Give a third degree polynomial that has zeros of 13, 5i, and −5i, and has a value of −680 when x=3. Write the polynomial in stan
Vikki [24]

Answer:

\dfrac{17x^3-221x^2+425x-5525}{9}\\

Step-by-step explanation:

hello

we need to find something like, a being real

a(x-13)(x-5i)(x+5i)

with a so that

a(3-13)(3-5i)(3+5i)=-680\\\\a(-10)(3^2-(5i)^2)= -10(9+25)a=-360a=-680\\ a = \dfrac{680}{360}=\dfrac{17*40}{9*40}=\dfrac{17}{9}

so the third degree polynomial that we are looking for is

\dfrac{17}{9}(x-13)(x-5i)(x+5i)\\=\dfrac{17}{9}(x-13)(x^2+25)\\\\=\dfrac{17}{9}(x^3+25x-13x^2-13*25)\\\\\\=\dfrac{17}{9}(x^3-13x^2+25x-325)\\\\\\\\=\dfrac{17}{9}x^3-\dfrac{17*13}{9}x^2+\dfrac{17*25}{9}x-\dfrac{17*325}{9}\\=\dfrac{17}{9}x^3-\dfrac{221}{9}x^2+\dfrac{425}{9}x-\dfrac{5525}{9}\\

hope this helps

What is the measure of bc if b is a midpoint? 4x-5 & 11 + 2x please help asap!
Bad White [126]

Answer:

<em>BC =  27</em>

Step-by-step explanation:

The point B is the midpoint of AC

=> AB = BC

=> 4x - 5 = 11 + 2x

Let's calculate x to work out BC

Transferring the components containing x to the left side, and other components to the right side:

=> 4x - 2x = 11 + 5

Simplifying both sides:

=> 2x = 16

=> x = 8

Working out BC:

=> BC = 11 + 2x = 11 + 2(8) = 11 + 16 = 27

Hope this helps!
