2. A salmon swims in the direction of N 30° W at 6 mi/h relative to the ocean. The ocean current flows due east at 6 mi/h. (a) Express the velocity of the ocean as a vector. (b) Express the velocity of the salmon relative to the ocean as a vector. (c) Find the true velocity of the salmon as a vector. (d) Find the true speed of the salmon. (e) Find the true direction of the salmon. Express your answer as a heading.
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
