I believe the answers are c and d
Its also 40°30' because the median is also a bisector in isosceles triangle
Answer & Step-by-step explanation:
When we see the phrase "rate of change" then it means that we are looking for the slope. So, we will need to know the formula for finding slope or the rate of change.

Now, let's use this equation to solve for the rate of change of each question.
<u>Problem 1:</u>

<em>The rate of change of this equation is 2/3</em>
<u>Problem 2:</u>
<u></u>
<u></u>
<em>The rate of change for this equation is 2</em>
<u>Problem 3:</u>
<u></u>
<u></u>
<em>The rate of change for this equation is 6</em>
