Dr. Pauline Boss is a family therapist, educator and researcher who is widely recognized for her groundbreaking research on what is now known as the theory of ambiguous loss. Dr. Boss is known as a pioneer in the interdisciplinary study...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

👉 Learn how to solve word problems with triangles. A word problem is a real-life situation which can be modelled mathematically. Word problems involving angles of elevation and depression, straight object leaning against a vertical...

👉 Learn how to solve for the unknown in a triangle divided internally such that the division is parallel to one of the sides of the triangle. The triangle proportionality theorem states that if a line is parallel to one side of a...

The video provides a lecture presentation on calculating the rate of absenteeism in businesses, discussing its importance and how it can be measured. The presenter offers two methods for calculating the rate, one for a single day and the...

In this episode, Jordan and Charlie explore two different ways the ponderosa pine and the trembling aspen deal with drought. In the face of adverse conditions, people might feel tempted by two radically different options—hunker down and...

The video provides a lecture presentation on plotting shapes using coordinates. The speaker establishes what coordinates are and explains how they show an exact position or location on a grid. The properties of shapes such as...

👉 Learn how to solve with the ratio of sides and angles of a triangle. Given the ratio of the sides of a triangle and the perimeter of the triangle, we can solve for the actual lengths of the triangle. Similarly, when the ratio of the...

Training a regression model to predict candidates' salaries using a linear regression algorithm.

Learn about compound interest. We will look at how to determine the final value, initial value, interest rate and years needed. We will investigate problems compounded continuously, daily, weekly, monthly, quarterly and yearly. These...

👉 Learn how to find the antiderivative (integral) of a function. The integral, also called antiderivative, of a function, is the reverse process of differentiation. Integral of a function can be evaluated as an indefinite integral or as...

In this eight-part series, Bill Janeway investigates the relationship between #venturecapital​ and technological #innovation​, and the interdependent roles of entrepreneurial firms, the mission-driven State and financial speculation in...

👉 Learn how to solve for an unknown variable in the interior angle of a polygon. A polygon is a plane shape bounded by a finite chain of straight lines. The interior angle of a polygon is the angle between two sides of the polygon. The...
