## AMDM

4th 6 weeks Review

### Functions

• You plan on working out over spring break and your workout consists of walking to the gym which burns 200 calories and then riding a stationary bike. Each minute on the bike burns 50 calories.

• Make a table modeling this story.

### Functions

LINEAR!!!! Snap.

Notice that the differences are the same!!!

What does this tell us????

### Functions

The same difference is also called a constant rate of change.

This terminology is AKA ?

Slope

Y=mx+b

Y=50x+ 200

This is the explicit

linear function for this

Problem.

### functions

• y=50x+200

• How many calories will be burned in 35 minutes?

• How long will it take to burn 1500 calories?

### functions

• y=50x+200

• The above is the explicit function.

• What does the recursive rule look like?

Where,

### functions

• Bouncing ball. 60% rebound rate.

• Make a table for each bounce if dropped from an initial height of 15 ft.

Notice the differences

Are not the same so it

Cannot be linear!!!

### Functions

• Ratios are the same at .6 which should make sense because the rebound rate was 60%.

• So write the explicit function. (These have the y and x in them)

A is the initial amount. B is the ratio.

### functions

• What would be the height of the 6th bounce if dropped from an initial height of 36 meters?

### Functions

• The recursive rule look like this:

Where P0=15

### Functions

• You deposit \$3500 into a savings account.

• The account pays 6.2% each year.

• If you do not make another contribution to the account. How much will the account be in 15 years?

• 20 years?

• What if you deposit another 500 each year?

• How will the table change?

### Functions

• Ferris Wheel Questions.

• Steps.

• Draw the circle. Label the dimensions.

• Find the circumference.

• How long does it take to make a complete revolution.

• Take your time and sketch each triangle.

### Beijing Great Wheel

198 m diameter.

Total height of 208 m.

15.55 meters per minutes.

Find height at 8/19/35 minutes.

What is the sinusoidal equation?

What is the period?

What is the amplitude?
