Can someone help me find AB and BC
Bond [772]

  • 3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
  • 10x + 20 = 180 [combine like terms]
  • 10x = 160 [subtract 20 from both sides]
  • x = 16 [divide both sides by 10]

Arc AB measures 3(16) = 48 degrees.

Arc BC measures 2(16) + 5 = 41 degrees.

Find dy/dx using first principle<br>x+1/x​
JulsSmile [24]

Answer:

The derivative of the function is:

f'(x)=1-\frac{1}{x^{2}}

Step-by-step explanation:

The first principle is given by:

f'(x)=\frac{dy}{dx}=lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}

The function here is:

f(x)=x+\frac{1}{x}

Now, using the first principle we have:

f'(x)=lim_{h\rightarrow 0}\frac{(x+h)+\frac{1}{(x+h)}-x-\frac{1}{x}}{h}  

=lim_{h\rightarrow 0}\frac{h+\frac{1}{(x+h)}-\frac{1}{x}}{h}    

=lim_{h\rightarrow 0}\frac{h-\frac{h}{x(x+h)}}{h}    

=lim_{h\rightarrow 0}\frac{h(1-\frac{1}{x(x+h)})}{h}

=lim_{h\rightarrow 0}1-\frac{1}{x(x+h)}

=1-\frac{1}{x^{2}}

 

Therefore, the derivative of the function is:

f'(x)=1-\frac{1}{x^{2}}

I hope it helps you!
