A word to the wise: It's <span> f(x)=125(0.9)^x, where ^ represents exponentiation.
In this case the ave. value over the interval [11, 15] is
125(0.9)^15 - 125(0.9)^11
------------------------------------- = (125/4) [ 0.9^15 - 0.9^11)
15 - 11 = (31.25) [ 0.2059 - 0.3138 ] = a negative result
= (31.25)(-0.1079) = -3.372 (av. r. of c.
over the interval [11,15] )
Do the same thing for the time interval [1,5]. Then compare the two rates of change.</span>
The given area of the 
ft. by 33 ft. wall less the areas of the Windows and the Door give the area of the painted part of the wall as 
ft.²
<h3>How can the area of the painted part be calculated?</h3>
The area of the painted part of the wall is ft.²
The given dimensions of the wall are;
The width of the wall = ft.
The height of the wall = 33 ft.
The painted area = Area of the wall - (Area of the widows + The door)
Which gives;
The area of the painted part of the wall is ft.²

Answer:
Heyo. The answer is 60.48
Step-by-step explanation:
This is pretty easy, all you have to do is multiply the length, height, and width. Remember this. LxHxW. Thats is the formula. You do 4.2 cm, multiplied by 3.2 cm, then multiply that by 4.5 cm. Hope this helps! :)
Answer:
x=0 y=0
Step-by-step explanation:
