Answer:
Oh this one is quite simple
nth Term = 2n + 4
Sin x = sin 2x
x=2kπ+2x
x=-2kπ
also
x=2kπ+π-2x
3x=2kπ+π
x=2kπ/3+π/3
Answer:
30
Step-by-step explanation:
Permutation equation: ![\frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
n = Total number of objects, r = Number of objects selected
![_6P_2=\frac{6!}{(6-2)!}=30](https://tex.z-dn.net/?f=_6P_2%3D%5Cfrac%7B6%21%7D%7B%286-2%29%21%7D%3D30)
Answer:
isn't this already fully simplified?
Step-by-step explanation:
Answer:
|96.55−0.02|= x
|96.55+0.02|=x
Step-by-step explanation:
Given that:
Measured length of beam = 96.55 cm
Measurement accuracy = plus or minus (± 0.02cm)
Limits of actual length of the beam:
Let limit of actual length = x
Lower limit :
|measured length - accuracy| = x
|96.55 - 0.02| = x
96.53) x
Upper limit :
|measured length + accuracy| = x
|96.55 + 0.02| = x
96.57 = x
