a) The instantaneous rate of change is:
b) The slope of the tangent line is equal to the instantaneous rate of change found previously.
Answer: B
Step-by-step explanation:
Division of components are consistent - the same
Right triangle = Pythagoras theorem.
a^2+b^2=c^2
there's already c and b so
10^2-8^2=a^2
100-64= 36
a^2=36
square root both sides
to get 6.
Factories both equations:
5(x - 4) / (x + 2)(x - 4)
Then take out the common brackets:
5 / x + 2
Minus 2 from both sides:
3 / x
If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)
