We can model the function between a and b as a linear function of negative slope because it is a short interval and the change is not very significant.
We have then that the average rate of change in that interval is:
m = (f (a) - f (b)) / (a-b)
Substituting the values:
m = (34.25 - 26) / (2.5-3.6)
m = -7.5
Negative, because the function decreases in that interval.
Answer:
a reasonable estimate of the average rate of change of the height of the rocket, in meters per second, between a and b seconds is:
m = -7.5 m / s
The best unit for measuring the length of an eyelash is millimeters
Y=4x-3
M of new line = -1/4
y=(-1/4)x+b
3=(-1/4)(-3)+b
3=(3/4)+b
b=9/4
y=(-1/4)x+(9/4)
The coefficient is 9 because it is not talking about the variable or power.
