1 answer:

6 0

Rewriting input as fractions if necessary:
3/2, 3/8, 5/6, 3/1

For (2, 8, 6, 1) the least common multiple (LCM) is 24.

Therefore, the least common denominator (LCD) is 24.

Rewriting as equivalent fractions with the LCD:
36/24, 9/24, 20/24, 72/24

How to find imaginary zeros anf real zeros of F(x)=-4x^5-8x^3+12x

Fofino [41]

Answer:

$x=\{0, -1, 1, -i\sqrt{3}, i\sqrt{3}\}$

Step-by-step explanation:

We are given the function:

$f(x)=-4x^5-8x^3+12x$

And we want to finds its zeros.

Therefore:

$0=-4x^5-8x^3+12x$

Firstly, we can divide everything by -4:

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

Factor out an x:

$0=x(x^4+2x^2-3)$

This is in quadratic form. For simplicity, we can let:

$u=x^2$

Then by substitution:

$0=x(u^2+2u-3)$

Factor:

$0=x(u+3)(u-1)$

Substitute back:

$0=x(x^2+3)(x^2-1)$

By the Zero Product Property:

$x=0\text{ and } x^2+3=0\text{ and } x^2-1=0$

Solving for each case:

$x=0\text{ and } x=\pm\sqrt{-3}\text{ and } x=\pm\sqrt{1}$

Therefore, our real and complex zeros are:

$x=\{0, -1, 1, -i\sqrt{3}, i\sqrt{3}\}$

Is x = 2 a solution of the equation 8 - 5x = 3?* (5 Points) O Yes O No

kondaur [170]

Answer:

No sir

Step-by-step explanation:

first you will try to get x by its self.

so were it says -5x = 3 you wanna do

+5 +5 on both sides to cancel out 5 so that would be

X = 8 because -5 + 5 is 0 which in this case will be left with X

you already have 8 so x = 8

Hopefully this helps

About 9% of the population has a particular genetic mutation. 400 people are randomly selected. Find the mean for the number of

never [62]

Answer:

36 people

Step-by-step explanation:

The expected value E(X) = mean of sample = np

Where, p = population proportion, p = 9% = 0.09

n = sample size, = 400

The mean of the number of people with genetic mutation, E(X) = np = (400 * 0.09) = 36
