Answer:
r ≅ 3.00
Step-by-step explanation:
First we need to get the formula for finding the volume of sphere. The formula is:
Now to find for the radius, we need to input the value that we know into the formula.
Now we multiply both sides by 3/4.
Now divide both sides by π.
To find r, we finally get the cube root of both sides.
r ≅ 3.00
Answer:
1) x= -36.
2) x = 0.
Step-by-step explanation:
1) Taking the 3rd power to both sides and using the following exponent law:
we get:
So this tells us that x = -36.
2) We can distribute the power inside every term. So the left side becomes:
Now, the trick here is to remember that , so replacing 1 with
, which then gives us:
, telling us that 3x = 0 and thus, x = 0.
