Answer:
The form for an exponential equation is f(t)=P0(1+r)t/h where P0 is the initial value, t is the time variable, r is the rate and h is the number needed to ensure the units of t match up with the rate. Plug in the initial value for P and the rate for r. You will have f(t)=1,000(1.03)t/h. Find h.

Answer: although the question is incomplete, but from the details i got online, am able to give this answer.
A linear model is suitable. The regression relationship is thus ˆ
y= 0.511 + 0.159x where y = ridership and x = tourist numbers. Expected ridership if 10 million tourists visit is 2,101,000.The predicted ridership if there are no tourist at all is 511,000 though this prediction is out of sample and must be treated with caution as zero tourists is out of the data range used to form the model. The correlation coefficient is given by r=n∑XY-∑X∑Y/√[n∑X^2-(∑X)^2] [n∑Y^2-(∑Y)^2]
which equals 0.917 in this case. The R^2 = r^2 = 0.84.
Okay, for the first part, you just add it all together. So 7x+19x+9+18. For the second part, just combine like terms. So you would get 26x+27.
