<u>Answer:</u>
Option C. The solution for the system of equations is (-1,7) and (-4,13)
<u>Solution:
</u>
The equation for the system given is,
Now we can write,
(//simplifying)
When
When
So, solution is C, (-4,13) and (-1,7)
Work is force times distance. Note that the only work done here is in the direction opposed to gravity, or if you prefer the change in height times the weight...
W=3sin20(8*9.8)
W≈80.44 J
Answer:
D 1/16
Step-by-step explanation:
(1/2)^4=.0625
.0625= 1/16
Answer:
See below.
Step-by-step explanation:
Positive association is when the line has a positive slope, and the line progresses upwards.
E.g. When a car is traveling, as time progresses, the distance traveled increases.
Negative association is when the line has a negative slope, and the line declines.
E.g. When a car is traveling, as time progresses, the amount of gasoline decreases.
No association is when there is no slope between points, nor is there a line.
