The tangent function is the ratio of "opposite side" to "adjacent side." It so happens that the "adjacent side" is negative in Quadrants II and III, whereas the "opposite side" is positive. A positive quantity divided by a negative one produces a negative result; hence, the tangent function is negative in Quadrant II.
-1 and 16/25
Negative one and sixteen twenty-fifths
= 3(a+b)
put a + b in brackets because your multiplying a and b three times
Add 2/3 with 5/6 and your answer will be 3/2
Using it's concept, it is found that the percent increase in the amount of iron per serving was of 50%.
<h3>What is the percentage increase of a value?</h3>
It is given by the increase divided by the initial value, and subtracted by 100%.
In this problem:
- The initial value is of 1.2 mg.
- The increase was of 1.8 mg - 1.2 mg = 0.6 mg.
Hence the percent increase is given by:
P = 0.6/1.2 x 100% = 50%.
