The volume of a gas "V" varies inversely with the pressure "P" put on it. If the volume is 360cm³ under a pressure of 20 kgcm2

Sav [38]

Answer:

15 Kg cm²

Step-by-step explanation:

Given that V varies inversely with P then the equation relating them is

V = $\frac{k}{P}$ ← k is the constant of variation

To find k use the condition

V = 360, P = 20, then

360 = $\frac{k}{20}$ ( multiply both sides by 20 )

k = 7200

V = $\frac{7200}{P}$ ← equation of variation

When V = 480, then

480 = $\frac{7200}{P}$ ( multiply both sides by P )

480P = 7200 ( divide both sides by 480 )

P = 15

If U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }. A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 } .Find

Zina [86]

Answer:

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = {2, 4}

Step-by-step explanation:

Given the set :

U = { 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 }

A={1 , 2 , 3 , 4 } , B= {2 , 4 , 6 , 8 }

(A - B) = elements of A which are not in B

(A - B) = {1, 3}

(A - B)' = the complement of A - B ; element in the universal set which are not in A - B

(A - B)' = {2, 4, 5, 6, 7, 8, 9}

(A n B) = elements in both set A and set B

(A n B) = {2, 4}
