Answer: B and C
Step-by-step explanation:
U is positive and S is negative so it fits
U is the oppotite which would = -U and the opposite of that is U so that fits
Since
for
, we have
, so we take the positive root. Now,
- - -
In the first quadrant, cosine is positive, so
and in turn,
- - -
In the previous problem, we had
, so we must have
, which means
Answer:
I believe it is
1) yes
2) no
3) no
4)no
Step-by-step explanation:
It can only be a solution if you put the x in from the table into the x of the equation and the y in from the same ordered pair into the equation for y and if you get 1 for the fist equation it is a solution but you also have to get 7 for the second equation for it to fully be a solution. Also, you can go to desmos and enter the equations and then substitute the x's and y's... you will have to delete the =1 and =7 in order for the website to tell you what it equals.
Make a line plot and you got the answer
