Answer:

B) 5

Step-by-step explanation:

Divide the volume by the formula and you get that 1000=r^3. r is 10, but every second it gains 2 cm, so divide 10 by 2 to get 5

Find the distance<br> (-6, -5) and (2, 0)

tiny-mole [99]

Hey there! I'm happy to help!

To find the distance between two points, you find the difference between the x values, square that, find the difference between the y values, square that, add the two numbers you got, and then find the square root.

Find the difference between the x values.

-6-2=-8

Square it.

-8²=64

Find the difference between the y-values.

-5-0=-5

Square it.

-5²=25

We add the two numbers we got.

64+25=89

And we find the square root.

√89≈9.43

This method comes from the Pythagorean Theorem! If you draw a triangle that connects the two points, you can use the Pythagorean Theorem to find the distance, which is what we just did!

Have a wonderful day! :D

What is 125x9 64y12 written as a sum of cubes? (25x3)3 (4y4)3 (5x3)3 (16y4)3 (25x3)3 (8y4)3 (5x3)3 (4y4)3.

babunello [35]

The factorization of $\rm 125x^9+64$ is $\rm (5x^3+4)(25x^6-20x^3+16)$ .

<h3>Factorization;</h3>

Factorization is nothing but writing a number as the product of smaller numbers.

Given

Polynomial; $\rm 125x^9+64$

To find the factorization the polynomial equates the equation with zero following all the steps given below.

Then,

The factor of the polynomial is;

$\rm 125x^9+64\\\\125x^9+100x^6+80x^3-100x^6-80x^3+56\\\\5x^3(25x^6-20x^3+16)+4(25x^6-20x^3+16)\\\\(5x^3+4)(25x^6-20x^3+16)$

Hence, the factorization of $\rm 125x^9+64$ is $\rm (5x^3+4)(25x^6-20x^3+16)$ .

What is the approximate volume of a cone with a height of 6mm and radius of 18 use 3.14 to approximate pi

Mandarinka [93]

Hello from MrBillDoesMath!

Answer:

2035.8 (approximately)

Discussion:

The volume of a cone or radius r and height h is given by the formula:

Volume = (1/3) Pi * r^2 * h. In our case this is:

V = (1/3) Pi * (18)^2 * 6

=(1/3) Pi * 324 * 6 => 324/3 = 108

= 108 * 6 Pi => 108 *6 = 648

= 648 * Pi => approximating Pi by 3.14

= 648 * 3.14

= 2035.8 (approximately)

Thank you,

MrB

Hey guys! Could someone help me with this problem? I got the wrong answer! The answer is B, but I don’t know how to get it! Coul

asambeis [7]

When it says 'which has a greater rate of change' it is referring to 'what has a greater slope.' So, let's calculate each thing's slope:

Table:
I'm going to pick the easiest values to work with, so I'll pick the points (0, -2) and (1, -9/5) - I simplified the mixed fraction. So, here we go, the slope formula is:
$m =\frac{y_2-y_1}{x_2-x_1}$
$m = \frac{- \frac{9}{5} - (-2)}{1-0} = \frac{- \frac{9}{5} - ( -\frac{10}{5} )}{1-0}$
$m = \frac{ \frac{1}{5} }{1} = \frac{1}{5}$

So, the table's slope is -1/5.

Graph
We can, again, pick two points. I'll pick the two given: (5, 0) and (0, -3). Let's start off with the same formula:
$m =\frac{y_2-y_1}{x_2-x_1}$
$m = \frac{-3-0}{0-5} = \frac{3}{5}$

The graph's slope is 3/5.

Now, we just have to decide which is bigger: -1/5 or 3/5. So, clearly:
3/5 > -1/5.

The 3/5 slope was the graph, hence it has the greater rate of change (that's why it's B). If anything doesn't make sense, feel free to DM me or ask!
