<span>average rate of change = (f(7) - f(5)) / (x7 - x5)
</span>f(7) = <span>12 (7^3) + 12 = 4128
f(5) = </span>12 (5^3) + 12 = 1512
so
average rate of change = (4128 - 1512)/(7-5)
average rate of change = 2616 / 2
average rate of change = 1308

If you times 39.99 by 0.20 (20%) then you get your answer of $7.99
Answer:
Step-by-step explanation:
As the two pools, Family pool and Dog pool, are similar, their interior angles are equal and their corresponding sides are in the same proportion:
LMNO ~ PQRS
so LM/PQ = MN/QR = NO/RS = OL/SP
substituting in the given values
4/2 = 6/c = a/5 = 7/b
c = 6/2 = 3
a = 5*2 = 10
b = 7/2 = 3.5Answer:
