Question

Participants in a psychology expirement

were able to memorize an average of M Words in

T minutes, where M is -0.00lt3 and T is 0.1t2 Find the

average

number of words memorized in 10min.

Answer 1

11 words

Explanation:

The question is poorly formatted.

The right relationship between M and t is given as:

M = −0.001t³ + 0.1t²

Required

Solve for M when t = 10

To do this, substitute 10 for t

So,we have:

M = −0.001t³ + 0.1t²

M = -0.001 * 10³ + 0.1 * 10²

M = -0.001 * 1000 + 0.1 *100

M = 1 + 10

M = 11
