Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 10, 10 ], thus
f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208
f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus
average rate of change =
=
= 9
Answer:
3 3/8
Step-by-step explanation:
6 minus 2 5/8 equals 3 3/8
3 3/8 plus 2 5/8 equals 6
(centimeter/minute): 17
(miles per hour): 0.00633799
Answer:
b,f
Step-by-step explanation:
b: if sandi scored 3 more points than randi, then sandis points are equal to 3+randi
f: so the equation is 3+r=s,
so input values
3+r=18
r=18-3
r=15
