a. Write an expression (in terms of s) to represent the number of radians Kristin has swept out since the ride started. Preview b. Write an expression (in terms of s) to represent Kristin's height above the center of the Ferris wheel measured in radius lengths. Preview c. Write an expression (in terms of s) to represent Kristin's height above the center of the Ferris wheel measured in meters. Preview
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.
![Kristin boards a Ferris wheel at the 3-o'clock and rides the Ferris wheel for one full rotation (as shown below). The radius of the Ferris wheel is
12 meters. Let s represent the varying number of meters Kristin has traveled along the circular path since the ride started.
