<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.
Work:
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.

If y is the normal number of sweets then the normal number plus 40% equals 42.
y + .4y = 42
1.4y = 42
y = 42/1.4 = 30 .
Hope this helps!
Answer:
x = -5, and x=4
Step-by-step explanation:
You can factor the quadratic out by factoring to get
(x+5)(x-4) = 0
then solve for x
x = -5, 4
Multiplying exponents of the same base is basically adding up the exponents. Make sure the base the same which it is.
y^4 x y^6 = y^10
Answer:
r = 3
Step-by-step explanation:
− 3 ( 6 r + 2 ) + 5 ( r + 1 ) = − 40
- 18r - 6 + 5 ( r + 1 ) = - 40
- 18r - 6 + 5r + 5 = - 40
-13r - 1 = - 40
-13r = - 39
r = 3
