Answer: freemasonry is Being a Mason is about a father helping his son make better decisions; a business leader striving to bring morality to the workplace; a thoughtful man learning to work through tough issues in his life.
Explanation:
When a psychologist simply records the relationship between two variables without manipulating them, it is called a correlational study.
The observed relationship does not by itself reveal which variable causes the other. This is the directionally problem. Also, the relationship may be due to a third variable controlling both of the observed variables.
I think the answer is B. 10D
Answer
given,
a = 2 t - 10
velocity function
we know,
![\dfrac{dv}{dt}=a](https://tex.z-dn.net/?f=%5Cdfrac%7Bdv%7D%7Bdt%7D%3Da)
![\dfrac{dv}{dt}=(2t-10)](https://tex.z-dn.net/?f=%5Cdfrac%7Bdv%7D%7Bdt%7D%3D%282t-10%29)
integrating both side
![\int dv =\int (2t -10) dt](https://tex.z-dn.net/?f=%5Cint%20dv%20%3D%5Cint%20%282t%20-10%29%20dt)
v = t² - 10 t + C
at t = 0 v = 3
so, 3 = 0 - 0 + C
C = 3
Velocity function is equal to v = t² - 10 t + 3
Again we know,
![\dfrac{dx}{dt}=v](https://tex.z-dn.net/?f=%5Cdfrac%7Bdx%7D%7Bdt%7D%3Dv)
![\dfrac{dx}{dt}=(t^2-10t + 3)](https://tex.z-dn.net/?f=%5Cdfrac%7Bdx%7D%7Bdt%7D%3D%28t%5E2-10t%20%2B%203%29)
integrating both side
![\int dx =\int (t^2-10t + 3)dt](https://tex.z-dn.net/?f=%5Cint%20dx%20%3D%5Cint%20%28t%5E2-10t%20%2B%203%29dt)
![x = \dfrac{t^3}{3}- 10\dfrac{t^2}{2} + 3 t + C](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7Bt%5E3%7D%7B3%7D-%2010%5Cdfrac%7Bt%5E2%7D%7B2%7D%20%2B%203%20t%20%2B%20C)
now, at t= 0 s = -4
![-4 = \dfrac{0^3}{3}- 10\dfrac{0^2}{2} + 0 + C](https://tex.z-dn.net/?f=-4%20%3D%20%5Cdfrac%7B0%5E3%7D%7B3%7D-%2010%5Cdfrac%7B0%5E2%7D%7B2%7D%20%2B%200%20%2B%20C)
C = -4
So,
![x = \dfrac{t^3}{3}- 10\dfrac{t^2}{2} + 3 t-4](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7Bt%5E3%7D%7B3%7D-%2010%5Cdfrac%7Bt%5E2%7D%7B2%7D%20%2B%203%20t-4)
Position function is equal to ![x = \dfrac{t^3}{3}- 10\dfrac{t^2}{2} + 3 t-4](https://tex.z-dn.net/?f=x%20%3D%20%5Cdfrac%7Bt%5E3%7D%7B3%7D-%2010%5Cdfrac%7Bt%5E2%7D%7B2%7D%20%2B%203%20t-4)
