Vectors and angles a ship is sailing through the water in the english channel with a velocity of 22 knots along a bearing of 157° (knots being a unit used to measure the speed of aircrafts and boats). the current has a velocity of 5 knots along a bearing of 213°. find the resultant velocity and direction of the ship. (remember that bearing is measured clockwise from the north axis). 1) 25 knots at 166.5 degree 2) 27 knots at 350 degree 3) 166.5 knots at 25 degree 4) 350 knots at 27 degree

We have been given that a ship is sailing through the water in the English Channel with a velocity of 22 knots along a bearing of 157°.

Further we have been given that current has a velocity of 5 knots along a bearing of 213°.

Therefore, angle between the direction of ship and direction of current will be

We can find the magnitude of resultant by using parallelogram law of vectors.

Upon substituting in this formula, we get

Therefore, resultant velocity of the ship is 25.14 knots.

We find the angle of resultant from P, that direction of ship using the formula

Upon substituting the values, we get

Therefore, bearing of the resultant is

Hence, option (A) is the correct choice!

step-by-step explanation:

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
