Answer:
Answer is 2
Step-by-step explanation:
We know that average rate of change of a function f(x) in the interval (a,b) is

Using this we can say that

Using properties of integration we have
3 to 6 integral = 20-5 =15
0 to2 integral = -3=5 =-8
Thus integral form 0 to 6 would be = -8+15+5 = 12
Average rate of change form 0 to 6 = 
Answer is 2
B. is the answer I believe since most are not functions
The area of the track will be 78501 m². The area of the track is equal to the area of the circle.
<h3>What is the area?</h3>
The space filled by a flat form or the surface of an item is known as the area.
The number of unit squares that cover the surface of a closed-form is the figure's area. Square meters and other similar units are used to measure area.
The area of the track is found as;

Hence, the area of the track will be 78501 m².

For 121212 guests we need 555 liters,for 363636 guests how many liters
Guests Soda
121212 555
363636 x
So 121212*x=363636*555
x=363636*555/121212
x=555*3
x=1665
