Near the end of 2020, we got some puzzling but good news: COVID-19 fatality rates have been dropping. Here are a few factors that might help explain why we’re seeing this trend.

The buy now pay later model has surged in popularity during the pandemic. Max Levchin, founder and CEO of Affirm, discusses the impact of rising rates and a stock market pullback on his business and the broader entrepreneurial community.

👉 Learn how to take the derivative of a function. Learn how to find the derivative of a function using the chain rule. The derivative of a function, y = f(x), is the measure of the rate of change of the function, y, with respect to the...

In this short video we will answer a standardized math test question where we are asked to identify the greatest rate of change from 4 multiple choice options. We will review each option identify the slope which is the rate of change. ...

This video lesson is an introduction to slope. Students learn that slope is a rate comparing the rise, change in y, over run, the change in x. Practice is embedded within the lesson to check for understanding.

Interest rate hikes are often portrayed as a bad thing for consumers, but when it comes to investing, they could present opportunities for profit. Here's what you need to know.

This video provides an explanation and examples of interpreting gradients as rates of change. The speaker discusses how the gradient of a line can represent the rate of change, with steeper lines indicating a greater rate of change. They...

This video explains the concept of average and instantaneous rates of change and their significance in various fields such as science, stock markets, and space missions. It discusses how to calculate the rate of change using the gradient...

👉 Learn how to find the rate of change from a table of values. The rate of change of a set of data listed in a table of values is the rate with which the y-values are changing with respect to the x-values. To find the rate of change from...

👉 Learn how to find the rate of change from word problems. The rate of change is the rate at which the the y-value is changing with respect to the change in x-value. To determine the rate of change between two points, we just need to...

Near the end of 2020, we got some puzzling but good news: COVID-19 fatality rates have been dropping. Here are a few factors that might help explain why we’re seeing this trend.

Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satellite data.



If the...

Rates of teen suicide are rising, and rates for girls are higher than any time in the last 40 years. There are a number of ways to address this problem, but why aren't we using evidence based approaches to the problem?

A new study shows that sea level is rising at a speed that is faster than the previous 27 centuries. Sea level rose at a rate of 1.4 millimeters per year between 1900 and 2000 while the current rate is 3.4 millimeters per year, according...

Pupil outcome: I can calculate the positive rate of change (gradient) from a graph. Key learning points: - Graphs can be described by looking at how quickly they rise. - The amount y changes when x increases by one is the rate of change...

Earth’s global sea levels are rising – and are doing so at an accelerating rate. Waters in the ocean are expanding as they absorb massive amounts of heat trapped by greenhouse gases in Earth’s atmosphere. Glaciers...

In this lesson, students learn how to interpret the rate of change of a line of best fit by calculating the slope. They review the concept of slope as the ratio of change in Y to change in X, also known as rise over run. The lesson...
