Average memory access time of cache
For this question, they've solved it using the formula AMAT = H1T1 + M1(H2T2 + M2 ...) and so on. However, since the question has directly given the hit time of the cache, I thought it'd be more appropriate to use the formula: ... ) + MissRate(MM)*(HitTime(Secondary))) So, which one is more appropriate and how would you differentiate between the two use cases?

Made Easy Test Series DBMS
Now given an instance of a schema we cant conclude whether A functionally determines B for the entire relation itself as $A\rightarrow B$ holds for this instance, but it might not hold for the entire schema. But we can conclude this for sure that B doesn’t functionally determine C. So the given 2 statements are not correct. Am I, right?

GATE GURU: TIME COMPLEXITY
In this question if we solve using logarithm we get time complexity of $g(n)>f(n)=h(n)$ But is taking $logarithm$ to find out the complexity always a safe way? I believe $NOT$. To support my claim I provide u with this link→ https://cs.stackexchange.com/ ... $logf(n)=O(log$ $g(n))$ So what is the approach to solve this problems to be $100\%$ sure about the ans?
