f(x)=2,459(0.92)^t
Using the information given above, complete the following statements. The percent change is %. The percent change represents .
f(x)=2,459(0.92)^t
Given equation is an exponential function and in the form of f(x) = a(1-r)^x
Where 'a' is the initial population
'r' is the decay rate
'x' is the time
f(x) = a(1-r)^x
Given function is f(x)=2,459(0.92)^t
1 - r = 0.92
r = 1 - 0.92
r = 0.08
r= 0.08 %
Percentage change = 0.08%
Percentage change represents the decay rate.
Answer: 1) 
2) 
3) 13, 4) 10.
Step-by-step explanation:
Since we have given that
So, we need to find :
1) a + b is given by
2) 2a+3b is given by
3) |a| is given by
4) |a-b| is given by
Hence, 1) 2) 3) 13, 4) 10.
Total Value =$23,000
Time = 10 february to 10 august = 6 months
And
Rate of discount = 9% =0.09
Now we have to find the discount on the note
So we multiply the amount , time and rate
but time should be in years
So 6 months = 6/12 years = 0.5 years
So
Discount = 23,000 * 0.5 * 0.09 = 1035
Hence total Discount = $1035
We have 3*4+2, or 14, by substituting in for x.
