PLEASE ANSWER ASAP (exponential and logarithms)

1.4650  (the first option in the list of possible answers)

Step-by-step explanation:

Start by isolating the exponential expression on one side of the equal sign, thus subtracting 2 from both sides:

Now, in order to solve for "x", we need to lower the exponent, and for that purpose we use logarithm base "3":

In order to find this logarithm, we use the change of base formula:

which rounded to four decimals gives: 1.4650

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
