Area of rectangle = x(x+2) = x^2 +2x

area of triangle = x*2/2 = x 

so the shaded fraction of the rectangle will be x(x+2)/(x+2)=x

Answer:

x=81 or 1/3

Step-by-step explanation:

x^\log_3(x)} =81x^3\\\log_3(x^{\log_3(x)})=\log_3(81x^3)\\\(\log_3x)(\log_3x)=\log_381+\log_3x^3\\(\log_3x)^2=3\log_3x^+4\\\\Let u=\log_3x\\\\u^2-3u-4=0\\(u-4)(u+1)=0\\u=4 \\4=\log_3x\\x=3^4=81\\\\u=-1\\-1=\log_3x\\x=3^{-1}=1/3

Let A be the area of a circle with radius r. If dr/dt=3, find dA/dt when r=2.
astraxan [27]
\bf \textit{area of a circle}=A=\pi r^2&#10;\\\\\\&#10;\cfrac{dA}{dt}=\pi \cdot 2r^1\cdot \cfrac{dr}{dt}\implies \cfrac{dA}{dt}=\pi \cdot 2r\cdot \cfrac{dr}{dt}\quad &#10;\begin{cases}&#10;r=2\\&#10;\frac{dr}{dt}=3&#10;\end{cases}&#10;\\\\\\&#10;\cfrac{dA}{dt}=\pi \cdot 2(2)(3)
