Answer:
2nd option
Step-by-step explanation:
trinomial is 2x² + 10x -4 = 0
a = 2
b = 10
c = -4
(-b±√b²-4ac) / 2a
= [-10±√100-4(2)(-4)] / 2
= (-10±2
) / 4
= (-5+
)/2, = (-5-
)/2 (simplified)
Cos(42)=x/17000
X=17000*cos(42)
X=17000*0.743
X==12,631
I’m pretty sure Dani will pay $13.23 :) I hope I helped
