The radius of a sphere is 5 yards. Find the<br> volume of the sphere.
FinnZ [79.3K]

Answer:

V = 523.6 yd³

Step-by-step explanation:

The equation for the volume of a sphere of radius r is

V = (4/3)πr³

and if we substitute 5 yds for r, we get

V = (4/3)*π*(5 yd)³, or

V = (4/3)·π·125 yd³, or approxomately

V = 523.6 yd³

f(X) = 9x^3 + 2x^2 - 5x^3 - 7x + 4 and g(X) = 5x^3 - 7x + 4. what is f(X) - g(X)? Show all of your steps and write your final an
dolphi86 [110]
First we can simplify f(x) to make it a little easier. We can write it as
4x^3+2x^2-7x+4 by combining like terms

The we just subtract g(x) from f(x) and simplify
4x^3+2x^2-7x+4-(5x^3-7x+4) and remember to distribute the negative to g(x)
4x^3+2x^2-7x+4-5x^3+7x-4 (combine like terms)
-x^3+2x^2
In factored form, this becomes
-x^2(x-2)

Hope this helps

A bag contains 28 blue marbles and 12 red marbles. If Milton removes two marbles without replacing them, what is the probability
Daniel [21]
The probability the first marble will be blue is 28/40 
The probability the second marble will be red is 12/39 
The reason is because 28 + 12 = 40, so this makes the denominator for our first outcome, but then a marble is removed making our denominator 39 because 40-1 = 39.
