The volume of a cube with side length equal to x, is
,
thus, the volume of a cube shaped box, whose side length is (5a+4b) is :
,
The volume is already expressed in terms of a and b, but we can expand the expression
, as follows:
Answer:
,
or
Move down c units means minus 2 from whole function
f(x) moved down 2 units means f(x)-2
so
f(x)-2=2x²-8-2
f(x)-2=2x²-10
g(x)=2x²-10
First multiply both 4 and 18:
4*18=72
According to formula:
G(a1.a2) = sqrt(a1.a2)
G(a1.a2.a3) = 1/3 root of (a1.a2.a3)
As there are only 2 numbers whose geometric mean to be calculated, we take square root of multiplication of two numbers.
Sqrt(72) = 8.4852
Answer:
39,800+x0.18= his total pay
