The inches of rainfall in the rainforest is represented by the function f(x) = 3(x-2)+ 4. What is the average rate of change between the 2nd year and the 6th year?

The average rate of change of rainfall in the rainforest between 2nd year and 6th year = 3 inches

Step-by-step explanation:

Given function representing inches of rainfall:

To find the average rate of change between the 2nd year and the 6th year.

Solution:

The average rate of change between interval is given as :

For the given function we need to find the average rate of change between 2nd year and 6th year.

So, we have:

Thus, average rate of change will be:

⇒

⇒

⇒

Thus, the average rate of change of rainfall in the rainforest between 2nd year and 6th year = 3 inches

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
