7 - 3 = 4....so there is a $ 4 profit for every unit sold
4x = 3600
x = 3600/4
x = 900....so 900 units have to be sold to earn a profit of $ 3600
Answer:
Part I : 100°
Part II : a = 29.2
Part III : b = 20.95
Step-by-step explanation:
See the attached diagram of the triangle.
Part I: ∠ A = 180° - ∠ B - ∠ C = 180° - 45° - 35° = 100°
Part II: Now, applying the law of sines, we have
⇒
⇒
⇒ a = 29.2 (Answer)
Part III: Now, applying law of cosine, we have
b = a cos 35° + c cos 100° = 29.2 cos 35° + 17 cos 100° = 20.95 (Answer)
In the fomr
ax+by=c
-a/b=slope
4x-8y=11
a=1
b=-8
slope=-4/-8=4/8=1/2
0.1351 maybe? I'm not sure
