Answer:
least common multiple (LCM) of 9 and12 is 36
How do you want this solved?
8p-7 is the eqation your using, -7 is spaces back (this is your numer for each of 8 turns) 8 times 7 eqalls 56 make this a negative, -56 spaces
Answer:
±2.18 cm
Step-by-step explanation:
The definition of the sine of an angle (θ) is ...
Sin = Opposite/Hypotenuse
Then the hypotenuse (h) is found from ...
h = Opposite/sin(θ)
Differentiating with respect to θ gives ...
dh/dθ = Opposite×(-cos(θ)/sin²(θ))
For the given numbers, this is ...
dh/dθ = (36 cm)×(-√3/2)/(1/2)² = -72√3 cm/radian
The error of ±1° corresponds to ±π/180 radians, so the error is estimated to be ...
error = (dh/dθ)Δθ = (-72√3 cm/radian)(±π/180 radians) = ±0.4π√3 cm
error = ±2.18 cm
