Solution, solve\:for\:x,\:\left|x\right|-8=-5\quad :\quad x=-3\quad \mathrm{or}\quad \:x=3

Steps:

\left|x\right|-8=-5

\mathrm{Add\:}8\mathrm{\:to\:both\:sides}, \left|x\right|-8+8=-5+8

\mathrm{Simplify}, \left|x\right|=3

|f\left(x\right)|=a\quad \Rightarrow \:f\left(x\right)=-a\quad \mathrm{or}\quad \:f\left(x\right)=a, x=-3\quad \mathrm{or}\quad \:x=3

A square pyramid has a volume of 20 cubic feet and a base length of 5 feet. What is it's height?
erastova [34]

Answer:

The height of the pyramid is 2.4\ ft

Step-by-step explanation:

we know that

The volume of a square pyramid is equal to

V=\frac{1}{3}b^{2}h

we have

V=20\ ft^{3}

b=5\ ft

substitute and solve for h

20=\frac{1}{3}(5)^{2}h

60=(25)h

h=60/(25)=2.4\ ft
