Yo sup??

To solve this problem u just need the basics of trigonometry

So

Sinx=opposite side/hypotenuse

Cosx=adjacent side/hypotenuse

Tanx=sinx/cosx=opposite/adjacent

Now just plug in the values

Sinx=2√3/4

=√3/2

Cosx=2/4

=1/2

Tanx=√3

If u had a better knowledge of trigonometry then u will find that x is 60° or π/3

Hope this helps

kicyunya [14]

Answer:

Original price of bicycle = $864

Step-by-step explanation:

Given:

Rate of tax = 20%

Price pay by Mathew = $1,080

Find:

Original price of bicycle

Computation:

Original price of bicycle = Price pay by Mathew[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-20%)]

Original price of bicycle = 1,080[1 / (1-0.2)]

Original price of bicycle = 1,080[1 / (0.8)]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = 1,080[1.25]

Original price of bicycle = $864

Which is the graph of the function f(x) = x2 + 2x + 3?
blagie [28]
Dy/dx=2x+2

So velocity will be zero when 2x+2=0, x=-1

Since d2y/dx2=2, it has a constant positive acceleration of 2, so that when dy/dx=0 it is at an absolute minimum value for f(x), which is also the vertex.

y(-1)=1-2+3=2

So the vertex is at (-1,2), which is an absolute minimum so the parabola opens upwards.

And by symmetry we can say that f(0)=f(-2)=3 so you have another two points that you can see (-2,3) and (0,3)
