What is the multiple zero and multiplicity of f(x) = x3 + 10x2 + 25x?
elena-s [515]

Answer:

The multiple zero is x=-5.

The multiplicity is 2

Step-by-step explanation:

The given function is

f(x)=x^3+10x^2+25x

To find the zero of this function, we equate it to zero.

\Rightarrow x^3+10x^2+25x=0

We factor to obtain;

x(x^2+10x+25)=0

Observe that; the expression within the parenthesis is a perfect square.

This implies that;

x(x+5)^2=0

This implies that;

Either x=0 or (x+5)^2=0

(x+5)^2=0 has a multiple zero which is

x=-5 and its multplicity is 2.

Is y=6x-2 proportional
Alexus [3.1K]
Yes, the equation given above is proportional. The variables y and x are directly proportional to each other. <span>Two variables are proportional if a change in one is always accompanied by a change in the other, and if the changes are always related by use of a constant multiplier.</span>

Question 10
Anna11 [10]

Answer:

6,000 dollars

Step-by-step explanation:

We first need to find out how much it would cost Danielle for a month if she chose the second option

200 + 40 = 240

240 x 30 = 7,200

Now that we know how much Danielle would pay if she chose the second option, now we need to find out how much she <em>saved</em>.

7,200 - 1,200 = 6,000

So Danielle saved 6,000 dollars by choosing the first option instead of the second one.
