ankoles [38]

Answer:

802+6 tenths.

Step-by-step explanation:

802 is not apart of the decimal. (I might sound stupid but I dont remember expanded form as much.) Only the 6 is apart of the decimal itself. 802 is just numbers. The 6 is pretty much the decimal.

What is the vector sum of (7,5) and (13,-5)
kolezko [41]

The vector sum of  two vectors as (7,5) and (13,-5) is given by v_1+v_2=20i+0j which can be written in point form as  (20,0) .

<u>Step-by-step explanation:</u>

Here we have , two vectors as (7,5) and (13,-5) Which are represented as :

v_1=7i+5j\\v_2=13i-5j

Addition of vector is as same as normal addition of integers as :

⇒ v_1+v_2=7i+5j+(13i-5j)

⇒ v_1+v_2=(7+13)i+(5-5)j

⇒ v_1+v_2=20i+0j ,

where i & j are the unit vectors in direction x-axis and y-axis respectively.

The vector sum of  two vectors as (7,5) and (13,-5) is given by v_1+v_2=20i+0j which can be written in point form as  (20,0) .
