(a) what does the equation x=4 represend in r2 ? what does it represend in r3? illustrate with sketches. (b) what does the equation y=3 represent in r3? what does z =5 represent? what does the pair of equations y=3,z=5 represent ? in other words, describe the set of points (x, y,z) such that y=3 and z=3. illustrate with sketch

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

what "following statement"?

step-by-step explanation:

the football players are volunteering for the test.

happy to

pls mark as brainliest

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20
