Answer: The formula to calculate the radius of a sphere if we know the volume is: Cubic root [3V/(4∏)].

Solution:

The formula for the volume (V) of a sphere is:

V=(4∏/3) r^3

Solving for r: Multiplying both sides of the equation by 3/(4∏):

3/(4∏) V = 3/(4∏) [(4∏/3) r^3]

3V/(4∏) = r^3

Cubic root both sides of the equation (raising to the power 1/3):

Cubic root [3V/(4∏)] =Cubic root (r^3)

Cubic root [3V/(4∏)] = r

r = Cubic root [3V/(4∏)]

Answer:

Bill has $21.

Step-by-step explanation:

There's $135. 84/4=21. At the same time, 21+9=30. 30+21+84=135.

Factor the polynomial F(x) =x^3-x^2-4x+4 completely.

Norma-Jean [14]

Answer:

Step-by-step explanation:

PART 1:

Possible roots by noticing the coefficient of first term:

x = 1, -1

PART 2:

1 | 1 -1 -4 4

1 0 -4 0

The remainder is zero, hence one factor is (x-1)

PART 3:

$x^3-x^2-4x+4=(x^2-4)(x-1)\\\\x^3-x^2-4x+4=(x+2)(x-2)(x-1)$

PART 4:

$f(x)=(x+2)(x-2)(x-1)\\\\=(x^2-4)(x-1)\\\\=x^3-4x-x^2+4\\\\=x^3-x^2-4x+4$

Mi is about to roll a six-sided number cube. What is the experimental probability that she will roll an even number based on her

Kryger [21]

Answer: The experimental probability that she will roll an even number= $\frac{1}{2}$

Step-by-step explanation:

We know that the probability for any event is given by6;-

$\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

In a dice, the total even numbers (2,4,6)= 3

Therefore, the probability that she will roll an even number will be given by:-

$\text{Probability}=\frac{\text{3}}{\text{6}}=\frac{1}{2}$

Hence, The experimental probability that she will roll an even number= $\frac{1}{2}$
