Hey, There i hope you are haveing a great day :) So I look at the example so it should be the same I think like how you work out the mean by adding all the numbers and then diving them so, (8 + 4 + 8 + 8 + 10 + 2 + 4 + 4) = 48 and now you know you have got 8 numbers there a divide them so 48/8 = 6. and then I think you take away it so, 8 - 6 = 2 4 - 6 =-2 8 - 6 = 2 8 - 6 = 2 10 - 6 = 4 2 - 6 = -4 4 - 6 = -2 4 - 6 = -2 and then 2 + -2 + 2 + 2 + 4 + -4 + -2 + -2 divide 8 = 0 and you can't divide anything by 0 so that would be the answer.

is vector v with an initial point of (-5,22) and a terminal point of (20,60) equal to vector u with an intintal point of (50,120

marta [7]

Answer:

Yes, vectors u and v are equal.

Step-by-step explanation:

We need to check whether vectors u and v are equal or not.

If the initial point is $(x_1,y_1)$ and terminal point is $(x_2,y_2)$ , then the vector is

$Vector=(x_2-x_1)i+(y_2-y_1)j$

Vector v with an initial point of (-5,22) and a terminal point of (20,60).

$\overrightarrow v=(20-(-5))i+(60-22)j$

$\overrightarrow v=25i+38j$ ..... (1)

Vector u with an initial point of (50,120) and a terminal point of (75,158).

$\overrightarrow u=(75-50)i+(158-120)j$

$\overrightarrow u=25i+38j$ .... (2)

From (1) and (2) we get

$\overrightarrow u=\overrightarrow v$

Therefore, vectors u and v are equal.

You have $75.00 to spend at the mall. You want to buy a hoodie that costs $80.00. The store is having a 20%-off sale. (There is

$80.00 x 0.20 = $16.00
$80.00 - 16.00 = $64.00
the hoodie costed $64.00
you were left with $16 to spare
