The expression 1.5 x 1.09^t models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his college.
Now In general we have the following rule for exponential functions:
Here we have two cases for b:
Case 1: if b<1 , we call it as exponential decay.
Case 2: if b>1 , we call it as exponential growth.
Now let us compare our equation with this general form,
1.5 x 1.09^t
Here b is 1.09, which is greater than 1.
So here we can say that the housing cost is increasing exponentially by a factor or 1.09.
Y/(X•grams), find the total cost of the gold, then use y to divide the whole thing.
I believe the y intercept is 4500 ft, since t=0, and the slope of the line would be 1500/( distance from t=0 to the x coordinate for 6000), the person is probably acending since it went from 4500 to 6000. Idk C D cause I don't have the graph
