Answer:

Step-by-step explanation:
step 1
Calculate the area of the shaded portion

step 2
Calculate the area of the unshaded portion

step 3
Find the difference of the areas

(2,0,-1,-1,-2) that is the domain from what I remember. Hope that help
The area of a circle with radius r is πr². So you need to find r such that
πr² = 56π
⇒ r² = 56
⇒ r = √56 = 2√14

Answer:
Option D [
] in the list of possible answers
Step-by-step explanation:
For this problem you are supposed to use a calculator that allows you to do an exponential regression. There are many tools that can help you with that, depending on what your instructors has assigned for your class.
I am showing you the results of a graphing tool I use, and which after entering the x-values and the y-values in independent "List" forms, when I request the exponential regression to fit the data, I get what you can see in the attached image.
Notice that the exponential of best fit with my calculator comes in the form:

with optimized parameters:

Notice as well that since:

the exponential best fit can also be written:

and this expression is very close to the last option shown in your list of possible answers
