F (x) =2x -4; find f (-4)
NemiM [27]

Answer:

f(-4) = -12

Step-by-step explanation:

f(x)=2x-4

To calculate f(-4), we need to substitute x in our equation above with -4:

f(x)=2x-4\\f(-4) = 2*(-4) - 4\\f(-4) = -8-4 = -12

Note that 2*(-4) = -8

Answer: f(-4) = -12

A hemisphere has a diameter of 26 centimeters. What is the volume of a sphere with the same radius?
salantis [7]
r= \frac{d}{2}= \frac{26}{2} \;\Rightarrow r=13\,cm  \\  \\ 
V= \frac{4}{3} \pi r^3 \\  \\ 
V= \frac{4}{3} \pi \,(13)^3 \\  \\ 
V= \dfrac{4\cdot 2197}{3} \pi \\  \\ 
V= \frac{8788}{3} \pi\approx 9202,77\,cm^3
