Find a formula f⃗ =⟨ f1(x, y), f2(x, y) ⟩ for the vector field in the plane that has the properties that f⃗ (0,0)=⟨0,0⟩ and that at any other point (a, b)≠(0,0) the vector field f⃗ is tangent to the circle x2+y2=a2+b2 and points in the clockwise direction with magnitude ∥f⃗ (a, b)∥=2a2+b2√.

b

step-by-step explanation:

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
