Answer:
n = 120i + 310j + 60k
p = 29i + 18j + 21 k
Total cost = $10,320
Step-by-step explanation:
Let n and p represent the vectors for number of products and prices respectively.
Also, the coordinates i,j and k represent cashews, walnut and Brazil nut respectively.
The vector form of the total number of bags ordered and the cost are;
n = 120i + 310j + 60k
p = 29i + 18j + 21 k
We can obtain the total cost by obtaining the dot product of the two vectors.
Total cost = n.p = (120i + 310j + 60k).(29i + 18j + 21 k)
C = 120×29 + 310×18 + 60×21
C = $10,320
R=120 mm
diameter 240
so your answer is 120mm

<u>Factored Form Of Polynomials
</u>
If we know the roots of a polynomial as

the polynomial can be expressed in factored form as

We are given two of the three roots of the polynomial:


The other root must be the conjugate of the complex root:

Recall the product of two complex conjugate numbers is

The required polynomial is
![P(x)=a\left[ x-(1-3i)\right ]\left[ x-(1+3i)\right ](x-2)](https://tex.z-dn.net/?f=P%28x%29%3Da%5Cleft%5B%20x-%281-3i%29%5Cright%20%5D%5Cleft%5B%20x-%281%2B3i%29%5Cright%20%5D%28x-2%29)

This is the factored form of the polynomial where only real numbers appear
We need to find the value of a, such as



Thus the value of a is

The expression of the required polynomial is
