<em>d</em><em> </em><em>.</em><em> </em><em>49</em>
Step-by-step explanation:
<em>180-131</em><em> </em><em>(</em><em> </em><em>supplementary</em><em> </em><em>angle</em><em>)</em>
<em>=</em><em> </em><em>49</em><em>°</em>
Answer:
yes the answer is B
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
The average profit of the local store is an illustration of an exponential function
The profit function is: 
<h3>How to determine the function</h3>
From the question, we have:
- Initial value (a) = 960
- Rate per year (b) = 88%
An exponential function is represented as:

So, the function that represents the profit per year is:

Divide x by 12 to get the monthly rate

Evaluate the exponent

Hence, the profit function is:
