Answer:

  • 35.2

Step-by-step explanation:

<u>Find the missing angle:</u>

  • m∠L = 180° - 60° - 45° = 75°

<u>Use the law of sines to determine the lengths of the sides:</u>

  • LM / sin ∠K = KM / sin 75°
  • 12 / sin 60° = KM / sin 75
  • KM = 12 sin 75° /sin 60° = 13.4 (rounded)
  • KL / sin ∠M = LM / sin ∠K
  • KL / sin 45° = 12 / sin 60°
  • KL = 12 sin 45° / sin 60° = 9.8 (rounded)

<u>Find perimeter:</u>

  • P = 12 + 13.4 + 9.8 = 35.2

Find the general solution of the following equation: y'(t) = 3y -5
Anton [14]

Answer:

The general solution of the equation is y = \frac{A}{3}e^{3t} + 5

Step-by-step explanation:

Since the differential equation is given as y'(t) = 3y -5

The differential equation is re-written as

dy/dt = 3y - 5

separating the variables, we have

dy/(3y - 5) = dt

dy/(3y - 5) = dt

integrating both sides, we have

∫dy/(3y - 5) = ∫dt

∫3dy/[3(3y - 5)] = ∫dt

(1/3)∫3dy/(3y - 5) = ∫dt

(1/3)㏑(3y - 5) = t + C

㏑(3y - 5) = 3t + 3C

taking exponents of both sides, we have

exp[㏑(3y - 5)] = exp(3t + 3C)

3y - 5 = e^{3t}e^{3C}        

3y - 5 = Ae^{3t}                A = e^{3C}

3y = Ae^{3t} + 5    

dividing through by 3, we have

y = \frac{A}{3}e^{3t} + 5

So, the general solution of the equation is y = \frac{A}{3}e^{3t} + 5
