Which of the following is not a valid strategy for solving the given equation?
a. to solved the equation cos²θ= sinθcosθ, first subtract sinθcosθ from both sides, then factor out the common factor of cosθ on the left side. b. to solve the equation cos²θ=sinθcosθ, ***first divide both sides by cosθ.c. to solve sin2θ+2cosθsin2θ=0, first factor out the common factor of sin2θ on the left side. d. to solve the equation sinθ+cosθ=1, first square both sides of the equation.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?
