Answer:
C has a magnitud of 10.4 units and is directed 270° from the positive x-axis
Step-by-step explanation:
As it shows on the attached picture, the xA and xB have equal magnitudes but opposite directions, therefore they cancel eachother out in the x-axis.
However, the yA and yB are equal in magnitud, but have the same direction. So, the create a total vector the is completely on the y-axis and it's magnitude is 2*(sin(60°)*6)=10.4 units.
In order for C to cancel this vector, it's magnitude also needs to be 10.4 units, but pointing the other way. Therefore, the angle needs to be 270° from the positive x-axis.
To find x intercept ,
let f(x) = y
therefore y= 8x - 4
in solving for x intercept, me plug in y = 0
thus
8x - 4 =0
solving for x
8x = 4
dividing through by 8
8x/8 =4/8
x =4/8
x =1/2
therefore, the x intercept is 1/2
They must make up their mind. Either they should never, or else they should always.
B because you need to do 2/6 which is the probability of getting a number above 4 times 1/2 the probability of getting heads. 2/6 x 1/2 = 2/12 = 1/2
