What polynomial has roots of -4, 1, and 6?

1 answer:

3 0

X^3-3x^2-22x+24
the first option is the answer

solution: (x + 4)(x - 1)(x -6) = (x^2 - x + 4x -4)(x - 6)
(x^2 + 3x -4)(x - 6) = x^3 -6x^2 + 3x^2 - 18x - 4x + 24 = x^3 - 3x^2 - 22x + 24

Solve the following equation for g: 2(g - h) = b + 4

DaniilM [7]

Answer:

g = $\frac{b+4+2h}{2}$

Step-by-step explanation:

Given

2(g - h) = b + 4 ← distribute parenthesis on left side

2g - 2h = b + 4 ( add 2h to both sides )

2g = b + 4 + 2h ( divide both sides by 2 )

g = $\frac{b+4+2h}{2}$

Given that f(x) = x^2 - 4x +1, find the value of m if f(m) = -3

iragen [17]

a. Answer: m = 2

<u>Step-by-step explanation:</u>

f(x) = x² - 4x + 1

f(m) = m² - 4m + 1 = -3

m² - 4m + 4 = 0

(m - 2)(m - 2) = 0

m = 2

***************************************************

b. Answer: k = 2 and k = 5

<u>Step-by-step explanation:</u>

f(x) = x² - 7x + 14

f(k) = k² - 7k + 14 = 4

k² - 7k + 10 = 0

(k - 2)(k - 5) = 0

k = 2 k = 5

If I varies inversely with R and I = 0.25 when R = 18, which equation should be used to show this relationship?

pashok25 [27]

Inverse relationships are of the form xy=k or if you prefer y=k/x so to find the constant we can say:

18(0.25)=k=4.5

So you could say: IR=4.5 or I=4.5/R
