Answer:
TAN(x°) = 420/2000 --> x = 11.86° ≈ 12°
That would be 16 because all the others are multiples of 3.
Answer:c
Step-by-step explanation:
lower price = 3
higher price =11
p(x) = -2(x-3) (x-11)
Setting equal to zero
0 = -2(x-3) (x-11)
Using the zero product property
x-3 = 0 x-11 =0
x=3 x = 11
0.714 mins
by using the rule of three:
180 mins----->252 ballons
x----------------1 ballon=0.714 mins
x = 59
3x - 33 = 2x + 26
-2x -2x
1x - 33 = 26
+33 +33
1x = 59
