Please find the complete question in the attached file.
Using formula:
So,
when it becomes
so plug the value into the formula

Using an exponential function, it is found that f(5.5) = 19.8.
<h3>What is an exponential function?</h3>
An exponential function is a function in which the growth rate is a percentage, modeled by:

In which:
f(3.5) = 25 means that:


f(8.5) = 14 means that:

Hence:


![b = \sqrt[5]{\frac{14}{25}}](https://tex.z-dn.net/?f=b%20%3D%20%5Csqrt%5B5%5D%7B%5Cfrac%7B14%7D%7B25%7D%7D)


Hence, the function is given by:

Then, when x = 5.5:

Answer: $6</h3>
Explanation:
To take 10% of anything, move the decimal point 1 spot to the left.
The number 60.0 will become 6.00 or simply 6.
In other words, we chop off the 0 at the end go from 60 to 6.
The opposite sides are supplementary
43+x=180
X=137
the correct answer is 83.
