Answer: The answer is given below.

Step-by-step explanation: We are given to find the multiplicity of the roots of the following equation:

$k(x)=x(x+2)^3(x+4)^2(x-5)^4.$

We can clearly say that the roots of the above equation are 0, -2, -4 and 5.

The power of (x-0) is 1, so the multiplicity of 0 is 1.

The power of (x+2) is 3, so the multiplicity of -2 is 3.

The power of (x+4) is 2, so the multiplicity of -4 is 2.

The power of (x-5) is 4, so the multiplicity of 5 is 4.

Hence completed.

Answer:

y -1 = -1(x -2)

Step-by-step explanation:

The slope of the line through the two points can be found from the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (5 -1)/(-2 -2) = 4/-4 = -1

The point-slope equation for a line through point (h, k) with slope m is ...

y -k = m(x -h)

You have (h, k) = (2, 1) and m = -1. Putting these values into the form gives ...

y -1 = -1(x -2)

<em>Additional comment</em>

Your problem statement already has two of the three values filled in, so you only need to enter the x-coordinate of the first point: 2.

The line AB has midpoint (2,5).<br> A has coordinates (1, 2).<br> Find the coordinates of B.

Gekata [30.6K]

Answer:

$X_m = \frac{A_x +B_x}{2}= \frac{1+B_x}{2}= 2$

And we can solve for $B_x$ and we got:

$1+B_x = 4$

$B_x = 3$

$Y_m = \frac{A_y +B_y}{2}= \frac{2+B_y}{2}= 5$

And we can solve for $B_x$ and we got:

$2+B_y = 10$

$B_y = 8$

So then the coordinates for B are (3,8)

Step-by-step explanation:

For this case we know that the midpoint for the segment AB is (2,5)

And we know that the coordinates of A are (1,2)

We know that for a given segment the formulas in order to find the midpoint are given by:

$X_m = \frac{A_x +B_x}{2}= \frac{1+B_x}{2}= 2$

And we can solve for $B_x$ and we got:

$1+B_x = 4$

$B_x = 3$

$Y_m = \frac{A_y +B_y}{2}= \frac{2+B_y}{2}= 5$

And we can solve for $B_x$ and we got:

$2+B_y = 10$

$B_y = 8$

So then the coordinates for B are (3,8)

Cole rode his bike twice as far as Anita did today. Is this situation modeled by an expression or equation? How do you know?

Over [174]

Answer:

equation

Step-by-step explanation:

Let X is the distance that Anita rode

Let Y is the distance that Cole rode

Cole rode his bike twice as far as Anita, which mean:

Y = 2X

So this situation modeled by an equation
