Find cos ⁡ ( 2 ⋅ ∠ A B C ) cos(2⋅∠ABC)
Pavlova-9 [17]

The value of the cosine function is -0.385

<h3>How to determine the measure of the cosine function?</h3>

The figure that completes the question is added as an attachment

From the figure, we have the following sides

AB = √13

AC  = 3

BC = 2

The triangle is a right triangle.

The angle B is calculated as:

cos(B) = 2/√13

Evaluate

cos(B) = 0.5547

Take the arccos of both sides

B = 56.31

This means that:

cos(ABC) = cos(56.31)

Multiply ABC by 2.

So, we have:

cos(ABC * 2) = cos(56.31 * 2)

Evaluate the product

cos(ABC * 2) = cos(112.62)

Evaluate the cosine

cos(ABC * 2) = -0.385

Hence, the value of the cosine function is -0.385

PLEASE HELP ASAP!!(SHOW ALL STEPS)<br><br> Determine the factors<br> x2y + 3x2 + 3y + 9
krok68 [10]

Answer:

(y+3) (x^2+3)

Step-by-step explanation:

x^2y + 3x^2 + 3y + 9

I will factor by grouping

Taking the first two terms I can factor out x^2

Taking the last two terms I can factor out 3

x^2y + 3x^2     + 3y + 9

x^2(y+3)           + 3(y+3)

Now I can factor out (y+3)

(y+3) (x^2+3)

Since(x^2+3) and (y+3) cannot be factored , this is completely factored
