The correct term would be real numbers because whole numbers only belong in rational numbers. However, real numbers include BOTH ration and irrational numbers.
The period is equal to 2pi/n, where n is the coefficient of t. In this case pi/2. Therefore the period in this example is 4. Frequency is equal to 1/period. Hence the frequency for this problem is 1/4
- 1 1/10 + (-1 2/5)
- 1 1/10 + (-1 4/5)
-2 5/10
-2 1/2
The answer to this problem is b
X/50 = 20/100
its takes adding 30 to 20 to get to 50 so add 30 to 100 then its 130/100 (130 over 100) and then divide that and its 13 = 13%
i think its right dont hold it against me if im wrong
