Wage Incentive Plan, A producer of a perishable product offers a wage incentive to drivers of its trucks. A standard delivery takes an average of 20 hours. Drivers are paid at the rate of $10 per hour up to a maximum of 20 hours. There is an incentive for drivers to make the trip in less (but not too much less) than 20 hours. For each hour under 20, the hourly wage increases by $2.50. (the $2.50 – per – hour increase in wages applies for fractions of hours. That is if a trip takes 19.5 hours, the hourly wage increases by 0.5 x $2.50, or $1.25.) Determine the function w = f(n), where w= the hourly wage (in dollars) and n equals the number of hours to complete the trip.
For times t >0 in seconds, a police car is patrolling a local street. The position along the straight, flat road is given in meters by the function P t( )=25t. Directly ahead of the police car, a bank robber’s getaway car begins to speed up to leave the scene of the crime. The getaway car’s position along the road is given in meters by the function G t( )= + 75 2 5t 2 . . Graph the functions P t( ) and G t( ) on the same set of axes. What conclusion can you draw? Does the police car catch the getaway car? Determine the time at which the police car intersects the getaway car, or determine how close the police car gets to the getaway car before the bank robber evades capture
Rita discovered that a lab thermometer in her Chemistry class is not accurate. She created the table to show the relationship between x, the thermometer’s temperature reading, and y, the actual temperature.
Which equation represents the relationship between x and yshown in the table?
y = −x
y = 4x
y = x + 4
y = x + 1
