(goh) = 2(x^1/2)-1
(goh)(9) = 2(9^1/2)-1
= 2(3)-1
= 6-1
= 5
(goh)(9) = 5
u - v = <5, 2> - <2, - 3> = <5 - 2, 2 + 3> = <3, 5>
given a vector <u, v> then the magnitude is √ (u² + v² ) and it's angle of direction is
θ =
(
)
thus the magnitude of <3, 5> = √(3² + 5²) = √34 ≈ 5.83 ( to 2 dec. places )
Θ =
(
) = 59.04° ( to 2 dec. places )
Hey there!:
According to the Pythagorean theorem, the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse (H):
1² + 19² = x²
1 + 361 = x²
x² = 1 + 361
x² = 362
x = √ 362
x = 19.02
Hope this helps!
