Suppose f⃗ (x, y)=⟨ex, ey⟩f→(x, y)=⟨ex, ey⟩ and cc is the portion of the ellipse centered at the origin from the point (0,1)(0,1) to the point (7,0)(7,0) centered at the origin oriented clockwise. (a) find a vector parametric equation r⃗ (t)r→(t) for the portion of the ellipse described above for 0≤t≤π/20≤t≤π/2.

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.

Acircle has a radius of 12.6cm what is the exact length of an arc formed by a central angle measuring 120
