Find all the zeroes of the polynomial function f(x)=x^3-5x^2+6x-30 in you use synthetic division show all three lines of numbers

jonny [76]

Answer:

5, $i\sqrt 6$ and $-i\sqrt 6$

Step-by-step explanation:

We are given that the polynomial

$f(x)=x^3-5x^2+6x-30$

We have to find the all the zeroes of the polynomial function.

$f(x)=0$

$x^3-5x^2+6x-30=0$

$x^2(x-5)+6(x-5)=0$

$(x-5)(x^2+6)=0$

$x-5=0$

$x=5$

$x^2+6=0$

$x^2=-6$

$x=\pm\sqrt{-6}=\pm i\sqrt6$

Using $\sqrt{-1}=i$

Hence, all the zeroes of the polynomial function are

5, $i\sqrt 6$ and $-i\sqrt 6$

What is the value of y in the solution to the following system of linear equations?

Leviafan [203]

ANSWER

$y=12$

<u>EXPLANATION</u>

One way is to make x the subject in one equation and substitute into the other.

$2x+2=y$

$\Rightarrow 2x=y-2$

$\Rightarrow x=\frac{y}{2}-1--(1)$

The second equation is

$2y=5x-1--(2)$

Let us put equation 1 in 2

$\Rightarrow 2y=5(\frac{y}{2}-1)-1$

$\Rightarrow 2y=\frac{5y}{2}-5-1$

$\Rightarrow 2y=\frac{5y}{2}-6$

Multiplying through by 2 gives;

$\Rightarrow 4y=5y-12$

$\Rightarrow 4y-5y=-12$

$\Rightarrow -y=-12$

$\Rightarrow y=12$

Answer:

Option D. $392.5\ units^{3}$

Step-by-step explanation:

we know that

The volume of the cone is equal to

$V=\frac{1}{3} \pi r^{2}h$

In this problem we have

$h=15\ units$

$r=5\ units$

substitute the values

$V=\frac{1}{3} (3.14)(5^{2})(15)=392.5\ units^{3}$
