Pls show work. 3.14 for pi
stepan [7]
The easiest way to do this is to split each figure into smaller shapes.  
1. a rectangle and a triangle
2. 3 separate rectangles
3. triangle and rectangle
... so on
You then find the areas of the smaller shapes and then add them together.
1. (for rectangle) 6*3 = 18
    (for triangle) (12*15)/2 = 90         90 + 18 = 108
2. 4*8 = 32
    8*4 = 32
    12*12 = 144           32 + 32 + 144 = 208
...so on

Phantasy [73]

Answer:

Step-by-step explanation:

2\sqrt{3} sin^{2} \alpha -cos\alpha =0\\2\sqrt{3} (1-cos ^2 \alpha )-cos \alpha =0\\2\sqrt{3} -2\sqrt{3} cos^2 \alpha -cos \alpha =0\\2\sqrt{3} cos^2 \alpha +cos \alpha -2\sqrt{3} =0\\cos \alpha =\frac{-1 \pm\sqrt{1^2-4*2\sqrt{3}*(-2\sqrt{3})  } }{2*2\sqrt{3} } \\=\frac{-1 \pm\sqrt{1+48} }{4\sqrt{3} } \\=\frac{-1\pm7}{4\sqrt{3} } \\either~cos \alpha =\frac{6}{4\sqrt{3} }=\frac{\sqrt{3} }{2} \\=cos \frac{\pi }{6} ,cos(2\pi -\frac{\pi }{6} )\\=cos \frac{\pi}{6} ,cos \frac{11\pi }{6}

\alpha =2 n\pi+ \frac{\pi }{6} ,2n\pi +\frac{11\pi }{6} (general~solution)

or~cos\alpha =-\frac{7}{4\sqrt{3} } \\ \alpha =cos^{-1}( \frac{-7}{4\sqrt{3} } )

Can someone please answer all parts?? Extra points for this one!

     <span>a) 
Acceleration of stone = 10 

Integrate: 
So velocity = 10t 

Integrate again: 
So distance from starting point = 5t^2 

Distance from ground = 450-5t^2 

b) 
450 - 5t^2 = 0 


9.48 seconds 

c) velocity = 10t 

Put the time into this to give: 

94.8 m/s 

d. 

Velocity = 10t + 5 

Integrate again: 

5t^2 + 5t 


Solve 
5t^2 + 5t = 450 

Gives 9 seconds</span>
