Answer:
A 3.14159.......
Step-by-step explanation:
We need a non rational number
3.14159 is pi which is an irrational number
1/7, .27(repeating) and .83333(repeating) can be written in the form
a/b where a and b are integers, which makes them rational
Answer:
A ≈ 9.6 units²
Step-by-step explanation:
the area (A) of the triangle is calculated as
A = product of 2 sides × sin (angle between them ) , that is
A = 3 × 5 × sin40° = 15 × sin40° ≈ 9.6 units² ( to the nearest tenth )
Should be line of symmetry, for in other words line
t

Answer:
Explanation:
Compute the magnitude:
∣∣→a∣∣=√(−10)2+62+(−7)2
∣∣→a∣∣=√100+36+49
∣∣→a∣∣=√185
To obtain the unit vector of →a=(−10,6,−7), we divide each component by √185 but we should rationalize 1√185 to √185185:
ˆa=(−10√185185,6√185185,−7√185185)
