Answer:
Choice C.
Step-by-step explanation:
3rd degree means that the expression must have power of 3 as the highest power.
So, choice b is wrong since it has highest power of 8. All the other choices have highest power of 3.
Binomial means expression that has two terms.
So, choices d and a are wrong because they have 3 terms each.
So, choice C is correct answer and also it has constant as 8.

Answer:
On the best-fit line for the points {(2,3) (5,7) (1,2) (4,8)}, one point is (0.5,1.25) and another is the y-intercept (0,0.5). Use the formula for the slope of a line, m = (y2 - y1)/(x2 - x1), to find the slope

Answer:
22.8 m/s at 17.4°
Step-by-step explanation:
You want to find the resultant of ...
3 cis 0° +20 cis 20° = (3, 0) +(18.794, 6.840) = (21.794, 6.840)
The magnitude is the root of the sum of the squares of the velocities in the horizontal and vertical directions:
s = √(21.794² +6.840²) ≈ 22.8
The direction is found from the fact that the tangent of the angle is the ratio of vertical to horizontal coordinates:
angle = arctan(6.840/21.794) ≈ 17.4°
The resultant velocity is 22.8∠17.4° meters per second.
