Jorin is building a model that shows how two different human body systems interact. He cuts a hole in a plastic tube, places a water filter in the hole, and connects a smaller tube directly to the filter. His model is shown below. Picture of a water filter

Jorin tests the model by running dirty water through the larger tube. Soon, the smaller tube begins to fill with clear water.

Which two body systems is Jorin most likely using his model to simulate?
A.
muscular and skeletal systems
B.
digestive and endocrine systems
C.
endocrine and nervous systems
D.
circulatory and urinary systems

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
