2 17 4 28 6 42 The points (2,17), (4,28), and (6,42) do not lie in a straight line, so the relations is not linear. Let's assume they form a quadratic of the form y = ax^2 + bx + c subbing in the values, I get 4a + 2b + c = 17 16a + 4b + c = 28 36a + 6b + c = 42 start by ...

Physics
(a) Kepler's Third law for objects orbiting the sun says: a^3 = P^2, where P is the period in years and a is the semimajor axis in a.u. . Since P = 72.0 y, a = 17.31 a.u. (b) 2a = (perihelion distance)+ (aphelion distance) Therefore aphelion (greatest) distance = 34.0 a.u. The...

let s be the speed of the dog s^2 = 25^2 + 1.75^2 - 2(25)(1.75)cos 145° s = 26.45m/s Let θ be the direction of travel sinθ/1.75 = sin145°/26.45 θ = 2.17° So, the dog's velocity is 26.45 m/s at N2.17°E

At t = 1.6 sec., the man has jogged 1.76m. From that point on, the dog closes in on the man at the speed of 3.8 - 1.1 = 2.7m/s. The time for the dog to catch the man is therefore t = 1.76/2.7 = .65s. The man will have jogged .717m further for a total distance of 2.477m. The ...
