Given:
Two vectors are:
To find:
The projection of u onto v.
Solution:
Magnitude of a vector 
is:
Dot product of two vector 
and 
is:
Formula for projection of u onto v is:
On further simplification, we get
Therefore, the projection of u onto v is .
Answer:
x=4.0625 cm
Step-by-step explanation:
The Pythagorean theorem states that the square of the hypotenuse of a right triangle equals the sum of the squares of the two legs.
Not knowing which is the hypotenuse, lets assume that (x+5)cm is the hypotenuse:
(x+5)^2= 9^2+(x-3)^2
(x^2+10x+25)=81+(x^2-6x+9)
x^2+10x+25=81+x^2-6x+9
16x=65
x=4.0625
Checking:
(4.0625+5)^2=9^2+(4.0625-3)^2
82.1289=82.1289
Answer:
p-6=-14
Step-by-step explanation:
since it is said that it is the difference between them
If it was added to water then the answer will be the first one (it would dissolve)
Sorry, didn't see this til now.
-(u-4x-4)=-u+4x+4
