26.6 repeating a line should be over the 6 couldn't figure out how to do on my phone or 26.66666666666666

Step-by-step explanation:

80 divide by 3 26.6 repeating 9 minus 3 is 6 6 divide 160 is 26.6 repeating 21 minus 9 is 12 12divided by 320 is 26.6 repeating

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

Plot point for negative 4 and negativie 1

Allushta [10]

Answer:

Step-by-step explanation:

(-4, -1) is what you asked to be plotted.

The first number is what number you go to on the x axis (horizontal).

The second number is what number you go to on the y axis (vertical).

I've attached a picture to help demonstrate. :)

The way I remember which comes first is to keep it alphabetical. X comes first, so go on the x axis first, then y

Find the missing side

dybincka [34]

Answer:

7) 8.94

8) 6.71

Step-by-step explanation:

for both questions, use pythagorean theorem

$a^{2} + b^{2} = c^{2}$

<u>Question 7:</u>

$4^{2} + 8^{2} = c^{2}$

16 + 64 = $c^{2}$

80 = $c^{2}$

$\sqrt{80} = \sqrt{c^{2}}$

c = 8.94

<u>Question 8:</u>

$6^{2} + 3^{2} = c^{2}$

36 + 9 = $c^{2}$

45 = $c^{2}$

$\sqrt{45} = \sqrt{c^{2} }$

c = 6.71

Determine all critical points for the following function. f(x)=x2−14x+1

melomori [17]

9514 1404 393

Answer:

(x, y) = (7, -48)

Step-by-step explanation:

A critical point is where the slope is zero or undefined. A polynomial function will never have any points where the slope is undefined.

The slope is zero were f'(x) = 0.

f'(x) = 2x -14

0 = 2x -14

0 = x -7

7 = x

f(7) = 49 -98 +1 = -48

The critical point is (7, -48).
