1. The member of polio cases reported each year worldwide has dramatically decreased. In the year 2000, there were about 4000 cases of polio. In the year 2008, there were
1700 cases of polio reported.
(a) (3 points) Find an exponential function f(t) = ab' which models the number
of reported polio cases each year since the year 2000. You can round your value
of b to 3 decimal places.
(b) (3 points) Use your function to predict the number of polio cases worldwide in
the year 2022
(c) (3 points) Use your function to predict the year in which there will be only 1
case of polio worldwide.

step-by-step explanation:

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

-1, -2, -3, -4, -6

step-by-step explanation:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
