The historical prices of a car with the same make, model, and fea- tures are recorded for a period of 10 years as shown in the table.

a. Construct a scatterplot for the data.
b. Determine the exponential depreciation formula that models this
data. Round all numbers to the nearest hundredth.
c. Determine the depreciation rate to the nearest percent.
d. Use the model equation to predict the value of this car after
66 months. Round to the nearest

step-by-step explanation:

1. practice, practice & more practice

2. review errors

3. master the key concepts

do not try to memorise the processes.

4. understand your doubts.

5. create a distraction free study environment

6. create a mathematical dictionary

7. apply maths to real world problems.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
