Aeolian dunes are sand dunes formed from wind depositing the sand in linear patterns whose cross sections are sinusoidal. The study of deposition patterns show that dunes around Grand Marais have dune ripples that crest 79 feet above Lake Superior and depressions that are 30 feet lower than the crest of the dune. The distance between one dune crest and the next dune crest is 60 feet. What is the trigonometric function that models the height of the dunes around Grand Marais?
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
