Average rate of change: r=[f(b)-f(a)]/(b-a)
r=-60→[f(b)-f(a)]/(b-a)=-60
b=5; f(b)=-213; a=1; f(a)=27
(-213-27)/(5-1)=(-240)/4=-60
Answer: The <span>two points in the table which create an interval with an average rate of change of -60 are:
x f(x)
1 27
5 -213</span>

Answer:
46 mph
Step-by-step explanation:
Distance = speed x time
92 mi = speed x 2 hr
speed = 92/2 = 46 mph
Total surface area equals area of 5 rectangular faces + 2 pentagonal faces
Area of 5 rectangular faces
Area of 2 pentagonal faces can be found by drawing 5 isosceles triangles with height as shown in the diagram and multiply the result by 2.
The toatal surface area is
The correct answer is A
