Sales of SUVs​ (sport utility​ vehicles) in the United States ​(in millions) for the years​ 1990-1999 can be modeled by the quadratic equation shown below. y = 0.016x^2 + 0.124x + 0.787
Here x=0 represents​ 1990, x=1 represents​ 1991, and so on. Use the model to approximate sales in 1998.

Sales in 1998 were approximately __ million SUVs.

Answers

Answer 1
Answer: If x = 0 is 1990, x = 1 is 1991, then 1998 is represented by x = 8. Substitute this value of x into the quadratic equation to find y:
y = 0.016*(8^2) + 0.124*8 + 0.787 = 1.024 + 0.992 + 0.787 = 2.803
Therefore, there were approximately 2.803 million SUVs sold in 1998.

a new car that costs $22575 depreciates at a rate of 11% per year. The car's value can be modeled by the equation V(x)=22,575(0.89)x. evaluate the function over the domain (2,5,7) and interpet the results

Answers

Answer: The values of the function V(x) over the domain (2, 5, 7) are 17881.66, 12,606.01 and 9985.224.

Explanation:

The cost of car is $22575 and the value of car depreciate at a rate of 11% per year.

The value of car can be modeled by the equation,

Where is number of years after purchase of car or the age of car. We have to find the value of the function over the domain (2,5,7), so put x=2,

It means the value of car will be $17881.66 after two years.

put x=5,

It means the value of car will be $12,606.01 after five years.

put x=7,

It means the value of car will be $9985.224 after seven years.
