Find the derivative of x³/tanx

juin [17]

Answer:

Below.

Step-by-step explanation:

We apply the quotient rule:

dy/dx = ( tanx * 3x^2 - x^3 * sec^2x) / (tan^2 x)

= x^2( 3tanx - xsec^2x) / tan^2x

Between the time Iko woke up and lunchtime, tue temperature rose by 11 degrees. Then by the time he went to bed, the temperature

Ierofanga [76]

Answer:

$T_b=(x-3)\textdegree$

Step-by-step explanation:

let x° be temperature when he woke up. Given that the temperature rose by 11° then later dropped by 14°. Also let $T_b$ be temperature at time she went to bed.

-We add the temperature rise and subtract the temperature drop to find temperature at time she goes to bed.

-The temperature relative to time of waking up can be expressed as:

$T_b=x\textdegree\pm\bigtriangleup T\textdegree\\\\T_b=x\textdegree+11\textdegree-14\textdegree\\\\T_b=(x-3)\textdegree$

Hence, the temperature relative to the time Iko woke up is (x-3)°

the formula for the volume of a cone can be constructed using what fraction of the area of a circle formula?

ss7ja [257]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\\\\
-------------------------------\\\\
\textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\implies V=h\left( \stackrel{\textit{a third of a circle's area}}{\cfrac{\pi r^2}{3}} \right)$
