Answer: C. 1/4
Step-by-step explanation
Given
![F(t)=2\cdot(1)/(2^(3t))](https://img.qammunity.org/2023/formulas/mathematics/college/ag37ayuv2lpmq07yrajsrdo75guioavyes.png)
As we are asked to find F(1), then we have to substitute 1 over t:
![F(1)=2\cdot(1)/(2^(3(1)))](https://img.qammunity.org/2023/formulas/mathematics/college/6zirqwg6yvbzniy98wxc09gidyporqtq51.png)
By multiplying the expression in the exponent we get:
![F(1)=2\cdot(1)/(2^3)](https://img.qammunity.org/2023/formulas/mathematics/college/cntgbb9vomvlbimvnmccfgc602xh0zmxnx.png)
We can rewrite this expression as follows as we have 2 elevated to the third power:
![F(1)=(2)/(2\cdot2\cdot2)](https://img.qammunity.org/2023/formulas/mathematics/college/z5u75f5h32ex3yi18zs7l73wnpouzz8dhu.png)
Simplifying;
![F(1)=(1)/(2\cdot2)](https://img.qammunity.org/2023/formulas/mathematics/college/xx9edx7ixycxyqgz1qz9av4q3h15o8qt51.png)
![F(1)=(1)/(4)](https://img.qammunity.org/2023/formulas/mathematics/college/6qi7xjrsq8dhyg7geigf3qnm1pm4ilh6kf.png)
