The answer is: D - Both A and C.
The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s
<h3>
Velocity function </h3>
Given the equation for the position of the mouse expressed as:
![x(t)=pt^2+qt\\](https://tex.z-dn.net/?f=x%28t%29%3Dpt%5E2%2Bqt%5C%5C)
The velocity of the particle is expressed as:
![v(t)=2pt+q](https://tex.z-dn.net/?f=v%28t%29%3D2pt%2Bq)
Given that p = 0. 40 m/s and q = -1. 10 m/s, the equation will become:
![v(t)=2(0.4)t-1.10\\v(t)=0.8t - 1.10](https://tex.z-dn.net/?f=v%28t%29%3D2%280.4%29t-1.10%5C%5Cv%28t%29%3D0.8t%20-%201.10)
If the time is <em>t = 1.0 s, the velocity will be:</em>
![v(1) = 0.8 - 1.10\\v(1) = -0.3m/s](https://tex.z-dn.net/?f=v%281%29%20%3D%200.8%20-%201.10%5C%5Cv%281%29%20%3D%20-0.3m%2Fs)
Similarly if t = 4.0ssec, hence:
![v(4) = 3.2 - 1.10\\v(4) = 2.1m/s](https://tex.z-dn.net/?f=v%284%29%20%3D%203.2%20-%201.10%5C%5Cv%284%29%20%3D%202.1m%2Fs)
The average speed between t = 1.0 s and t = 4.0 s will be 2.1+0.3 which is 2.4m/s

Complete question
<em>A mouse runs along a baseboard in your house. The mouse's position as a function of time is given by x(t)=pt 2+qt, with p = 0.40 m/s2and q = -1.10 m/s . Determine the mouse's average speed between t = 1.0 s and t = 4.0 s. I have tried everything and the answer is not 0.40 m/s</em>
Answer: D
Explanation because there is no point in having to know other skills. that don't evolve your job.
Answer:
1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
Explanation:
2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.
