Answer:
The average of the two boys' points is p=3 is 19.4 points~
Step-by-step explanation:
What you need to do is that you plug p=3 into the expression [(5.4p+5)+(8+3.2p)]/2 and you have:[(5.4*3+5)+(8+3.2*3)]/2= (21.2+ 17.6)/2= 38.8/2= 19.4
The formula for the growth rate is given by
Now when b is greater than 1 , then it is increasing function
and when b is less than 1 , then it is decreasing function.
Now in the function
here value of b is 0.88 , which is less than 1 , so it is decreasing function
And decay rate is given by
1-r = 0.88
Subtract 1 from both sides
-r = 0.88-1
-r = -0.12
r = 0.12
or r= 12%
It means it is decreasing at a rate of 12%
Hence Option C is correct
C.The price of the boat decreases by 12% every year.
