Answer:

$AB=XY$

$BC=YZ$

$CA=ZX$

Step-by-step explanation:

we know that

If two figures are congruent, then its corresponding sides will be congruent

in this problem we have

$AB=XY$

$BC=YZ$

$CA=ZX$

Find the equation of the tangent line to the curve at the given point?

Over [174]

Answer:

The equation of the tangent line

$y - \frac{\pi }{4} = (\frac{-\pi }{2} +1)( x - \frac{\pi }{4} )$

Step-by-step explanation:

Step(i):-

Given function y = x cot (x) ....(i)

Differentiating equation (i) with respective to 'x' , we get

$\frac{dy}{dx} = x (-Co sec^{2} (x)) +cot(x) (1)$

Step(ii):-

The slope of the tangent line

$\frac{d y}{d x} = -x Co-sec^{2} (x) +cot x$

$(\frac{d y}{d x} )x_{=\frac{\pi }{4} } = -\frac{\pi }{4} Co-sec^{2} (\frac{\pi }{4} ) +cot \frac{\pi }{4}$

We will use trigonometry formulas

$Cosec(\frac{\pi }{4} ) = \sqrt{2}$

$sec(\frac{\pi }{4} ) = \sqrt{2}$

$Cot(\frac{\pi }{4} ) = 1$

Now the slope of the tangent

$\frac{dy}{dx} =-\frac{\pi }{4} (\sqrt{2})^{2} )+1$

$\frac{dy}{dx} =-\frac{\pi }{2} +1$

Step(iii):-

Given

Substitute $x=\frac{\pi }{4}$ in y = x cot (x)

$y = \frac{\pi }{4} cot (\frac{\pi }{4} )$

$y = \frac{\pi }{4}$

The point of the tangent line $(x ,y ) = (\frac{\pi }{4} , \frac{\pi }{4} )$

The equation of the tangent line

$y - y_{1} = m ( x - x_{1} )$

$y - \frac{\pi }{4} = (\frac{-\pi }{2} +1)( x - \frac{\pi }{4} )$

A cylinder has a height that is 2 times as large as its radius. The lateral area of the cylinder is 16π square units. What is th

Juliette [100K]

The length of the radius of the cylinder is 2 units.

The lateral surface area of a cylinder = 2πrh
where, r = base radius
h = height of cylinder
Now, height of cylinder = 2r units

⇒ 16 π = 2×π×r×h
⇒ 16 π = 2×π×r×2r
⇒ $r^{2}$ = 4
⇒ r = 2 units
Thus, radius is 2 units.
