<span><span>The average rate of change formula is basically the slope formula, where you plug in: f(b)-f(a)/b-a. Then plug in the numbers. [f(0)=1,f(3)=7)]. So, 7-1/3-0. 6/3 is 2 so the average rate of change is 2. And that makes sense because the average rate of change is always the slope, and the slope is 2.</span></span>
Answer:
216 cm²
Step-by-step explanation:
The shape has six faces of the 11 cm height triangles and 6 faces of the 7 cm height triangles.
The base for all of the triangles is 4
4(11)/2=22
4(7)/2=14
6(22+14)=216
The 41th term would be 96.
You were doing it right. Here is a picture of my work.
