Mr. stephenson drives his car from dallas to town x, a distance of 437 km. the trip takes 7.27 hours. what is the average speed of this trip in meters per second (m/s)? a. 16.7 m/s b. 8.35 m/s c. 60.1 m/s d. 19.7 m/s

Average speed = (distance covered) / (time to cover the distance).

Distance covered = 437 km = 437,000 meters

Time to cover the distance = (7.27 hrs) x (3600 sec/hr) = 26,172 seconds

Average speed = (437,000 meters) / (26,172 seconds)

Average speed = 16.7 m/s

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
