In an article in the College Mathematics Journal (Jan. 1987, 18:1), Arthur Segal proposed the following model for weight loss or gain:
where w(t) is a person’s weight (in pounds) after t days of consuming exactly C calories per day. Use this model to solve Problems 75–78.
78. Weight loss. A person weighing 175 pounds would like to lose 10 pounds during a 45-day period. How many calories per day should this person consume to reach this goal?

- please answer these questionsarrow_forward2. Consider the following statement: For each natural number n, (3.2n+2.3n+1) is a prime number. (a) Explore this statement by completing the table below for n = 2,3 and two additional values of n of your choosing (notice n = 1 has been completed for you). One of your rows should contain a counterexample. n 1 3.2 2.3 +1 3.212.31 + 1 = 13 prime or composite? prime 2 3 (b) Write a formal counterexample argument for the statement using the template fromarrow_forwardPlease ensure that all parts of the question are answered thoroughly and clearly.

- Selon une économiste d’une société financière, les dépenses moyennes pour « meubles et appareils de maison » ont été moins importantes pour les ménages de la région de Montréal, que celles de la région de Québec. Un échantillon aléatoire de 14 ménages pour la région de Montréal et de 16 ménages pour la région Québec est tiré et donne les données suivantes, en ce qui a trait aux dépenses pour ce secteur d’activité économique. On suppose que les données de chaque population sont distribuées selon une loi normale. Nous sommes intéressé à connaitre si les variances des populations sont égales.a) Faites le test d’hypothèse sur deux variances approprié au seuil de signification de 1 %.

Let U : R² → R³ be the linear transformation whose standard matrix is AT (the transpose of A). Let P: R³ → R³ be the linear transformation which first applies S and then applies U. Let Q: R² → R² be the linear transformation which first applies U and then applies S. Find the standard matrix of P and the standard matrix of Q. Clearly indicate which is which in your work.
