1. Observe that the f(t) is change by 4 per time t => there's a acceleration of 4 => f''(t) = 4; Take the derivative of it we can get a velocity function. f'(t) = 4t + c. Since the velocity from 100 to 80 is -20 (average), this means at t = 0, f'(0) = -22 => f'(t) = 4t - 22; Take the derivative again to get the position function: f(t) = 2t^2 - 22t + d, here d = 100 should be trivial. So, the function that models the relationship is f(t) = 2t^2 - 22t + 100.
2. By the compound interest formula:
A = P (1 + r/n)^(nt) , since it's yearly, so n = 1;
results A(t) = 100 (1+0.12)^t.
3. The average rate of change is basically finding the slope, m = y1 - y2 / x1 - x2.

Answer: Hello your question lacks some details attached below is the complete question
answer:
- Place a compass at point Q ,
-
measure arc PQ
-
Draw an arc with the compass that is equal to PQ
,
- Place the compass at point R
,
- cut through the line to the left of R with the arc in compass,
-
Assume the new points to be P' and R be Q'
, where P' Q' will become the new image of PQ with their end point will be R
Step-by-step explanation:
The steps required to draw an arc intersecting the line that will create a segment with length PQ are ;
Place a compass at point Q , measure arc PQ
Draw an arc with the compass that is equal to PQ
, Place the compass at point R
, cut through the line to the left of R with the arc in compass,
Assume the new points to be P' and R be Q'
, where P' Q' will become the new image of PQ with their end point will be R
