The period of f(x)=cos (2pi/3)x is ...?

1 answer:

5 0

Well lets see. if you're being specific about the rigor, then the period means that cos(2Π÷3(x+α))=cos(2Π÷3(x))Therefore this gives 2π÷3α=2πso α = 3.
Hope this can help you

Hello there!☺

$Answer:\boxed{(2x+3)(x+1)}$

$Explanation:$

$2x^2+5x+3$ Factorized

To factor $2x^2+5x+3$ , we will have to do it by grouping.

$2x^2+5x+3\\(2x+3)(x+1)$

$(2x+3)(x+1)$ is your answer.

Hope this helps!☺

What is the completely factored form of d4 − 81?

lilavasa [31]

For this case we must factor the following expression:

$d ^ 4-81$

Rewriting the expression:

$(d ^ 2) ^ 2-9 ^ 2$

We factor using the formula of the square difference:

$a ^ 2-b ^ 2 = (a + b) (a-b)$

Where:

$a = d ^ 2\\b = 9$

So:

$(d ^ 2 + 9) (d ^ 2-9)$

From the second term we have:

$d ^ 2-3 ^ 2 = (d-3) (d + 3)$

Finally, the factored expression is:

$(d ^ 2 + 9) (d-3) (d + 3)$

Answer:

$(d ^ 2 + 9) (d-3) (d + 3)$
