If f(x)=log2(x+4), what is f^-1(3)?

zalisa [80]

$f\left( x \right) =\log _{ 2 }{ \left( x+4 \right) } \\ \\ \log _{ 2 }{ \left( x+4 \right) } =y\\ \\ { 2 }^{ y }=x+4$

$\\ \\ x={ 2 }^{ y }-4\\ \\ \therefore \quad { f }^{ -1 }\left( x \right) ={ 2 }^{ x }-4\\ \\ \therefore \quad { f }^{ -1 }\left( 3 \right) ={ 2 }^{ 3 }-4=4$

What is the approximate radius of a sphere of volume 528 m³? round the answer to hundreth

makvit [3.9K]

$\\ \sf\longmapsto V=\dfrac{4}{3}πr^3$

$\\ \sf\longmapsto 528=\dfrac{4}{3}πr^3$

$\\ \sf\longmapsto \pi r^3=528\times \dfrac{3}{4}$

$\\ \sf\longmapsto πr^3=32(3)$

$\\ \sf\longmapsto \pi r^3=96$

$\\ \sf\longmapsto 3.14r^3=96$

$\\ \sf\longmapsto r^3=\dfrac{96}{3.14}$

$\\ \sf\longmapsto r^3=30.57$

$\\ \sf\longmapsto r=3.09m=3.1m$
