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

The answer to the question is -1,-1
Answer:
$6.87
Step-by-step explanation:
For the blueberries we multiply 3.98 with .6 pounds to get 2.39
We do the same for the other item 2.49 X 1.8 = 4.48
Total the two for the answer:
2.39 + 4.48 = 6.87
35.937 inches cubed
