Answer:
B
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 13² + 4² = 169 + 16 = 185 ( take the square root of both sides )
x =
≈ 13.6 ( to 1 dec. place ) → B
Answer:
![=\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=%3D%5Csqrt%7Bx%5E2%2By%5E2%7D)
Step-by-step explanation:
The magnitude of this vector is the square-root of the sum of squares of the horizontal change and vertical change
Let the vector be t
magnitude of t will be
![t=\sqrt{x^2+y^2}](https://tex.z-dn.net/?f=t%3D%5Csqrt%7Bx%5E2%2By%5E2%7D)
The answer to the square root of 64y16 is 8y8.
