Answer:
2321 ft.
Step-by-step explanation:
When Cai traveled from New Orleans to the Ozark Mountains in Arkansas the elevation changes from 7 ft below sea level to 2314 ft above sea level.
If we consider the elevation below sea level as negative and the elevation above sea level as positive, then the elevation changes from - 7ft to +2314 ft.
Therefore, the increment of elevation is by [2314 - (- 7)] = 2321 ft. (Answer)
Answer:
a(n) = 

Step-by-step explanation:
The given expression is in the form of the explicit formula of a geometric sequence.
f(n) = 
Where 'a' = First term of the sequence
r = common ratio
Recursive formula of a geometric sequence is,
a(n) = 
a(n) = 
Where, 
So the recursive formula will be a(n) = 
Answer:
A. Height is input, Weight is output
Step-by-step explanation:
We are given the statement,
"Weight is a function of height".
As we know,
<em>In a function of the form
, the input variable is 'x' and the output variable is 'y'.</em>
If we write the given statement in the form
, we get,

This means that the input variable is 'Height' and the output variable is 'Weight'.
Hence, option A is correct.
Answer:

Step-by-step explanation:
Given

Required
Determine the inverse function
Start by replacing f(x) with y

Swap the positions of y and x

Make y the subject: <em>Add 4 to both sides</em>


Make y the subject: <em>Divide through by 2</em>
<em></em>
<em></em>
<em></em>
<em></em>
<em></em>
Replace y with f-1(x)

Yes it is linear since it's in the standard form Ax+By = C
A = 2
B = -8
C = 16
