Answer:

D

Step-by-step explanation:

Since Θ is in the fourth quadrant where cosΘ > 0

The only positive values are B / D

since 0 < cosΘ < 1

\frac{\sqrt{41} }{5} > 1 then

D is the appropriate response

Answer:

Step-by-step explanation:

sin2x = 2sinx*cosx

         = 2\sqrt{sin^{2}x } * cosx

         = 2\sqrt{(1-cos^{2}x } * cosx

         = 2  \sqrt{1-\frac{3}{5} ^{2} } *\frac{3}{5}

         = \frac{8}{5}  * \frac{3}{5}  

         = 24/25

Solve for y <br> 6x - 2y = 12<br> A. y= -3x + 6<br> B. y= 3x - 6<br> C. -3x + 6<br> D. -3x - 6
ololo11 [35]
The answer is y=3x-6. (B). First you subtract 6x from both sides. Then you get -2y=12-6x. Now, you divide both sides by -2. This gets you the final answer; y=3x-6 or y=-6+3x.

The table shows temperatures below freezing measured in different units. Complete the equation in standard form to represent the
dezoksy [38]

The relationship between the temperature in celsius to the temperature in Fahrenheit is C = (5/9)(F - 32)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let F represent temperature measured in degrees Fahrenheit, and C, a temperature measured in degrees Celsius.

At 0°C, the temperature is 32°F. Also at 100°C, the temperature is 212°F, hence:

C-0=\frac{100-0}{212-32} (F-32)\\\\C=\frac{5}{9} (F-32)

The relationship between the temperature in celsius to the temperature in Fahrenheit is C = (5/9)(F - 32)
