The third option but can also be the first option, The would proportionate properly.
Answer:
7.9
Step-by-step explanation:
k^2 = 3.7^2+5.2^2-2(3.7)(5.2)\cos 124
k
2
=3.7
2
+5.2
2
−2(3.7)(5.2)cos124
Plug in values.
k^2 = 13.69+27.04-2(3.7)(5.2)(-0.559193)
k
2
=13.69+27.04−2(3.7)(5.2)(−0.559193)
Square and find cosine.
k^2 = 13.69+27.04+21.51774
k
2
=13.69+27.04+21.51774
Multiply.
k^2 = 62.24774
k
2
=62.24774
Add.
k=\sqrt{62.24774} \approx7.89 \approx7.9
k=
62.24774
≈7.89≈7.9
Answer:
- 5/3
Step-by-step explanation:
Line is passing through the points (0, 2) & (3, - 3)
Slope of the graph = (- 3 - 2)/(3 - 0) = - 5/3
53.9 is incorrect rounding. This is because the 4 in the 100’s place is below 5. The correct rounding would be 53.85
