for p(x)= 192 + 21x^3 + 54x^2 - 3x^4 - 264x, use synthetic substitution to evaluate p(1), p(-2), and p(8)
RSB [31]

The value of p(1), p(-2), and p(8) is 0, 744 and 0 respectively

<h3>What is polynomial function?</h3>

Given the function p(x)= 192 + 21x^3 + 54x^2 - 3x^4 - 264x

We are to get the following parameters:

p(1)= 192 + 21(1)^3 + 54(1)^2 - 3(1)^4 - 264(1)\\p(1)=192+21+54-3-264\\p(1)=0

For p(-2)

p(-2)= 192 + 21(-2)^3 + 54(-2)^2 - 3(-2)^4 - 264(-2)\\p(-2)=192-168+216-24+528\\p(-2)=744

For p(8)

p(8)=192 + 21(8)^3 + 54(8)^2 - 3(8)^4 - 264(8)\\p(8)=192+10,752+3,456-12,288-2,112\\p(-2)=0

Hence the value of p(1), p(-2), and p(8) is 0, 744 and 0 respectively

Find a5, when a1 =4, r=5
sasho [114]

Answer:

Answer: a5 = 2500

Step-by-step explanation:

For a geometric sequence:  

First term = a0  

Second term = a1 = a0*r  

Third term = a2 = a0*r^2  

Fourth term = a3 = a0*r^3  

....  

nth term = a(n-1) = a0*r^(n-1)  

Given: a1 = 4 = a0*r  

Also: r = 5  

So, a0*5 = 4 => a0 = (4/5)  

a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500  


Hope this helps

correct me if im wrong☺

What is the answer to 0 &gt; 3x - 3 - 6?
swat32

Answer:

3 = x

Step-by-step explanation:

0 > 3x - 3 - 6

You want to group up the -3 and -6 first

0 > 3x - 9

Then you want to add 9 to each side to cancel out the negative 9 on one side.

0 > 3x - 9

+9        +9

9 > 3x

Now you just divide by 3 on each side

\frac{9 = 3x}{3}

3 = x
