Limit

STatiana [176]

Rationalize the numerator:

$\dfrac{\sqrt{x+4}-2}x\cdot\dfrac{\sqrt{x+4}+2}{\sqrt{x+4}+2}=\dfrac{(\sqrt{x+4})^2-2^2}{x(\sqrt{x+4}+2)}=\dfrac x{x(\sqrt{x+4}+2)}=\dfrac1{\sqrt{x+4}+2}$

This is continuous at $x=0$ , so we can evaluate the limit directly by substitution:

$\displaystyle\lim_{x\to0}\frac{\sqrt{x+4}-2}x=\lim_{x\to0}\frac1{\sqrt{x+4}+2}=\frac1{\sqrt4+2}=\frac14$

kkurt [141]

Answer:

Step-by-step explanation:

sec x( cotx + cos x )= csc x+ 1

1/cos x( cosx/ sinx +cosx) = csc x+ 1

1/cosx ( cosx + sinxcosx/sinx) = csc x+ 1

1/cosx( cosx) ( 1+sinx/sinx) = csc x+ 1

1(1/sinx+1) = csc x+ 1

cscx +1= = csc x+ 1

I don’t get this can someone explain this

LekaFEV [45]

Answer:

15.7 units

Step-by-step explanation:

AB = 6, BC = 3

Therefore by Pythagoras theorem

AC = $\sqrt{45}$

$perimeter \: of \: \triangle \: ABC \\ = 6 + 3 + \sqrt{45} \\ = 9 + 6.70820393 \\ = 9 + 6.7 \\ = 15.7\: units$
