Answer:

<em>f(50) = 109.44943 feet</em>

Step-by-step explanation:

<u>Modeling</u>

The model of a situation where the skid distance f is measured against the car speed x can be expressed as:

f(x) = 0.0425x^2 + 0.07381x - 0.49107

Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:

f(50) = 0.0425*50^2 + 0.07381*50 - 0.49107

f(50) = 106.25 + 3.6905 - 0.49107

f(50) = 109.44943 feet

The answer is: y=-4x+29

To solve this, you need to know the y-intercept. 
1. y=-4x+b
2. 9+-4(5)+b
3. 9=-20+b
4. b=9+20
5. b=29
6. Substitute into y=-4x+b

Answer:

Look at explanation.

Step-by-step explanation:

For the first four, take the first term and add the common difference to it to get the second term. Then add the common difference to the second term to get the third term, and so on until the 5th term. If the common difference is negative, you subtract it instead of adding it.
