Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Not long ago, a popular car magazine raced a Dodge Viper SRT- 10 on an airport runway to see how fast it could go. They used GPS to record how many seconds the Dodge Viper SRT-10 took to reach different speeds as it accelerated down the track. That data is shown below. time (sec) speed (mph) 4.4 60 9.6 100 12.5 116.8 19.5 142.1 24.1 150 25.6 152.1 31.4 159.7 a) Use logarithmic regression to find a logarithmic function that best fits this data. Round each value to at least three decimal places. y = b) Use logistic regression to find an logistic function that best fits this data. Round each value to at least three decimal places. Y =

A state patrol officer saw a car start from rest at a highway on-ramp. She radioed ahead to another officer 26 mi along the highway. When the car reached the location of the second officer 21 min later, it was clocked going 60 mi/hr. The driver of the car was given a ticket for exceeding the 60 mi/hr speed limit. Why can the officer conclude that the driver exceeded the speed limit? Select the correct answer below and fill in the answer box to complete your choice. (Type an integer or decimal rounded to the nearest hundredth as needed.) O A. The officer can conclude the driver exceeded the speed limit because, by the Mean Value Theorem, at some time c, the car was travelling at a speed of miles per hour. O B. The officer can conclude the driver exceeded the speed limit because, by the Extreme Value Theorem, at some time c, the car was travelling at a speed of miles per hour. O C. The officer can conclude the driver exceeded the speed limit because, by Rolle's Theorem, at some time c,…

The speed of a runner increased during the first three seconds of a race. Her speed at half-second intervals is given in the table. Find lower and upper estimates for the distance that she traveled during these three seconds. The answer to this problem requires that you enter the correct units.
