The answer for this question is 20.0
Answer:
a) mt = -2
b) y=2-2x
Step-by-step explanation:
We have
⇒
and we must find
a) The slope of the tangent line to the curve at the point (1,0)
b) The equation of the tangent line in part (a)
a)
with the point (1,0) then f'(x)
the slope (mt) in x=1 is
f'(1)=
, m t= -2
b) mt=-2 at the point (1,0), knowing that the pending point model is:
, we solve y-0 = -2(x-1) ⇒ y=-2x+2
Convert 2 km into cm
1 km = 100,000 cm
2 km = 200,000 cm
therefore 9,000 cm is greater
