In the year 2000, the average cost of a computer could be modeled by the equation c = -5t2 + 750, where t is the number of years since 2000. by the year 2008 the average cost had changed, so it could be modeled by the equation c = -10t2 + 500. find the difference in the average costs for a computer between 2008 and 2000.

Step-by-step explanation:

Given:

The average cost of a computer in the year 2000 is given as:

The average cost of a computer in the year 2008 is given as:

Now, the difference in average cost between the years 2008 and 2000 can be calculated by subtracting the average cost in 2000 from the average cost in 2008.

Framing in equation form, we get:

Difference in average cost (ΔC) is given as:

Therefore, the difference in the costs for a computer between 2008 and 2000 is

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
