Expand (4x-3y)^4 using pascal's triangle ...?

jenyasd209 [6]

Using row 4:

coefficients are: 1, 4, 6, 4, 1 

a^4 + a^3b + a^2b^2 + ab^3 + b^4 

Now adding the coefficients: 

1a^4 + 4a^3b + 6a^2b^2 + 4ab^3 + 1b^4 

Substitute a and b: 

a = 4x 

b = -3y 

1(4x)^4 + 4(4x)^3(-3y) + 6(4x)^2(-3y)^2 + 4(4x)(-3y)^3 + 1(-3y)^4 

Now simplify the above: 

256x^4 - 768x^3y + 864x^2y^2 - 432xy^3 + 81y^4

Vaughn Manufacturing has three product lines. Its only unprofitable line is Corn Nuts, the results of which appear below for 201

elena-14-01-66 [18.8K]

Answer: The relevant costs are $18000 in the decision to eliminate this product line.

Step-by-step explanation:

Since we have given that

Sales = $1530000

Variable expenses = $1040000

Fixed expenses = $600000

Net loss = $110000

If product line is eliminated, 30% of the fixed expenses can be eliminated.

So, it becomes,

30% of $600000 is given by

$0.3\times 600000\\\\=\$18000$

Hence, the relevant costs are $18000 in the decision to eliminate this product line.
