Answer:
-3.75 but i would guess -3
Step-by-step explanation:
A = (-10 - 5) / (4 - 0) = -15 / 4 = -3.75
average rate of change of function f(x) between x = a and x = b
Here, a = 0; f(a) = f(0) = -5; b = 4; f(b) = f(4) = -10
the training started at 7:15 a.m
k=13t-2
=13*3-2
=39-2
37
74
74+73+71+73+73+74=438÷6=73
