1/3 and 2/3 is the answer I think I’m not 100% sure
Answer:
R 694.4
Explanation:
simple interest =
→
→ R 134.4
where p refers to principal, r refers to rate, t refers to time.
total money:
invested money + simple interest
R 134.4 + R 560 → R 694.4
Laplace transform of f(t) is
![L[f(t)] = \frac{1}{s-(a+b)}-\frac{1}{s-(a-b)}](https://tex.z-dn.net/?f=L%5Bf%28t%29%5D%20%3D%20%5Cfrac%7B1%7D%7Bs-%28a%2Bb%29%7D-%5Cfrac%7B1%7D%7Bs-%28a-b%29%7D)
Step-by-step explanation:
Given that 
Also, 
Simplyfing,



Now, we know

Therefore,
![L[f(t)] =L[ \frac{e^{(a+b)t}}{2}- \frac{e^{(a-b)t}}{2} ]](https://tex.z-dn.net/?f=L%5Bf%28t%29%5D%20%3DL%5B%20%5Cfrac%7Be%5E%7B%28a%2Bb%29t%7D%7D%7B2%7D-%20%5Cfrac%7Be%5E%7B%28a-b%29t%7D%7D%7B2%7D%20%5D%20)
![L[f(t)] = \frac{1}{s-(a+b)}-\frac{1}{s-(a-b)}](https://tex.z-dn.net/?f=L%5Bf%28t%29%5D%20%3D%20%5Cfrac%7B1%7D%7Bs-%28a%2Bb%29%7D-%5Cfrac%7B1%7D%7Bs-%28a-b%29%7D)
