A mass of 1 slug is attached to a spring whose constant is 5 lb/ft. Initially, the mass is released 1 foot below the equilibrium

position with a downward velocity of 3 ft/s, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 2 times the instantaneous velocity.
(a) Find the equation of motion if the mass is driven by an external force equal to f(t) = 8 cos 2t + 2 sin 2t.

If a = 5^x, b = 5^y and a^y×b^x = 25 then prove that: xy =1​
avanturin [10]

a =  {5}^{x}  \\ b =  {5}^{y}  \\  {a}^{y}  \times  {b}^{y}  = 25 \\ prove \: ( {5}^{x} )^{y}  \times ( {5}^{y} ) ^{x}  = 25 \\  {5}^{xy}  \times  {5}^{yx}  = {5}^{2} \\  {5 }^{xy + yx}  = 5^{2}  \\ 5^{2xy}  =  {5}^{2} \\ is \:  \: 2xy = 2 \\ xy =  \frac{2}{2}  \\ xy = 1

Which complex number is a distance of sqrt17 from the origin on the complex plane?
lions [1.4K]

Let z=x+iy be a complex number. The distance from this complex number to the origin is

\sqrt{(x-0)^2+(y-0)^2}=\sqrt{x^2+y^2}.

Consider all options:

A. z=2+15i, then \sqrt{2^2+15^2}=\sqrt{229}.

B. z=17+i, then \sqrt{17^2+1^2}=\sqrt{290}.

C. z=20-3i, then \sqrt{20^2+(-3)^2}=\sqrt{409}.

D. z=4-i, then \sqrt{4^2+(-1)^2}=\sqrt{17}.

Answer: correct choice is D.
