Write a polynomial function for f(2)=0 with a multiplicity of 2 and f(-1)=0
nevsk [136]

We have the following:

Being a multiplicity of two, then we only have to multiply two factors

We must create a polynomial that, like 0, its solution is 2 and that is -1, in the following way

\begin{gathered} x=2\Rightarrow x-2=0 \\ x=-1\Rightarrow x+1=0 \\ \text{ we multiply the factors} \\ (x-2)\cdot(x+1)=0 \\ x^2+x-2x-2=0 \\ x^2-x-2=0 \end{gathered}

Therefore, the answer is the option d.

f(x)=x^2-x-2

. What is 6 8ths x 5? Draw a model of your choice to help you solve.<br><br> WILL GIVE BRAINIST
professor190 [17]

Answer:

The complete and simplified answer to the question what is 6/8 of 5 is:  

3 3/4

Step-by-step explanation:

You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.

Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator: 5/1

So now that we've converted 5 into a fraction, to work out the answer, we put the fraction 6/8 side by side with our new fraction, 5/1 so that we can multiply those two fractions.

That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look:

 

6 x 5/ 8 x 1  =  30 /8

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 30 and 8 is 2.

We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.

30/2 = 15

8/2 = 4

When we put that together, we can see that our complete answer is:  

15/ 4

 

If you now simplifiy the COMPLETE anwser is:

3 3/4
