Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s
Jobisdone [24]

Answer:

f(x)=x^4-9x^2-50x-150

Step-by-step explanation:

Let f(x) be the polynomial function of minimum degree with real coefficients whose zeros are 5, -3, and -1 + 3i be f(x).

By the complex conjugate property of polynomials, -1-3i is also a root of this polynomial.

Therefore the polynomial in factored form is f(x)=(x-5)(x+3)(x-(-1+3i))(x-(-1+3i))

We expand to get:f(x)=(x^2-2x-15)(x^2+2x+10)

We expand further to get:\

f(x)=x^4-9x^2-50x-150

Pete has an old playstation that he bought for $400.
katrin2010 [14]

Answer:

1 year= $280

Step-by-step explanation:

30% of 400= 0.3 * 400= 120

400-120= 280

after one year the playstation cost 280

30% of 280= 0.3 * 280= 84

280-84= 196

after 2 years it cost $196

multiply the number by 0.3 to get 30% of the total

Strontium-90 has a half-life of about 29 years. After 65 years, about how many grams of a 25-gram sample will remain?
konstantin123 [22]

Answer:

Ending Amount = Beginning Amount / 2 ^ n

where 'n' = number of half-lives n = 65 / 29 = 2.2413793103

Ending Amount = 25 g / 2^2.2413793103

Ending Amount = 25 / 4.7284892286

Ending Amount = 5.2871009727  g = 5.29 g (rounded)
