Each of the following linear system has complex eigenvalues. For eachsystem, (a) find the eigenvalues; (b) determine if the origin is a spiral sink, a spiral source, or a center; (c) determine the natural period and natural frequency of the oscillations; (d) determine the direction of the oscillations in the phase plane; and (e)using HPGSystemSolver, sketch thexy-phase portrait and thex(t)- andy(t)-graphsfor the solutions with the indicated initial conditions:

answer: ur v dumb

step-by-step explanation:

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
