Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s
sergey [27]

Answer:

y = x⁴ − 9x² − 50x − 150

Step-by-step explanation:

Complex roots come in conjugate pairs.  So if -1 + 3i is a root, then -1 − 3i is also a root.

y = (x − 5) (x + 3) (x − (-1 + 3i)) (x − (-1 − 3i))

y = (x − 5) (x + 3) (x + 1 − 3i) (x + 1 + 3i)

Distribute using FOIL (first, outer, inner, last) to get real coefficients:

y = (x − 5) (x + 3) (x² + (1 + 3i)x + (1 − 3i)x + (1 − 3i)(1 + 3i))

y = (x − 5) (x + 3) (x² + x + 3ix + x − 3ix + 1 + 3i − 3i − 9i²)

y = (x − 5) (x + 3) (x² + 2x + 1 + 9)

y = (x − 5) (x + 3) (x² + 2x + 10)

Distribute to convert from factored form to standard form:

y = (x² + 3x − 5x − 15) (x² + 2x + 10)

y = (x² − 2x − 15) (x² + 2x + 10)

y = x²(x² + 2x + 10) − 2x(x² + 2x + 10) − 15(x² + 2x + 10)

y = x⁴ + 2x³ + 10x² − 2x³ − 4x² − 20x − 15x² − 30x − 150

y = x⁴ − 9x² − 50x − 150

Adam is buying a jacket that regularly costs $120 if he receives a 20% discount and there is a 6.25% tax what is the final price
Makovka662 [10]

Answer:

Step-by-step explanation:

Jacket multiplied by 20 percent

$120.00 x .20 = 24

Jacket minus the answer

$120 - 24 =96

New cost of jacket is $96

Now multiply that by 6.25% tax

$96 x 6.25 = 6.00

Add the sales tax to cost of jacket

$96.00 + 6.00 = $102.00

A car rental agency rents cars for $26.20 per day plus $0.35 per mile driven. Your travel budget is $200. Write an inequality th
laila [671]

For this case we have to:

x: Represents the number of miles that can be traveled in a day

We have that the cost of daily car rental is given by the following expression:

26.20 + 0.35x

If the person has a budget of $200 then we have to:

26.20+0.35x\leq200\\0.35x\leq200-26.20\\0.35x\leq173.8\\x\leq\frac{173.8}{0.35}\\x\leq496.57

Thus, you can travel 496 miles in one day.

Answer:

26.20 + 0.35x \leq200
