Step-by-step explanation:

s = 2pirh

s ÷ 2 = pirh

s ÷ 2pi = rh

s ÷ 2pih = r

You just need to divide both sides by 2\pi h: the equation becomes

s = 2\pi rh \iff \dfrac{s}{2\pi h}=\dfrac{2\pi rh}{2 \pi h} \iff \dfrac{s}{2\pi h}=r

Lim x-0 3x²/(1-cos5x)
mylen [45]

The limit is presented in the following undefined form:

\displaystyle \lim_{x\to 0}\dfrac{3x^2}{1-\cos(5x)} \to \dfrac{3\cdot 0^2}{1-\cos(5\cdot 0)} = \dfrac{0}{0}

In cases like this, we can use de l'Hospital rule, which states that this limit, if it exists, is the same as the limit of the derivatives of numerator and denominator.

So, we switch

\dfrac{f(x)}{g(x)}\to\dfrac{f'(x)}{g'(x)}

The derivative of the numerator is

\dfrac{d}{dx} 3x^2 = 6x

Whereas the derivative of the denominator is

\dfrac{d}{dx} (1-\cos(5x)) = 5\sin(5x)

So, the new limit is

\displaystyle \lim_{x\to 0}\dfrac{6x}{5\sin(5x)} \to \dfrac{6\cdot 0}{5\cdot 0} = \dfrac{0}{0}

So, it would seem that we didn't solve anything, but indeed we have! Recall the limit

\displaystyle \lim_{x\to 0} \dfrac{ax}{\sin(bx)} = \dfrac{a}{b}

to conclude that the limit converges to \dfrac{6}{25} [/tex]

Eric drove 113 miles on Monday. On Tuesday, he drove 33 miles less than Monday. How far did he drive both days?
Marat540 [252]
He drove 193 mile you subtract 33 from 113 which is 80 then add 80 and 113 together and you get 193
