Question 3: In reviewing the model, Mr. Simon realizes that the quantities demanded and sold depend on the selling price of the pies. The pie's demand equation is given by: Pies Demanded \( =50.4-4.3 \times \) Pie Price. a. Calculate the new values of the financial results. What has happened to the new profit? b. Implement these calculations in a new spreadsheet labeled Sheet_Q3.

In the figure, \( \angle A C B=\angle C B D=90^{\circ} \), \( \angle B A C=57^{\circ}, \angle B D C=62^{\circ} \) and \( A B=12 \mathrm{~cm} \) Calculate (i) the length of \( B C \), (ii) the length of \( B D \).

Являются ли параллельными пліскости \( A B B_{1} \) и \( C E E_{1} \) проходяшие через вершины правныьной шестиугольной призмы \( A B C D E F A_{1} B_{1} C_{1} D_{1} E_{1} F_{1} \) ?

The radioactive substance uranium- 240 has a half-life of 14 hours. The amount \( A(t) \) of a sample of uranium-240 remaining (in grams) after \( t \) hours is given by the following exponential function. \( A(t)=1500\left(\frac{1}{2}\right)^{\frac{t}{14}} \) Find the initial amount in the sample and the amount remaining after 30 hours. Round your answers to the nearest gram as necessary. Initial amount: 1500 grams

5. \( \frac{5 \frac{4}{3}}{4}=\square \)

atomic radius of hydrogen is 37: \( \begin{array}{ll}\text { a) Pecometer } & \text { b) Manometer } \\ \text { c) Angstrom } & \text { d) Micrometer }\end{array} \)
