How to solve this? Don't just give me the answer help me learn this.
Sphinxa [80]

Answer:

I'm not entirely sure but I think that what is says is that it wants you to find the value of x in (4x+28) to make it 116 degrees because it is that same angle. So what you do is you get (4x+28)=116 and you do this because they are the same angle so you use 116 and get it to solve x. Since I'm lazy, then I go to this website and type the equation in: m a t h w a y . c o m but without all of the spaces, I had to do that so it would let me answer this, but I'll do it the real way this time. (4x+28)=116  Their is a rule in math that as long as you do something to one side of the equal sign in the equation, you have to do it to the other and it will still work. So, you minus 28 from both sides so that you can get rid of it and you now have 4x=88. Now you should know this part but you divide 4 from both sides to make so x is alone. Now you have x=22 because you divided 4 from each side. So their is your answer: x=22.

Step-by-step explanation: If you have the answer key that you can check from to make sure you got it right because I know some teachers let you do that, then you should make sure that is right, but I am pretty sure it is.

Misha Larkins [42]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value is  y  =  5sin3x

Step-by-step explanation:

From the question we are told that  

   y =  c_1\ cos3x + c_2 \  sin 3x

given that y(0) =  0

We have that  

     c_1\ cos3(0) + c_2 \  sin 3(0)  =  0

=>   c_1 =  0

This means that

           y  =  c_2 \  sin 3x

We also given that

          y[\frac{\pi}{6} ] =  5

So  

         c_2  sin (3 *  \frac{\pi}{6} )  =  5

=>    c_2  =  5

Hence  

     y  =  5sin3x

Write the Equation of the line that has a slope of -2 and passes through the points (9,5)
AlladinOne [14]

Start with the point-slope formula shown at the top in red.

Now, substitute your slope and coordinates in the formula.

Then distribute and combine lie terms.

Finally, add 2x to both sides to get your equation in standard form.
