Answer: it's a '40.0-kg object, not a 40.4-kg object, which would explain why the answer is different.
Step-by-step explanation:
Answer:
a) x=
10°
50°
130°
10°
50°
130°
170°
250°
290°
b) x=
90°
210°
330°
Step-by-step explanation:
2 sin (3x) = 1
a) look at the graph, y=1 when x is near:
10°, 50°, 130°, etc
in the equation: 2 sin (3x) = 1 ⇒ sin (3x) = 0.5 ⇒ 3x = 30° (and others) ⇒ x = 10° (and others). So the values given in solution (10°, 50°, 130°, etc) are true
b) is evident
Answer:Answer: y=x/3−2.
Step-by-step explanation:
find the equation of the line perpendicular to the line y=2−3x passing through the point (3,−1).
The equation of the line in the slope-intercept form is y=2−3x.
The slope of the perpendicular line is negative inverse: m=13.
So, the equation of the perpendicular line is y=x3+a.
To find a, we use the fact that the line should pass through the given point: −1=(13)⋅(3)+a.
Thus, a=−2.
Therefore, the equation of the line is y=x3−2.
Answer: y=x/3−2.
