The document discusses the definite integral and how to estimate distances traveled from a velocity-time graph. It includes a table of velocity values and asks the reader to (1) sketch the velocity-time graph, (2) estimate the lower and upper distances traveled in 5 seconds, (3) estimate the actual distance traveled, and (4) represent the lower estimate as a shaded region on the graph. The document also asks why we began by looking at the picture of rectangles.
The document discusses derivatives and second derivatives of functions. The first derivative f' of a function f assigns values to inputs where f is differentiable. The second derivative f'' can then be calculated by taking the derivative of the first derivative function f' and defines f''(a) using a formula involving limits.
The document describes the process for a pre-test on polynomials and factoring. It states that students will spend 20 minutes individually completing the pre-test without calculators. They will then spend 10 minutes discussing the results in groups of three. Each group will submit one sheet of paper with their best answers. Remaining time will be used to go over unanswered questions as a class. The actual test on the material will take place the next day.

The problem asks to find the length of DC given that AB is 3 units long, BC is 4 units long, and DE is 10 units long. The midpoint formula is used to find the coordinates of point B given that the midpoint M of AB is (1/2, 6) and the coordinates of A are (3, 7).
This document provides instructions for students to transition from Investigation 1 to Investigation 2 in their science class, suggests making graph paper if none is available, and assigns homework of questions 1 through 6 on pages 207 to 209 for their teacher, Mrs. Karras, which is due tomorrow.

It also covers stretches and compressions along the x and y axes depending on whether parameters a or b are greater than, less than, or between 0 and 1.
A car leaves Winnipeg traveling east or west on a highway at 35 miles per hour. The document discusses using integrals to calculate how far the car is from Winnipeg after 4 hours, taking into account the car's average speed and time traveled. It provides some examples of potential velocity functions that could model the car's motion and notes the driver's poor driving abilities may impact the results.
The document discusses translations of graphs and functions. It provides examples of translating graphs by sliding them along the x-axis. It asks the reader to write equations representing translations of sine graphs based on given functions. It also asks the reader to write one function in terms of another after a translation. Homework assigned is to complete exercise 7 and encourages studying.
The document discusses experimental and theoretical probability. Experimental probability is determined by repeated testing and observing results, calculated as the number of times an event occurred divided by the total number of tests. Theoretical probability is calculated under ideal circumstances based on possible outcomes. For a family with 3 children, the theoretical probability of having 2 girls can be calculated as the number of ways to have 2 girls (3 combinations) divided by the total possible outcomes (8 combinations). An example is also given of simulating a binomial experiment using a calculator to determine the probability of getting exactly 2 heads when flipping 3 coins 40 times.
In a family with 3 children, the probability that 2 of the children will be girls can be calculated as follows:
There are 3 children and each child can be either a boy or a girl. So there are 2 possible outcomes for each child. Using the fundamental principle of counting, there are 2 * 2 * 2 = 8 possible combinations of boys and girls. Out of these 8 combinations, 3 combinations will have exactly 2 girls. Therefore, the probability that 2 of the 3 children will be girls is 3/8.
