We can subtract the function that represents the cost in 2000 from the function that represents the cost in 1990.

Doing this gives us (-20t^{2}+1000)-(-10t^{2}+1500)=\boxed{-10t^{2}-500}

natulia [17]

The room is 5 inches long in the drawing.

Step-by-step explanation:

Given,

Scale drawing used by Kenneth;

1 inch = 4 feet

Ratio of scale = 1:4

Actual length of room = 20 feet

Let,

x be the length in drawing

Ratio of actual length = x:20

Using proportion

Scale ratio :: Actual ratio

1:4::x:20

Product of mean = Product of extreme

4*x=20*1\\4x=20

Dividing both sides by 4

\frac{4x}{4}=\frac{20}{4}\\x=5

The room is 5 inches long in the drawing.

Keywords: ratio, proportion
