Question 23 Memorizing. The rate of memorizing information initially Not yet answered increases. Eventually, however, a maximum rate is reached, Marked out of 1.00 after which it begins to decrease. Flag question (in words Memory rate per minute) 0 10 Time (in minutes) Suppose that in a memory experiment the rate of mem- orizing is given by M'(t) = -0.009t2 + 0.2t, where M'(t) is the memory rate, in words per minute. How many words are memorized in the first 10 min (Give the numerical answer only) wordsQuestion 25 Not yet answered A Marked out of 1.00 3 =-X+3x- 1 2 Flag question -2 Consider (-x3 + 3x - 1) dx. Evaluate the integral. Select one: O a. -2.25 O b. 2.25 O C. 1.25 O d. -1.25Question 24 Physics. A particle starts out from the origin. Its Not yet answered velocity, in miles per hour, after t hours is given by Marked out of 1.00 v(t) = 312 + 2t. How far does it travel from the 2nd hour through the Flag question 5th hour (from t = 1 to t = 5)? (Give the numerical answer only) miles
