Which are all the solutions of 5sinθ-4=2sinθ-4, where 0≤θ≤2π

Asystem of equations has 1 solution. if 4x-y=5 is one of the equations , which could be the other equation ?

I’m still confused on how to work the percentages

Atype of plant is introduced into an ecosystem and quickly begins to take over. a scientist counts the number of plants after mmonths and develops the equation p(m)= 19.3(1.089)^m to model the situation. most recently, the scientist counted 138 plants. assuming there are no limiting factors to the growth of the plants, about how many months have passed since the plants werefirst introduced? a)o 6.1b)0.6.6c)10 72d)o 23.1
