Answer:

From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36

So,

x = 72

y = 36

The function that gives the shares received by a post whereby each friend

shares the post a constant multiple of times each day is exponential.

<h3>Responses;</h3>

Ben's social media post: <u>2 × 3ⁿ</u>

Carter's social media post: <u>10 × 2ⁿ</u>

<h3>Methods by which the above expressions are obtained:</h3><h3 /><h3>Ben's social media posts;</h3><h3 /><h3>Given:</h3>

The given table of values for Ben's social media post is presented as follows;

$\begin{tabular}{|c|c|}Day&Number of shares\\0&2\\1&6\\2&18\end{array}\right]$

<h3>Solution:</h3>

The number of shares triples everyday, therefore, the number of shares form a geometric progression, with a common ratio of r = 3, and a first term of <em>a</em> = 2

The function for the number of shares of Ben's post is, tₙ = a·rⁿ

Which gives;
