Answer:
1500
Step-by-step explanation:
The average rate of change of a function on the interval [a, b] is given by ...
rate of change = (f(b) -f(a))/(b -a)
On the interval [7, 9], the average rate of change is ...
(5760 -1920)/(9 -7) = 3840/2 = 1920
On the interval [4, 6], the average rate of change is ...
(945 -105)/(6 -4) = 840/2 = 420
The rate of change on the first interval is greater by ...
1920 -420 = 1500

Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Answer:
433.5 in²
Step-by-step explanation:
A cube has 6 sides
Area of 1 side = 8.5 x 8.5 = 72.25 in²
Area of 6 sides = 72.25 x 6 = 433.5 in²
