Answer:
R = 14 cm
A = pi R^2 = 3.14 " 196 = 616 cm^2
Answer:
6+(2x+4)=1/2-(3+x) okay I hope this is it.
Good luck on this.
Answer:
1)Rate of change, intersect, one, graph, intersect (i'm not really sure but this is what i think the answers are for 1)
Step-by-step explanation:
Answer:
-4sinθcosθ
Step-by-step explanation:
Note:
1. (a + b)^2 = a^2 + 2ab + b^2
2. (a - b)^2 = a^2 - 2ab + b^2
3. sin^2θ + cos^2θ = 1
(sinθ -cosθ)^2 - (sinθ + cosθ)^2
= sin^2θ - 2sinθcosθ + cos^2θ - (sin^2θ + 2sinθcosθ + cos^2θ)
= sin^2θ + cos^2θ - 2sinθcosθ - (sin^2θ + cos^2θ + 2sinθcosθ)
= 1 - 2sinθcosθ - (1 + 2sinθcosθ)
= 1- 2sinθcosθ -1 - 2sinθcosθ
= - 2sinθcosθ - 2sinθcosθ
= -4sinθcosθ
Instead of typing it all on here, I included my explanations with the work.
