The best estimate would be one kilogram since one gram is about the mass of a paperclip.

1 kilogram is equivalent to around 2 lbs, so that'd be your answer.

Prove cos^4 X +sin^4 x= 2cos^2 x for any acute angle​
Nikolay [14]

Answer:

Proof provided in the explanation.

Step-by-step explanation:

\cos^4(\theta)-\sin^4(\theta)+1

I'm going to rewrite that middle term so I can apply Pythagorean Identity, \sin^2(\theta)=1-\cos^2(\theta):

\cos^4(\theta)-(\sin^2(\theta))^2+1

\cos^4(\theta)-(1-\cos^2(\theta))^2+1

Use (a+b)^2=a^2+2ab+b^2:

\cos^4(\theta)-[1-2\cos^2(\theta)+\cos^4(\theta)]+1

Distribute:

\cos^4(\theta)-1+2\cos^2(\theta)-\cos^4(\theta)+1

Combine like terms:

\cos^4(\theta)-\cos^4(\theta)-1+1+2\cos^2(\theta)

Applying inverse property of addition:

0+0+2\cos^2(\theta)

Applying identity property of addition:

2\cos^2(\theta)
