Please show all steps, I'm practicing for an exam. Thanks!! The path of a fighter jet is described by r (t) = (10−3t^2) i − (5/t^2) j + te^(3−3t) k , where distances are measured in kilometers (km) and t in minutes (min). A laser is fired in the tangential direction toward a target on the x-axis at the time t0 = 1. (a) What point on the x-axis does the laser hit? (b) Suppose the laser travels twice the...
Please solve QUESTION NO.1 in a clear and
comprehensive manner, explaining and showing all steps in detail.
The solution should be neat, organized and easy to understand. I'm writing an
Applied Maths exam in 3 hours.
Please do ALL parts. Please explain all STEPS including the
factorization theorem step. I am trying to understand this
material. Please Please be NEAT.

2. Consider the following system of ordinary differential equations, 3 y1 (t) 4у (t) dy1 (t)/dt dy2 (t)/dt 4y2(t), 3 y2(t) with initial conditions yı(0) = 1, y2(0) = 0. (a) Write down the system of ordinary differential equations in matrix-vector form. You should also give the initial conditions in vector form. [2] [6] (b) Find exp(At), where A is the matrix you found in (a)....
Please explain and show all the steps instead of just giving an
answer.
(Production function) Condsider a representitive firm with a production function which is (i) twice continuously differentiable; (i) exhibits positive and diminishing marginal product and (iii) has constant return to scale: 1. Y = F(K, L) Given the capital rental price R and the wage w, and the good price P is normalized to 1, the firm can choose K and L to maximize its profit: max F(K,...
Please answer all three parts.
(i) Take the laplace transform with respect to t
(ii) Solve the resultant integral in x

Q2 (6 points) If C is a smooth plane curve with parametrization r r(t),t E [a, b], then the curvature K(t) of C at the point r(t) is defined to be the magnitude of the rate of change -ll dT of the unit tangent vector with respect to the arc length. That is, = ds () [2p] Show that K(t) = ||F (C) xr" (t)|| r...
Please neatly show me how to solve these with all the correct
steps and explain so I can understand the process. Thanks
Part (a) Suppose the force exerted by a spring is F(x) = -kx and
the spring has constant k = 325 N/m. Then suppose a wooden cube
with mass m = 6 kg traveling with an initial velocity on a level
surface with kinetic coefficient of friction 0.250 presses against
the spring and it compresses from x =...
May you please explain all steps? I want to
understand this and am so confused.
Thanks!
