Write a polynomial function in standard form
Vikentia [17]

Answer:

P(x) = x³-(3i+1)x²+(3i-2)x+6i

Step-by-step explanation:

If -1, 2 and 3i are roots of the polynomial, then the following are factors of the polynomial in x

(x+1), x-2 and x-3i

To get the required polynomial, we will take the product of the factors as shown;

(x+1)(x-2)(x-3i)

(x+1)(x-2) = x²-2x+x-2

(x+1)(x-2) = x²-x-2

(x²-x-2)(x-3i) = (x²)(x)-x²(3i)-x(x)-x(-3i)-2x-2(-3i)

(x²-x-2)(x-3i) = x³-3x²i-x²+3xi-2x+6i

(x²-x-2)(x-3i) = x³-x²(3i+1)+x(3i-2)+6i

(x²-x-2)(x-3i) = x³-(3i+1)x²+(3i-2)x+6i

Hence the polynomial function in standard form with leading coefficient of 1 is x³-(3i+1)x²+(3i-2)x+6i

Here are the ingredients for making fish pie for 6 people.
yarga [219]
Clare would need 80 of fish, (1/3 of 240 is 80.)
Ian would need 200g of butter (If you find the amount of each ingredient needed for a one person-pie, and multiply them by the amount of people you need to feed, you will get your answer.)
We know that 80g of butter is used for 6 people, so by dividing 80 by 6, we know that for a one person-pie, you would need 13.33g of butter. Multiply 13.33 by 15 to find out how many grams of butter he would need for a pie for 15 people.

Jane cycles 27km at 12m/h. How long does she take?
emmainna [20.7K]
Every hour at 12km/h I would go 12km. Simple.

The distance traveled in km is equal to 12 times how many hours you go.

If I go 27 km, I can go in reverse and divide by 12 to get 2.25 hours.

A quarter of an hour is 15 minutes, so the answer would be 2 hours and 15 minutes.
