Empirical data are gathered from experiments. This does not hold true for all species at all times. But the only way to know a certain datum for a certain specie at a certain situation, you do an experiment. However, theoretical data is more on the theory or concept of the situation. It formulates a general equation that could as much as possible hold true to all.
Therefore, this data is empirical.
The answer is A.
-16t² + 32t + 128 = 0
-16t² + 64t - 32t + 128 = 0
-16t(t - 4) - 32(t - 4)
(-16t - 32)(t - 4) = 0
-16t -32 = 0 t - 4 = 0
-16t = 32 t = 4
t = -2
t = -2 and t = 4 are the values that makes S = 0.
Yes, because if you apply either of these values alone, S will be 0.
There are mainly six trigonometric functions for right angle triangle which are
- sinФ
- cosФ
- tanФ
- cosecФ
- secФ
- cotФ
All of these can be expressed in the form of sinФ and cosФ as following:
- sinФ = sinФ
- cosФ = cosФ
- tanФ = sinФ/cosФ
- cosecФ = 1/sinФ
- secФ = 1/cosФ
- cotФ = cosФ/sinФ
This angle Ф is shown in the attached drawing in a right angle triangle drawn within a circle which is the given angle. Right angle is mentioned as "90".
1,000 is independent because nothing it changing it.
150x is dependent because 150 relies on the variable x.
