To Check:TheSequence has a perfect linear model , perfect quadratic model or neither
Answer to Problem 63E
The sequence has a Quadratic Model
Explanation of Solution
Given:Write the first six terms of the sequence beginning with the given terms . Then calculate the first and the second differences of the sequence . State whether the sequence has a perfect linear model o, perfect quadratic model or neither
The Given ,
Then Let the first difference be denoted by d and the second differences denoted by S
Then
First differences
Second differences
Since the Second differences is same , the sequence has a Quadratic model

- Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lbarrow_forwardAn airplane flies due west at an airspeed of 428 mph.
