The following question tests your understanding of accretion. Mr. Dancer purchases a 5-percent corporate bond with 10 years to maturity at 80.
Look for horsepower (HP) ratings to compare the lifting power between garage door opener models. Ratings ranging from 1/2-horsepower to 1-1/2 horsepower are typical for residential models. If you have a sectional double-car garage door, a 1/2-horsepower motor should be sufficient, but a higher-power model will operate with less effort and less wear and tear on the motor.
Â½ HP: This size opener is the most popular out of the three and is recommended for single or double garage doors with average weight (ex: carriage style door). Again, this opener will only be efficient when the door is properly balanced and an opener with more horsepower will last longer.It is the second cheapest of the three with medium power. 3/4 HP: Oversized, large, and heavy doors will need an opener with Â¾ horsepower (ex: wood doors).This is recommended by most due to the fact that it will last the longest and provide the best long-term outcome.gain, this opener will only be efficient when the door is properly balanced and an opener with more horsepower will last longer.
