Find the exact value of the indicated trigonometric function of θ.
Mariana [72]

Answer:

cosθ = -√(35/36)

tanθ = -1/√35

Step-by-step explanation:

We know that

sin²θ + cos²θ = 1

(1/6)² + cos²θ = 1

1 - (1/6)² = cos²θ

35/36 = cos²θ

sec θ = 1/ cosθ

1/ secθ = cos θ

Because secθ < 0, 1/ secθ would also be < 0, so cos θ < 0

cosθ = -√(35/36)

tanθ = sinθ/cosθ = (1/6)/-√(35/36)

= (1/6) / -(√35/6)

= -1/√35

Answer:

Choice D.

Step-by-step explanation:

The range is the set of all y-coordinates of the points in the graph.

The graph is a wavy function that has a maximum y-coordinate of 1 and a minimum y-coordinate of -1. The y-coordinates can also be all numbers between -1 and 1. Choice A. is only the two numbers -1 and 1. That is not correct since the range comprises the numbers -1, 1, and all numbers in between -1 and 1.

<span> For this case we can make the following rule of three:
 2.99 ----------> 100%
 x --------------> 7%
 From here, we clear the value of x.
 We have then:
</span> x = (7/100) * (2.99)&#10;
<span> Rewriting the expression we have:
</span> x = (0.07) * (2.99)&#10;&#10;x = 0.2093 $<span>
