Answer:

Step-by-step explanation:

  • We must prove that : sin²∝ + sin²∝ × tan²∝ = tan²∝
  • sin²∝+ sin²∝× tan²∝ = sin²∝(1+tan²∝)
  • 1+ tan²∝= 1/cos²∝
  • So: sin²∝(1+tan²∝)= sin²∝/cos²∝ =tan²∝

Excerpt from a school newspaper:
Anika [276]
A) There was no change in the number of students on honor roll from one year to the next. This is noticeable because 200/1000 = .2 just as 20%/100% = .2 or 20/100 = .2. So there never was a change!

the density of pure gold 1,204 pounds per cubic foot? how many cubic feet is 481.6lbs of pure gold?
Nadusha1986 [10]

Answer:

Volume of Gold = 0.4 cubic feet.

Step-by-step explanation:

First we have to make sure the units are same as the units the answer is required in.

Answer should be given in cubic feet.

Density is given in pounds per cubic foot. And Mass is given in pounds. So units are in order. Therefore, we can go ahead with the calculation.

The Density of Gold = [Mass of Gold/Volume of Gold]

By substituting values,

1204 ponds per cubic foot = [481.6 pounds / Volume of gold]

Making Volume of God the subject of the equation,

Volume of Gold = [481.6 pounds / tex]1204[/tex] ponds per cubic foot ]

Volume of Gold = 0.4 cubic feet.
