Final answer:
The number of words memorized in the first 8 minutes is 114.
Step-by-step explanation:
The rate of memorizing in words per minute can be represented by the equation where r is the memory rate in words per minute. To find out how many words are memorized in the first 8 minutes, we need to plug in the value of 8 for t in the equation.
r = t^2 + 5t + 10
r = (8)^2 + 5(8) + 10
r = 64 + 40 + 10
r = 114
Therefore, 114 words are memorized in the first 8 minutes.
