Answer:

22.0

Step-by-step explanation:

knowing the radius is 3.5 -

and the formula for the circumfrence -

2 pi r

we can then use the radius -

2 * 3.14 * 3.5

which is 21.98 -

rounding to 22.0

hope this helps!!

Identify two methods a person can use to pay their bills online. Explain the advantages and disadvantages of both methods.
jek_recluse [69]
1) You can pay your bills online using your debit, credit card, or an electronic check. Advantage: you pay when you want and when you are sure you have money in the bank. Disadvantage: you have to remember to pay the bills by the due date.

2) You can set up automatic withdrawal from your bank account to pay your bills. Advantage: once you set it up, you do not have to remember to pay the monthly bills. Disadvantage: if you do not check your checking account balance to be sure there is enough money to cover the bills, your account may go negative.

Hope this helps! :)

What is the product of -2x^3+x-5 and x^3-3x-4 ? (a) Show your work
saul85 [17]

Answer:

-3x3 - 2x - 4

Step-by-step explanation:

 ((((2•(x3))+x)-5x3)-3x)-4

 (((2x3 +  x) -  5x3) -  3x) -  4

Pulling out like terms :

4.1     Pull out like factors :

  -3x3 - 2x - 4  =   -1 • (3x3 + 2x + 4)

Polynomial Roots Calculator :

4.2    Find roots (zeroes) of :       F(x) = 3x3 + 2x + 4

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  3  and the Trailing Constant is  4.

The factor(s) are:

of the Leading Coefficient :  1,3

of the Trailing Constant :  1 ,2 ,4

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        -1.00    

     -1       3        -0.33        3.22    

     -2       1        -2.00        -24.00    

     -2       3        -0.67        1.78    

     -4       1        -4.00        -196.00    

     -4       3        -1.33        -5.78    

     1       1        1.00        9.00    

     1       3        0.33        4.78    

     2       1        2.00        32.00    

     2       3        0.67        6.22    

     4       1        4.00        204.00    

     4       3        1.33        13.78    

Polynomial Roots Calculator found no rational roots

Final result :

 -3x3 - 2x - 4
