The dimensions of a figure are doubled, how many times larger will the volume be? Only enter numerical answers

1 answer:

3 0

Answer:if you double all of the dimensions of a rectangular prism, you create a similar prism with a scale factor of 2. The surface area of the similar prism will increase as the square of the scale factor (22 = 4) and the volume will increase as the cube of the scale factor (23 = 8).

A potential energy function is given by U = A x3 + B x2 − C x + D . For positive parameters A, B, C, D this potential has two eq

Ivenika [448]

Answer:

7.8655

Step-by-step explanation:

Given the functionl

$U=Ax^3+Bx^2-cx+D$

Where,

$A=1.45J/m^3\\B=2.85J/m^2\\c= 1.7J/m\\D=0.6J$

We have, replacing,

$U=1.45x^3+2.85x^2-1.7x+0.6$

We need to derivate and verify for stable equilibrum that,

$\frac{d^2 U}{dx^2}>0$

Then,

$U'(x) = 4.32x^2+5.7x-1.7$

Roots in,

$x_1=-1.57008\\x_2=0.250636$

We obtain U"(x), then we have

$\frac{d^2U}{dx}=8.64x+5.7$

For $x=-1.57, U"(x)=-7.86549$ Unestable

For $x=0.250636 U"(x)=7.8655>0$ Stable

There are 60 marbles in a bowl. 1/3 of them is red, 1/4 is blue and the rest has now colour. How many marbles have no colour?

Gwar [14]

Answer:25

Step-by-step explanation: since 1/3 of the marbles is red, we’ll divide 60 by 3, which equals 20. Since 1/4th are blue, we’ll do 60/4=15. 20+15=35. We’re finding the amount with no color, so subtract 35 from 60. We have 25
