- hello what sort of calculator did you use? i am using ti 84 and ti 89 still not getting the answer even when i use you numbers. i am a bit confused about that.In the last column in the data table, it says that it's about voltage(v) divided by current(A) is equal to ohms so V/A = ohms. So if it's V/A and if you divide them to get the slope it's (y2-y1)/(x2-x1) then shouldn't V be the y value and A be the x value? And can you also try to use a line of best bit instead of drawing the line through each dot?The graph below shows the current that flows through a device called a diode at different voltages. Instead of the numbers presented on this graph, consider a diode for which current varies with voltage according to the equation I = V11.9. Hint: Plot this equation on your calculator. a. What is the resistance of the diode when a potential difference of 0.59 volts is placed across it? Include units in your answer. b. What is the resistance of the diode when 0.72 volts is placed across it? Include units in your answer.
- The active area of the amd ryzen 5950x processor in high end computers today has about 19.2 billion transistors (transistors are semiconductor device that control electronic processes).

What are the dimensions of one transistor on the die, assuming that all of the area across the die is transistors and each is a square?I have tried this one multiple times and got the following answers: 1.24E13, 1.24E14, 2.84E27, 5.67E26.

(The execution times of all other types of instructions remain unchanged.) If the upgrade decreases the execution time of a particular program to 0.7 times what it was originally, what fraction of the original execution time must have been spent on executing floating point instructions?
