8/(1/7)=56
It would take the artist 56 hours to paint all 8 pictures.
A perfect cube is a number that resulted from multiplying a number three times by itself. A perfect cube is also a number that has an exact cube root.
8x^12 ⇒ 2x^4 * 2x^4 * 2x^4
27x^9 ⇒ 3x³ * 3x³ * 3x³
Only two monomials are perfect cubes.
Answer:
false ignore this I needed to write something else to hand it in
By definition we have the relationship between the diameter of a circle and its radius is as follows:
r = d / 2
where
r: radio
d: diameter
Since the diameter of the circle is 4, then the radius will be given by
r = (4) / 2 = 2
answer
the radius of the circle is 2 units.
Answer:
In this problem, we are given the following functions:
and its inverse function:
First of all, we want to calculate 
. This can be obtained by substituting
x = 2
into f(x). Doing so, we find:
Then we want to calculate 
. We can do it by substituting
x = 1
into 
. Doing so,
Then we want to calculate 
, which can be found by calculating f(2) and then using it as input for 
We know that
f(2) = 1
Therefore,
Then we want to calculate 
, which can be calculated by plugging
x = -2
into . Doing so,
Then we want to calculate 
; by substituting
x = 4
into f(x), we find
Finally, we want to find 
We know already that
So we have:
