Answer:

V≈523.6

Step-by-step explanation:

Solution

V=4 /3πr^3=4/ 3·π·53≈523.59878

The formula for the volume of a sphere is V = 4/3 πr³.

What is the solution to the equation (3/ m+3)-(m/3-m)= (m^2+g/ m^2-g)
Ilia_Sergeevich [38]

Answer:

No solution.

Step-by-step explanation:

I must correct your given equation because it must read like this:

(3/(m+3)) - (m/(3-m)) = (m∧2+9)/(m∧2-9)  

Now we can solve it:

First we will transfer the fraction from the right to the left side of the equation.

(3/(m+3)) - (m/(3-m)) - (m∧2+9)/(m∧2-9) = 0

We will change binomial sign (3-m) = - (m-3) and that change sign of the second fraction from - to + , also we will change (m∧2-9) which is difference squared to (m-3)(m+3) and we get:

(3/(m+3)) + (m/(m-3)) - (m∧2+9)/(m-3)(m+3) = 0

The smallest common denominator for this equation is (m+3)(m-3)

when we multiply entire equation with (m+3)(m-3) we get:

3·(m-3) + m·(m+3)-(m∧2+9) = 0 => 3m-9+m∧2+3m-m∧2-9=0 =>

6m-18=0 => 6m=18 => m=18/6 = 3 => m=3

But we have conditions (m+3)(m-3) ≠ 0 => m+3≠0 and m-3≠0 => m≠-3 and m≠3

We conclude that this equation does not have solution.

Good luck!!!

A car leaves town traveling 40 mi/h. Two hours later, a second car leaves the same town, on the same road, traveling at 60 mi/h.
borishaifa [10]
Don't really know how to use that formula, but the second car will past the first after 4 hours. 
1      240 = 40(6) 
2      240 =60(4)

First car has a "t" of 6, because the second car traveled two hours later.
