Step-by-step explanation:
<u>Original figure:</u> PQRTS
<u>Dilated figure:</u> P'Q'R'S'T'
<u>Take one of the corresponding sides of the figure and find the scale factor:</u>
- SR = 2, S'R' = 4
- Scale factor is 4/2 = 2
<u>The dilation rule as per above is:</u>
Correct option is A
To test if linear model, we fit the data into a line and solve for the correlation coefficient:
The equation is
y = -1537.5x + 5466.67
and the correlation coefficient is
R² = 0.964
The model can't be exponential growth since the daily supply decreases with time. So, the data is tested if it's exponential decay. The same procedure is done the exponential equation would be linearized in the form:
y = -2816.06 lnx + 4073.57
with correlation coefficient of
R² = 0.998
Since the correlation coefficient for the exponential decay model is closer to 1, it must be the right model.
