Answer: 
<u>Step-by-step explanation:</u>
Area (A): 
Length (L): 
width (w): W
A = L x W
=
x W

= 
x W


Yes she would. bc she run up 4.5 and since she is goin back down the same amount it would be negative and so she will end up at 0
A. -1 Because you would divide 3x and -6 by 2.
Answer:
(a) f'(1)=-4
(b) y+4x-4=0
Step-by-step explanation:
<u>Tangent Line of a Function</u>
Given f(x) a real differentiable function in x=a, the slope of the tangent line of the function in x=a is given by f'(x=a). Where f' is the first derivative of f.
We are given

The derivative is

(a) The slope of the tangent line at (1,0) is


(b) The equation of the tangent line can be found with the general formula of the line:

Where m is the slope and the point (xo,yo) belongs to the line. We have m=-4, xo=1, yo=0, thus

Or, equivalently

Marcy bought a total of 22.8 potatoes. 10.32+12.48=22.8
