Answer:
The value of r is 0.451
The percentage decrease is about 45.1%
Step-by-step explanation:
The given exponential function is 
Using the exponent rule, 
Now the value of 
Thus, we can rewrite the function as
Therefore, the function in form 
The value of r is 0.451
The percentage decrease is about 0.451 ×100 = 45.1%
Don’t understand this kind of math
So, basically you have to get a data set, which you can almost freely choose the subject of. Then, you must get a visual representation, like a bar graph, with all of the data that you use. Make sure you label!! Lastly, all you have to do is answer all of the questions in part 3. Those include numbers 1, 2, 4, and 5. for number 3, you are able to choose between letters a and b, depending on either you or your subject. Then you just turn it in. Sorry if it was a vague description, but it's a pretty straightforward project. Hope it helped a little bit!!
A.3x+5=65
-5 -5
subtract 5 from 5, subtract 5 from 65 to get 3x=60
B. 3x=60
divide 3x by 3,divide 60 by 3 to get x by itself
x=20
