Question
While cramming for her MAT all find / exermination Sibalive learns a large number of proofs. At a time I weeks after the examination, the percentage of those proofs she is able to recall is given by the formula p(t) = 180 + 20e 1+ €0.5t According to this formulel a) the percentage of proces she is able to recall ato the time of writing the examination is by the percentage of proofs Four weeks after writing (1) E₂ a how many weeks after the examination will Sibaliwe be able to receill exactly 40% of the proofs? d) Applying Four iterations of the interval halvinela method to F(t) = pct) - 40, taking the initial approximations t₁ = 3 and ta = 5, yield the following apprexinations for the number of weeks after which Sibaline is able to recall exactly 40% of the proofs she memorized for the examination and to² = (21 t3 0.5t (3) 2167.90 = = she is able to recelll the examination is Alt S
