Answer:
It's position at time t = 5 is 593.
Step-by-step explanation:
The velocity v(t) is the integral of the acceleration a(t)
The position s(t) is the integral of the velocity v(t)
We have that:
The acceleration is:
![a(t) = 24t + 2](https://tex.z-dn.net/?f=a%28t%29%20%3D%2024t%20%2B%202)
Velocity:
![v(t) = \int {a(t)} \, dt = \int {24t + 2} \, dt = 12t^{2} + 2t + K](https://tex.z-dn.net/?f=v%28t%29%20%3D%20%5Cint%20%7Ba%28t%29%7D%20%5C%2C%20dt%20%3D%20%5Cint%20%7B24t%20%2B%202%7D%20%5C%2C%20dt%20%3D%2012t%5E%7B2%7D%20%2B%202t%20%2B%20K)
K is the initial velocity, that is v(0). Since V(0) = 13, K = 13
Then
![v(t) = 12t^{2} + 2t + 13](https://tex.z-dn.net/?f=v%28t%29%20%3D%2012t%5E%7B2%7D%20%2B%202t%20%2B%2013)
Position:
![s(t) = \int {s(t)} \, dt = \int {12t^{2} + 2t + 13} \, dt = 4t^{3} + t^{2} + 13t + K](https://tex.z-dn.net/?f=s%28t%29%20%3D%20%5Cint%20%7Bs%28t%29%7D%20%5C%2C%20dt%20%3D%20%5Cint%20%7B12t%5E%7B2%7D%20%2B%202t%20%2B%2013%7D%20%5C%2C%20dt%20%3D%204t%5E%7B3%7D%20%2B%20t%5E%7B2%7D%20%2B%2013t%20%2B%20K)
Since s(0) = 3
![s(t) = 4t^{3} + t^{2} + 13t + 3](https://tex.z-dn.net/?f=s%28t%29%20%3D%204t%5E%7B3%7D%20%2B%20t%5E%7B2%7D%20%2B%2013t%20%2B%203)
What is its position at time t=5?
This is s(5).
![s(t) = 4t^{3} + t^{2} + 13t + 3](https://tex.z-dn.net/?f=s%28t%29%20%3D%204t%5E%7B3%7D%20%2B%20t%5E%7B2%7D%20%2B%2013t%20%2B%203)
![s(5) = 4*5^{3} + 5^{2} + 13*5 + 3](https://tex.z-dn.net/?f=s%285%29%20%3D%204%2A5%5E%7B3%7D%20%2B%205%5E%7B2%7D%20%2B%2013%2A5%20%2B%203)
![s(5) = 593](https://tex.z-dn.net/?f=s%285%29%20%3D%20593)
It's position at time t = 5 is 593.
Answer:
13
Step-by-step explanation:
Step-by-step explanation:
There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot. These are referred to as ratios since they can be expressed in terms of the sides of a right-angled triangle for a specific angle θ.
Area of the rectangle is 2*6=12 in^2
12 could be = 1*12 or 2*6 or 3*4
P could be 2*(1+12)=2*13=26
2*(2+6)=2*8=16
2*(3+4)=2*7=14
the answer is 24 in (c)
