Give an example of a polynomial that is a perfect square. How do you know that it is a perfect square? Give its factored form.

lora16 [44]

Answer:

Step-by-step explanation:

A polynomial is a perfect square if has the form:

$a^2+2ab+b^2$

Its factored form is $(a+b)^2$ .

We can obtain examples by taking any value of a and b.

For example:

$a=x$ anb $b=2y$ .

Thus we obtain a polynomial that is a perfect square:

$x^2+2(x)(2y)+(2y)^2=x^2+4xy+4y^2$

I have another question I need help with. How do I solve for the missing angle?

Oksanka [162]

Answer:

The angle measures approximately 18.19°.

Step-by-step explanation:

Since we want to find the angle and we are given the side adjacent to the angle and the hypotenuse, we can use the cosine ratio. Recall that:

$\displaystyle \cos \theta = \frac{\text{adjacent}}{\text{hypotenuse}}$

The adjacent side is 19 and the hypotenuse is 20. Substitute:

$\displaystyle \cos \theta = \frac{19}{20}$

We can take the inverse cosine of both sides:

$\displaystyle \theta = \cos^{-1}\frac{19}{20}$

Use a calculator (make sure you're in Degrees Mode!). Hence:

$\theta \approx 18.19^\circ$

The angle measures approximately 18.19°.

Hello!

8y + 3 > 15y + 52 <=>

<=> 8y - 15y > 52 - 3 <=>

<=> -7y > 52 - 3 <=>

<=> -7y > 49 <=>

<=> y < -7 => y ∈ { -∞; -7 }

Good luck! :)
