40 * 50= 2,000

Easy way to find this out!

4*5=20.

You take the 0 from 40 and the 0 from 50 and you have 

20 +0 zeros.

2000 which is 2,000!

Answer:

3,750 cars.

Step-by-step explanation:

We are given that the equation:

y=9000-2.4x

Models the relationsip between <em>y</em>, the number of unfilled seats in the stadium, and <em>x</em>, the number of cars in the parking lot.

We want to determine the number of cars in the parking lot when there are no unfilled seats in the stadium.

When there are no unfilled seats in the stadium, <em>y</em> = 0. Thus:

0=9000-2.4x

Solve for <em>x</em>. Subtract 9000 from both sides:

-2.4x=-9000

Divide both sides by -2.4:

x=3750

So, there will be 3,750 cars in the parking lot when there are no unfilled seats in the stadium.

Answer:

Situation 1 is exponential decay. Situation 2 is linear. Situation 3 is exponential growth.

Step-by-step explanation:

Situation 1 is exponential decay because it declined in a non linear way.

600-480=120 480-364=116

Situation 2 is linear because when it declined it has a dependent to another.

400-340=60 340-280=60

Situation 3 is exponential growth because is increases.
