Answer:
You sense you want to find the dot product of vectors s = 7i - 5j and t = -i + 3j. To calculate the dot product, you multiply the corresponding components of the vectors and then sum them up.
s • t = (7 * -1) + (-5 * 3)
s • t = -7 - 15
s • t = -22
Therefore, the dot product of vectors s and t is -22.
