Trigonometry: Simplify. tan x sin 2x

1 answer:

8 0

[2 sin(x) cos(x)] X [Sin(x)/cos(x)]

The cosines cancel out, as one is in the numerator and one is in the denominator. So you are left with:: 

2 sin(x) sin(x) 

or: 

2 sin(x) [squared]

I hope this helps!

Genrish500 [490]

Answer:

10 students/van

48 students/bus

Step-by-step explanation:

(a) 13v+5b = 370

(b) 12v+10b = 600

(a) - (b)

v -5b = -230

v = 5b-230

12(5b-230) + 10b = 600

60b+10b -2760=600

70b=3360

7b=336

b=48

v = 5(48) - 230 = 10

v = 10

Let's check

12(10) +10(48) = 600
