<span>At 8in to 250 feet the skyscraper converts to the following.
1.6 in/8 in x 250ft = 50 ft long
2.8in/8in x 250ft = 87.5 ft wide
11.2in/8in x 250ft = 350 ft high
You get this because every 8 in is 250 feet so you need to calculate the ratio of scale to that 8in per 250 feet.</span>
Answer:
The average rate of change of the function
over the interval
is -1
Step-by-step explanation:
We are given the function
over the interval 
We need to find average rate of change.
The formula used to find average rate of change is : 
We have b=-1 and a=-11
Finding g(b) = g(-1)

Finding g(a) = g(-11)

Finding average rate of change

So, the average rate of change of the function
over the interval
is -1

Hence,

is cutting each other in this equation.
So,

can be of any value.i.e.,infinite.
Hope this will help you.

The answer is (15,0) because the format is (x,y) so (15,0) means that it is on the x axis only !
