The time at which the depth of the ocean at a given location is at its maximum is known as high tide, while the time at which the depth of the ocean at a given location is at its minimum is known as low tide. A measurement taken at a recording station at 10 a.m. determined the depth at high tide to be 2.25 feet. At 10 p.m., the depth of low tide was measured to be 0.5 feet. This pattern was seen to repeat each day. Part A: What type of function models the depth of the water at time t hours after high tide? Part B: Find a model to determine the depth of the water, d(t), at any given time t.
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.
