Over the past several months, the water level of a lake has been decreasing by 7% each week. If the highest water level before the decrease started was 540 ft., what was the level at the end of 8 weeks?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Which graph represents the function g(x) = |x + 4| + 2?
