Answer:
2/25
Step-by-step explanation:^2 = 1/25
Cubic Root 8 = cubic root = 2^3 = 2
(1/25)*(2) = 2/25

Answer:
the length— 6 
width— is 9 
Step-by-step explanation:
you said One side— 3m MORE 
so we will consider the length Number as X 
we will consider width As three plus X 
- You want to know the Perimeter. So we have to 
add. 
— so the expression is 3+3+x+x+x+x = 30 
it is then simplified to 6+4x= 30 
then we should be able to find out the X  which is 6
when we substitute the values with dimensions, you will get 
your final Answer

Answer:

Step-by-step explanation:
Given information: |a| = 80, |b| = 50, the angle between a and b is 3π/4.
We need to find the dot product  a · b.
The formula of dot product is

where, θ is the angle between a and b.
Substitute the given values in the above formula.


 
           ![[\because \cos (\pi-\theta)=-\cos \theta]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Ccos%20%28%5Cpi-%5Ctheta%29%3D-%5Ccos%20%5Ctheta%5D)


Rationalize the above equation.



Therefore, the value of a · b is  .
