actually, there are 3 modes: 6.5, 7, and 7.6

1: Calculate the slope from the origin to a point ( do this for all points)

2: Calculate distance using distance formula

3: Multiply distance by scale factor

4: graph the results

ANYTIME DUDE!!!

As long as its something I know

Nice job DBZ !

No you don't......you are dealing with radii     one radius is  8 the inner is 5

Ooops....dbz      volume  is 4/3 pi r^3

Volume of the 8cm sphere - volume of 5 cm sphere = glass volume

volume of a sphere = 4/3 pi r^3     Get your calculations on !

= 4/3 pi (8^3 - 5^3)   = 516 pi = 1620.2 cm^3

well, !'m not good at explaining but you need to find the GCF of the numbers

30

1.2, 3, 5, 6, 10,16, 30

18

1, 2, 3, 6, 9, 18

So, all i did was write out the factors and found the GCF

Answer: 6in

I do kinda get what you're doing, just not how you get the low point. I'm not the greatest at math :/ Thanks for the answer! So:

h = 1/225 a^2

h = 1/225 * 15^2

1/225 * 15^2 = 1/225 * 225 = 1

h = 1

and

- 30/225 * a + 1

- 30/225 * 15 + 1

- 2 + 1 = -1

h = -1

The only root of x^3-x+2 is   -1.5214  (by graphing)

-1.5214^6 - ( -1.5214)^2 +4(-1.5214) = 4.00

Here is an old post for when things are not working properly.

I don't really understand. Can you explain to me in another way?

Thanks for the help already! Take your time (:

Whose areas are what?

A spherical tank has a radius of 6 yards. It is filled with a liquid that costs $7.50 per cubic yard.

What is the total value of the liquid in the tank?

Volume is 4/3 π r³  =  4/3 x 3.14 x 216  =  904.32 yd³

904.32 yd³ x $7.50 $/yd³  =  $6,782.40
