There is no correlation it’s a scattered plot
1 lb = 16 oz
3 1/2 (or 3.5)lbs = 3.5(16) = 56 oz which equals : 2 lbs and 24 oz or 3 lbs and 8 oz or 1 lb and 40 oz
<h3>Answer:</h3>
sec²(x)
<h3>Explanation:</h3>
As required:
... = (sin²(x)/cos²(x))(1 +(cos²(x)/sin²(x))
... = (sin²(x)·(sin²(x)+cos²(x)) / (cos²(x)·sin²(x))
... = 1/cos²(x) = sec²(x)
_____
Alternatively, multiply out the given expression, then use trig identities.
... = tan²(x) + (tan(x)·cot(x))² = tan²(x) +1 = sec²(x)
