<h3>
Answer:</h3>
- The decrease is Linear.
- The component will cost $84.59 in 3 years
- The decline in price is Exponential.
<h3>
Step-by-step explanation:</h3>
Question 1:
In this question, it's asking you if the decreasing rate is linear or exponential.
The decreasing rate would be <u>linear</u>, due to the fact that it is decreasing at a constant rate of 11%. The decreasing rate doesn't change, which makes this linear.
Question 2:
In this question, it's asking you what would the component's cost be in 3 years if it started off at $120.
To find this, we're going to need multiply the price by -.11, and then subtract to get the price. We would repeat this until we reach 3 years.

Question 3:
In this question, it asks if the decline in price is linear or exponential.
The decline in price would be <u>exponential</u>, due to the fact that the decrease in price is not always the same, since it changes every year. The price doesn't decrease at the same price each year. As you see from question 2, the change in price is not the same each year.

Yes because if you multiply it by anything it will always be zero
Answer:
20hours
Step-by-step explanation:
Jack can complete the painting in 30hours. The fraction he can paint per hour is thus 1/30
Trainee can complete the painting in 45hours, the fraction he can paint per hour is 1/45
If they are working together, the fraction that can paint in an hour is :
1/45 + 1/30 = 5/90 = 1/18
Now we know they can paint 1/18 of the room in an hour, the number of hours needed to completely paint the room is thus 1/1/18 = 18 hours
Rounding up answer to the nearest tenth is 20hours
