Answer:
_____________________________
       The problem is that the "volume" of cube is equal to the length of one of its sides, "cubed" ;  that is,  "V = s³ " .    

A cube with with sides that measure 5 cm has the following volume:
_____________________________________________________
         " V  =  (5 cm)³  =  5 * 5 * 5 * cm³  =  125 cm³ " ;
 _____________________________________________________
The volume of cube with sides that measure "10 cm" 
      (which is, in fact, has "side lengths that are TWICE the value of  "5 cm" ; gets "cubed" — as opposed to getting multiplied by "2"). 
_____________________________________________________
    So, V = (10 cm)³ = 10 * 10 * 10 * cm³ = 1000 cm³ .
______________________________________________________
When we deal with "volume increases";  we are dealing with "three-dimensional objects",  with values of "cubic units" .  And in a cube, with all side lengths being equal, an increase in side length will result in an "exponential" increase in volume.
________________________________________________
So;  (10 cm)³   ≠  2* (5 cm)³.

Answer: area

Step-by-step explanation:

        Area is solved with L * W

        Volume is solved with L * W * H

        Using these formulas we can see that area uses 2-dimensions, the length and the width, while volume uses 3.

HELP NEEDED solve 54/ 2x + 1
Sav [38]
<u><em>It cannot be simplified. </em></u>The 54 and the 2 cannot be reduced because the 2 is attached to the +1 and it is against the laws of mathematics to do that.

What is the equation of the line ?
Ronch [10]

Look at the picture.

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-3, -3) and (2, 0). Substitute:

m=\dfrac{0-(-3)}{2-(-3)}=\dfrac{3}{5}\\\\y-0=\dfrac{3}{5}(x-2)\qquad|\text{use distributive property}\\\\y=\dfrac{3}{5}x-\dfrac{6}{5}\qquad|\cdot5\\\\5y=3x-6\qquad|-5y\\\\0=3x-5y-6\qquad|+6\\\\3x-5y=6

Answer:

point-slope form: y=\dfrac{3}{5}(x-2)

slope-intercept form: y=\dfrac{3}{5}x-\dfrac{6}{5}

standard form: 3x-5y=6

Line segment ON is perpendicular to line segment ML. What is the length of segment NP?
boyakko [2]

Answer:

2 units.

Step-by-step explanation:

In this question we use the Pythagorean theorem which is shown below:

Given that

The right triangle OMP

The hypotenuse i.e OM is the circle radius =5 units.

The segment MP = 4 units length

Therefore

OP^2 + MP^2 = OM^2

OP^2 + 4^2 = 5^2

OP^2 + 16 = 25

So OP is 3

Now as we can see that ON is also circle radius so it would be 5 units

And,

ON = OP + PN

So,

PN is

= ON - OP

= 5 units - 3 units

= 2 units
