The length of side c would be 8.
Step-by-step explanation:
Given that,
a = 4
b = 6
cosC = -1/4
If we are given two sides and angle, the law of Cosines can be used to find the third side:
By inserting the values in the formula, we get
c = 8.
Therefore, the length of side c would be 8.
(2*length)+(2*width)=perimeter
length=4+2w
(2(4+2w))+(2(w))=74
74=(8+4w)+(2w)
74=6w+8
66=6w
w=11
length=4+2(11)
l=4+22
l=26
Ok. Because there are 6 people and 8 pieces. So 6 people have 1 slice each. The other 2 pieces.
The other 2 pieces have to divide both pieces into 3 hat way everyone has a pieces
Every one will have 1 1/3 pieces.
Remember,
, where
is circumference and tex]d[/tex] is the diameter. They are related by a constant
(pi).
We can solve the above equation for d and then substitute our known values.
I think the correct answer from the choices listed above is option A. A limitation of the kinetic-molecular theory for a gas is the <span>theory assumes that particles do not experience intermolecular forces.This cannot be completely true since interactions between particles is normal.</span>
