Answer:

x = 20.6°

using cosine rule:

$\sf cos(x)= \dfrac{adjacent}{hypotensue}$

<u>using the formula:</u>

$\sf cos(61)= \dfrac{10}{x}$

$\sf x= \dfrac{10}{cos(61)}$

$\sf x= 20.6$

Which of the following best describes the graph below?

<h3>Answer: B.) it is a one-to-one function</h3>

Explanation:

It's a function because it passes the vertical line test. It's also one-to-one because it passes the horizontal line test.

The vertical line test is where we try to draw a single line through more than one point on the blue curve. Such a task isn't possible in this case, and we consider the curve passing the vertical line test. The horizontal line test is nearly identical, but we're dealing with horizontal lines of course.

Select the two binomials that are factors of this trinomial.

mojhsa [17]

To split this trinomial into two binomials, let's try and find two numbers which add to 6 and multiply to 8. To do this, we can list all the factors of 8 and then choose which factors also add to 6.

Factors of 8: (1, 8), (2, 4)

1 + 8 = 9, meaning that 1 and 8 are not the factors we are looking for. However, 2 and 4 do add to 6. By combining these numbers which an x (so that we can produce the $x^2$ term at the front of the trinomial), we find the binomials:
