The answer is D.
1 sq ft = 1 ft x 1 ft
= 12 in x 12 in
1 sq ft = 144 sq in
5 sq ft = 144 * 5 = 720 sq in.
I think that x^2-9 (difference of 2 squares), 216x^3 +729 (sum of 2 cubes), and the other two are none
Not entirely sure
Answer:
Step-by-step explanation:
Finding an equation of a tangent line to that function requires that we find the derivative of the function at that point. Since this is an absolute value function with its cusp at (2, 5), the function is not differentiable here.
