The answer would be 6- 52/(x+16)
X=9.5 all you do is divide the total by the other factor you have
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
So you are given the amount he sold which is $7300, and you are given his commission rate so all you have to do is this
7300 x 0.12 = 876
Therefore, his amount of commission is 876 dollars
