Use implicit differentiation to find an equation of the tangent line to the curve at the given point.

kenny6666 [7]

Hello:
Use implicit differentiation : <span>y sin 12x = x cos 2y
y' sin12x+12ycos12x =cos2y -2x y'sin2y
when : x = </span>π/2 and y =π/4<span>

</span>y' sin12(π/2) +12(π/4)cos12(π/2) =cos2(π/4) -2(π/2) y'sin2(<span>π/4)
</span>y' sin(π/6) +(π/3)cos(π/6) =cos(π/2) - π y'sin(π/2)

y' (1/2) +(π/3)(√3/2) = - π

y' (1/2) =-(π/3)(√3/2) - π
y' = -π (1+√3)/3
an equation of the tangent line is : y- π/4 = ( -π (1+√3)/3)(x-<span>π/2)</span>

Answer the Question the volume based Question. I will make uh brainliest + 50 points

Dimas [21]

<h3><u>Part A</u></h3>

To show the total capacity of container B is 132 cm³

volume = unit rate × time taken

volume = 6 cm³ × 22

volume = 132 cm³ ∴ Hence proved.

<h3 /><h3><u>Find radius</u></h3>

$\sf volume \ of \ cone = \dfrac{1}{3} \pi r^2 h$

===================

$\rightarrow \sf \dfrac{1}{3} * \dfrac{22}{7} * r^2 * 14 = 132$

<em>simplify</em>

$\rightarrow \sf \dfrac{44}{3} * r^2= 132$

<em>change sides</em>

$\rightarrow \sf r^2= \dfrac{132(3)}{44} = 9$

<em>square root both sides</em>

$\rightarrow \sf r = 3$

∴ Hence the radius of cone (Shape B is 3 cm)

<h3><u>To show the time taken</u></h3>

volume = unit rate × time taken

$\sf volume \ of \ hemi -sphere = \dfrac{2}{3} \pi r^3$

=========================

$\sf \rightarrow \dfrac{2}{3} \pi r^3 = 6 * time \ taken$

<em>Insert values</em>

$\sf \rightarrow \dfrac{2}{3} *\dfrac{22}{7} \ r^3 = 6 * time \ taken$

<em>exchange sides</em>

$\sf \rightarrow time \ taken = \dfrac{2}{3} *\dfrac{22}{7} \ r^3 *\dfrac{1}{6}$

<em>simplify following</em>

$\sf \rightarrow time \ taken = \dfrac{22}{63}r^3$
