A washing machine was purchased for $700 and loses 1/4 of its value each year. Enter the function f(t) that describes the value of the washing machine as a function of time in years, t.

Type: f(t)=a(1-r)^t

Use your equation from the previous question:

A washing machine was purchased for $700 and loses 1/4 of its value each year. How much is the washing machine worth after 4 years?

Write a function to represent the height of the helicopter.

Type: f(t)=-mt+b

m is the slope rise/run

b is the y-intercept

What is the width of the walkway? (solve for w)

Hint:

Length = 17+2w

Width = 13+2w

Area = 396

Area = (Length)(Width)

396 = (17+2w)(13+2w)

-FOIL the right side^

-Subtract 396

-Factor or use Quadratic Formula to solve for w.

x represents the number of passengers in addition to the driver.

Table 3 shows the number of drivers and accidents by age of driver in the USA each year.

Your classmate, Kelly, claims that 16-year-olds are actually the safest teenage drivers because they have the least number of accidents. Do you agree or disagree with Kelly? Explain any mathematics you did to reach your conclusion.

The table above shows data for new drivers in different states. Use the information to determine the average rate of change from states that require 20 hours of practice to states that require 100 hours.

Explain what the rate of change represents for this table (use your answer from above)

A recent study reported the probability of a driver committing a moving violation during each of the first 8 months after getting their license.

Put these drivers in order from LEAST likely to get a ticket to MOST likely

A new law would make it so that those 13,000 new drivers would need a permit for 12 months before they can get their license at 16 years old. How many accidents can we expect then?

Given all the data from above, and using your answers from this section....What changes would you recommend to the state to make the roads safer?

Recommendations could include:

-Changing the age a driver can get their permit

-The number of practice hours required

-The amount of time a driver must hold their permit

-The age a driver can get their license
