Q is a degree 5 polynomial that passes through the origin, has zeros i and 7 - i, and q(-1)= -520. find the equation for q

Lunna [17]

Using the factor theorem, the equation for q is:

$q(x) = 4(x^5 - 14x^4 + 51x^3 - 14x^2 + 50x)$

The Factor Theorem states that a polynomial function with roots $x_1, x_2, ..., x_n$ is given by:

$f(x) = a(x - x_1)(x - x_2)...(x - x_n)$

In which a is the leading coefficient.

In this problem:

Passes through the origin, so x = 0 is a zero, that is $x_1 = 0$ .
x = i is a zero, and thus, it's conjugate also is, that is, x = -i, hence $x_2 = i, x_3 = -i$

x = 7 - i is a zero, and thus, it's conjugate also is, that is, x = 7 + i, hence $x_4 = 7 - i, x_3 = 7 + i$

Then, the equation is:

$q(x) = a(x - 0)(x - i)(x + i)(x - 7 + i)(x - 7 - i)$

$q(x) = ax(x^2 - i^2)((x-7)^2 - i^2)$

Considering that $i^2 = -1$

$q(x) = ax(x^2 + 1)(x^2 - 14x + 50)$

$q(x) = ax(x^4 - 14x^3 + 51x^2 - 14x + 50)$

$q(x) = a(x^5 - 14x^4 + 51x^3 - 14x^2 + 50x)$

q(-1) = -520 means that when $x = -1, q = -520$ , and this is used to find a.

$q(x) = a(x^5 - 14x^4 + 51x^3 - 14x^2 + 50x)$

$-520 = a(-1 - 14 - 51 - 14 - 50)$

$130a = 520$

$a = \frac{520}{130}$

$a = 4$

Hence, the equation is:

$q(x) = 4(x^5 - 14x^4 + 51x^3 - 14x^2 + 50x)$

If g(x)=x2-5x+7 find g(2) a.-13 b.21 c.5 d.1

aksik [14]

If you would like to find g(2), you can do this using the following steps:

g(x) = x^2 - 5x + 7
g(2) = 2^2 - 5 * 2 + 7 = 4 - 10 + 7 = 1

The correct result would be d. 1.

Find the component form of v given its magnitude and the angle it makes with the positive x-axis. Round to the nearest thousandt

Lostsunrise [7]

Answer:

see below

Step-by-step explanation:

||v|| = 3/4

Theta = 30 degrees

The x component is x = ||v|| cos theta

= 3/4 cos 30 =3/4 * sqrt(3) /2 =3 /8 sqrt(3) =.649519053= .650

The y component is y = ||v|| sin theta

= 3/4 sin 30 =.375
