Answer: cos(F)=\frac{5}{13}

Step-by-step explanation:

The trigonometric identity needed to answer this question is:

cos\alpha=\frac{adjacent}{hypotenuse}

Therefore:

Indentify the angle, the opposite side and the adjacent side of the right triangle from the figure:

adjacent=5\\hypotenuse=13\\\alpha=F

Substitute them intocos\alpha=\frac{adjacent}{hypotenuse}, then we get:

cos(F)=\frac{5}{13}

Answer:

5/13

Step-by-step explanation:

Cosine ratio for an angle is defined as the ratio of Adjacent side to Hypotenuse.

We have to find the cosine ratio for angle F. The side adjacent to angle F is side GF and the hypotenuse of the triangle is side FH. The side opposite to the right angle is always the hypotenuse.

So, we can write:

\textrm{Cosine Ratio}=\frac{Adjacent}{Hypotenuse}\\\\ \textrm{Cosine Ratio of F}=\frac{FG}{FH} \\\\ \textrm{Cosine Ratio of F}=\frac{5}{13}

Therefore, the cosine ratio of angle F is 5/13

What is the product?<br><br> 2x(x – 4)
sashaice [31]

Keywords:

<em>Product, factors, polynomial, distributive property </em>

For this case we must find the product of two factors of a polynomial. To do this, we must apply the distributive property, which states: a (b + c) = ab + ac.

So:

2x (x - 4) = 2x * x-2x * 4\\2x (x - 4) = 2x ^ 2-8x

Thus, the product of 2x (x - 4) is: 2x ^ 2-8x

Answer:

The product of 2x (x - 4) is: 2x ^ 2-8x
