Answer:
y=20,x=9
When doing problems like this it is important to always note: whatever you do to one side of the = sign you have to do to the other side.
Step-by-step explanation:
For this problem it helps that they already give you what y equals to so you can plug y in the top equation to figure out what x is. See attachment for step by step process
Answer:
c) v.v
Step-by-step explanation:
The Dot product also known as scalar product or inner product is the multiplication of two equal length vectors which results in a scalar.
Mathematically,
where and
are the magnitudes of the vectors a and b
is the angle between vectors a and b
If a and b are in the same direction then
if a and b are orthogonal (90°) then
To represent the square of the magnitude of a vector v
Hence option c is the correct answer
a. v/|v|
Here vector v is divided by its own magnitude
b. v.|v|
Here vector v is multiplied by its own magnitude
c. v.v
Represents the square of the magnitude of vector v
d. v^2.v^2
Represents the dot product of square of vector v
