Find the slope from the given points (-5,3) (2,4)

Alecsey [184]

Answer:1/7

(-5,3)= (x1,y1)

(2,4)= (x2,y2)

Slope= $\frac{y2-y1}{x2-x1}$

= $\frac{4-3}{2-(-5)}$

= $\frac{1}{7}$

A single cell can either die, with probability .1, or split into two cells, with probability .9, producing a new generation of c

FinnZ [79.3K]

<span>A single cell can die, with probability .1

So, the probability distribution for next generation, P(a cell can die) = 1/10

</span>A single cell can split into two cells,, with probability .9

So, the probability distribution for next generation, P(a cell can split into two cells) = 9/10

Which equation has exactly two real and two non real solutions?

tatiyna

Answer:

The first option $x^4-21x^2-100=0$ .

Step-by-step explanation:

To have exactly 2 real and two non real solutions, the degree of the polynomial must be a degree 4. Degree is the highest exponent value in the polynomial and is also the number of solutions to the polynomial. This polynomial ha 2 real+2 non real= 4 solutions and must be $x^4$ . This eliminates the bottom two solutions.

In order to have two real and two non real solutions, the polynomial must factor. If it factors all the way like

$x^4-100x^2=0\\x^2(x^2-100)=0\\x^2(x-10)(x+10)=0\\\\x^2=0\\x-10=0\\x+10=0$

This means x=0, 10, -10 are real solutions to the polynomial. It has no non real solutions. This eliminates this answer choice.

Only answer choice 1 meets the requirement.
