<h2>Answer: 1250</h2>

Step-by-step explanation:

- Since we go by PEMDAS (please excuse my dear aunt sally, or parenthesis, exponent, multiplication, division, addition, and subtraction) and there are no parenthesis, we see there is an exponent in this equation

To solve for an exponent multiply a number however many times the exponent tells you to... In this case 5^4 would be the same as:

5 x 5 x 5 x 5, which is equal to 625.

- From there, multiply 625 x 2 to get 1250 because Multiplication comes next in Order of Operations/PEMDAS

If f(x) = 3x3 + 5x2 + x - 1, what would be the P/Q list of possible rational roots?

aivan3 [116]

Answer:

1,-1,3,-3

Step-by-step explanation:

your P is the first number or the number with the highest exponent, your Q is the last number or the number with no variables. So you make a list of what multiplies to your P's and what multiplies to your Q's and you divide your P list by Q. So 3 is made by -1,1,-3,3 and -1 is made by -1,1. So dividing that you get your list of -3,-1,1,3

A sequence is created from the function k(n) = 2n + 3, where n represents the position of the term of the sequence. The sequence

pashok25 [27]

Substitute the n value into the equation. The n repersents the 'nth' term.
K (1) = 2(1) + 3
K = 5
Therefore, when n = 1, K = 5
Same goes t any other term.

K (3) = 2(3) + 3
K = 9
So, when n = 3, K=9

Just keep applying the same rule. Also, make sure that you answer it with a sentence at the end. This should always help you and the marker see that you are confidence with your answer...

I hoped I helped out. Good luck. :)
