What is the product of 3 and the sum of 9 and x

i hope this is what you were looking for.

see attached graph

current in the circuit at time t is /, then the power delivered to the resistor is

step-by-step explanation:

jbankston is right, use thhe link and you should find the answer.

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.
