A man shares his money to on his two sons

Ronch [10]

Answer:

$150 is the amount of share Kwame has, and he has 3 shares.

Step-by-step explanation:

Kofi and Kwame's shares have a ratio of 2:3.

Kofi's share (2) is 100 dollars.

First, divide 100 with 2, to find the amount each share is worth:

100/2 = 50

One share = $50.

Now, note that Kwame has 3 shares. Multiply 3 with 50

3 x 50 = $150

$150 is the amount of share Kwame has, and he has 3 shares.

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

snow_tiger [21]

$\nabla f=(xy\cos xy+\sin xy)\,\vec\imath+x^2\cos xy\,\vec\jmath$

then we should have

$\dfrac{\partial f}{\partial y}=x^2\cos xy\implies f(x,y)=x\sin xy+g(x)$

Differentiating with respect to $x$ gives

$\dfrac{\partial f}{\partial x}=xy\cos xy+\sin xy=\sin xy+xy\cos xy+g'(x)$

$\implies g'(x)=0\implies g(x)=C$

So $F$ is indeed conservative, and

$f(x,y)=x\sin xy+C$

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}
