Step-by-step explanation:
remember, tan = sin/cos.
of course, one solution is x = 0. sin(0) = 0, tan(0)=0).
for the general solution we look at x <> 0.
3×sin(x) = 2×tan(x) = 2×sin(x)/cos(x)
3 = 2/cos(x)
3×cos(x) = 2
cos(x) = 2/3
x = 48.1896851...°
d1 = ax + by + c = 0 and d2= mx + ky + f = 0
if they are parallel :
8x + 2y = 7
8x + 2y - 7 = 0
- 8x + 2y -9 = 0
- 4x + y -6 = 0
- 16x + 4y - 19 = 0
you can create more whatever you want =)
Hope this helps ^-^
Answer:
N= -4
Step-by-step explanation:
Step-by-step explanation:
just think it through :
0.4x + 20 < 200
0.4x < 180
x < 180/0.4 = 450
so, x < 450
they must order less than 450 bars.
therefore, the first answer option is correct :
they can order from 0 to 449 bars, but no more.
