During play, a ball with a diameter of 3.00 inches splits exactly in half. What is the volume of each portion of the ball?
Luba_88 [7]

Answer:

7.05 in^3

Step-by-step explanation:

V = 4/3(pi)r^3 , r = 3/2 = 1.5

V = (4/3)(3.14)(1.5^3)

= 14.10

Now divide by 2 for 1/2 of the ball.

V/2 = 14.10 = 7.05

= 7.05 in^3

Perform the indicated operation to write given polynomial in standard form: (2x^3 − 6x^2 − 7x − 2) +(x^3 +x^2 +6x − 12)
Kipish [7]

Answer:

\left(2x^3-6x^2-7x-2\right)+\left(x^3+x^2+6x-12\right)=3x^3-5x^2-x-14

Step-by-step explanation:

To add the polynomials

Remove parentheses:

\left(2x^3-6x^2-7x-2\right)+\left(x^3+x^2+6x-12\right)=2x^3-6x^2-7x-2+x^3+x^2+6x-12

Group like terms:

=2x^3+x^3-6x^2+x^2-7x+6x-2-12

Add similar elements:

=3x^3-6x^2+x^2-7x+6x-2-12\\=3x^3-5x^2-7x+6x-2-12\\=3x^3-5x^2-x-2-12\\=3x^3-5x^2-x-14

The Standard Form for writing down a polynomial is to put the terms with the highest degree first,its term of 2nd highest is 2nd etc..

In our case the standard form is  

\left(2x^3-6x^2-7x-2\right)+\left(x^3+x^2+6x-12\right)=3x^3-5x^2-x-14
