I need help with my math assignment. I put example question so i could understand without having you give me the answer. Please label everything and thank you so much.

Ex 1:

Find U x V if 0 is the angle between U and V if ||v||=22 and ||u||=30 and 0=pi/6. ______

Ex 2:

Determine if the vectors are orthogonal, parallel, or neither. If neither determine if the angle between them is acute or obtuse if u=(-5,10) and v=(-10,20).

a) orthogonal

b) parallel

c) neither-obtuse

d) neither-acute

Determine if the vectors are orthogonal, parallel, or neither. If neither determine if the angle between them is acute or obtuse if u=(-5,-1) and v=(2,3).

a) orthogonal

b) parallel

c) neither-obtuse

d) neither-acute

Ex 3:

Find the component form of a vector that represents the velocity of an airplane descending at an angle of 225 degrees at 155 miles per hour. Round your answers to the nearest tenth. <_____,_____>

Ex 4:

A soccer player kicks a ball so that it leaves the ground with a velocity of 55 feet per second at an angle of 40 degrees with the ground. Find the magnitude of the horizontal and vertical components of the velocity. Show your work please.
