot length: foot length (in inches) X 6.54 = height (in inches) Use this formula to calculate your own height: Your height based on this formula: inches. Your actual height = inches. Is this a more accurate mathematical relationship between foot size and height? Explain why or why not.

What is the number of latitude degrees between place A (60 N, 75 W) and place B (65 S, 75 W)

19. A plane travels 125 miles on a bearing of N 18 degrees E and then changes its course to N 56 degrees E and travels another 120 miles. Find the total distance traveled north and the total distance traveled east. Apply the rules regarding the use of significant digits when determining your answers. ​ Find the total distance traveled north. ​ __________ mi ​ Find the total distance traveled east. ​ __________ mi

Please give details as much as possible with diagram.

North Pole equator South Pole The sketch is a cross section through the earth, showing two points that have a difference in latitude of angle 0. The mean radius R of the earth is 6.371 x 10°meters. A nautical mile is defined as 1852 meters exactly. Using these data, calculate how many nautical miles there are between two points on the earth's surface that have the same longitude but have latitudes that differ by 1.000 degree. (Just in case: the definition of angle, in radians, is the arc of a circle it subtends divided by the radius of the circle. A circle is 2n radians or 360°.) There are = nautical miles between two points with latitudes differing by 1.000°. (Enter your answer as a number, without exponents and without units, but with appropriate significant figures.)
